Our Quality Control Practices
Receiving and Sampling

When we obtain new raw material, we area it in quarantine – a surely marked location separated from accepted uncooked materials. Materials in this location are solely dealt with by using personnel who acquire samples for checking out and can’t be used in manufacturing or despatched to customers till all checking out approaches and documentation is complete.

Any given cargo of uncooked fabric can incorporate countless containers of the equal product. To be certain all the fabric is up to our first-rate standards, samples are taken from each container. A composite pattern is then blended from these samples and despatched to a 0.33 birthday celebration lab for analysis.

Each pattern goes via quite a few tests. Different merchandise endure specific analyses primarily based on the product’s chemical composition and properties. A product’s specification facts sheet discloses which exams are carried out and our minimal standards. These specs are publicly posted for each and every product on the product list page.
Transparent Batch & Lot Tracking

To make certain our merchandise are steady and meet the easiest requirements of quality, each batch of uncooked cloth and each manufacturing lot of completed items is assigned a special monitoring range (LOT #) to become aware of it in the course of our quarantine, manufacturing and post-purchase processes.
Where to Find Lab Reports for Your Product

Every LOT wide variety is tied to a Certificate of Analysis (COA) from an unbiased 1/3 celebration laboratory. Each completed product’s LOT # is seen on the product label. You can locate the COAs and lab reviews for your product on the product listing, below the part titled Third Party Analysis. Batch Purity reviews refer to batches of uncooked substances which need to be successfully recognized and quantitated. Potency Audits refer to the awareness of liquid merchandise which will now not range greater than ±10% from the posted concentration.
Third Party Testing

Every batch of each and every product is despatched out for evaluation and proven by means of an unbiased 1/3 birthday party laboratory each quantitatively (purity) and qualitatively (identity) as properly as for contaminants. A listing of trying out strategies we used and a short rationalization of every is listed below:
HPLC – Purity & Identification

High Performance Liquid Chromatography (HPLC) is the approach with the aid of which most merchandise are examined for purity. This technique is utilized when there is a single molecule or classification of molecules that can be assayed for. HPLC depends on pumps to omit a pressurized liquid and a pattern combination via a column crammed with adsorbent, main to the separation of the pattern elements primarily based on the electricity of their enchantment to the adsorbent, after which they are analyzed with the aid of shining mild on the separate pattern elements as they come off the column.

Most natural compounds take in a positive quantity of light, so as they omit by using the utilized mild beam, a detector can choose up how a great deal mild is absorbed. The detector additionally documents the components’ retention time based totally on the order in which they come off the column. This output can then be analyzed based totally on height vicinity to decide the genuine nature of the sample’s elements or fed into some other analytical desktop for extra evaluation as in the case of LC-MS.
NMR Spectroscopy – Structure & Identification

Nuclear Magnetic Resonance Spectroscopy (NMR) is a spectroscopic method to take a look at nearby magnetic fields round atomic nuclei. As the fields are special or exceptionally attribute to person compounds, in cutting-edge natural chemistry practice, NMR spectroscopy is the definitive approach to perceive monomolecular natural compounds.

Samples are positioned in a magnetic discipline and the NMR sign is produced through excitation of the nuclei pattern with radio waves into nuclear magnetic resonance, which is detected with touchy radio receivers. The intramolecular magnetic subject round an atom in a molecule modifications the resonance frequency, consequently giving get entry to to small print of the digital shape of a molecule and its man or woman purposeful groups.
TLC – Purity & Identification

Thin-Layer Chromatography (TLC) is a chromatography method used to separate non-volatile mixtures. We use this technique for plant extracts made up of many distinct compounds. TLC is in reality a rudimentary 2-dimensional flash chromatography, besides the cell segment travels up a plate with the aid of capillary motion alternatively of down a column. TLC is carried out on a sheet of glass, plastic, or aluminium foil, which is lined with a skinny layer of adsorbent material, normally silica gel, aluminium oxide (alumina), or cellulose. This layer of adsorbent is recognised as the stationary phase.

Thin-layer chromatography can be used to display the development of a reaction, perceive compounds existing in a given mixture, and decide the purity of a substance.
ICP-MS – Heavy Metal Testing

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is a kind of mass spectrometry which is succesful of detecting metals and numerous non-metals at concentrations as low as one phase in 1015 (part per quadrillion, ppq) on non-interfered low-background isotopes. This is carried out through ionizing the pattern with inductively coupled plasma and then the use of a mass spectrometer to separate and quantify these ions. We use this method to check for poisonous heavy steel contamination. All merchandise endure this test, mainly for arsenic, cadmium, mercury, and lead.
Microbiology Panel – Contaminant Testing

The microbiology panel includes ensuring merchandise are beneath desirable limits for frequent and risky microbes by way of culturing samples with increase media for pathogenic species. All merchandise that are extracts of organic entities bear this panel. The assessments covered in the panel are the Total Aerobic Plate Count, Yeast; Mold Count, E. Coli presence, S. Aureus presence, and Salmonella presence.
GC-MS – Contaminant Testing

Gas chromatography–mass spectrometry (GC-MS) is an analytical approach that combines the aspects of gas-chromatography and mass spectrometry to pick out exclusive elements inside a combined check sample. Applications of GC-MS consist of drug detection, fireplace investigation, environmental analysis, explosives investigation, and identification of unknown samples. GC-MS has been viewed as a “gold standard” for forensic substance identification due to the fact it is used to operate a one hundred percent particular test, which positively identifies the presence of a specific substance. A nonspecific check only shows that any of various in a class of components is present. Although a nonspecific take a look at may want to statistically advocate the identification of the substance, this ought to lead to false wonderful identification.

We use GC-MS to check for residual solvents, pesticides and different contaminants in plant extracts.
Other Testing

Some merchandise are tough or not possible to take a look at with the aforementioned methods. In these cases, choice techniques have to be used. Those techniques can include:
Thermogravimetric Analysis – Purity

Thermogravimetric evaluation (TGA) is a technique of thermal evaluation in which the mass of a pattern is measured over time as the temperature changes. This size affords facts about bodily phenomena, such as section transitions, absorption, adsorption and desorption; as properly as chemical phenomena inclusive of chemisorptions, thermal decomposition, and solid-gas reactions (e.g., oxidation or reduction).
UV-Vis Spectroscopy – Identification & Purity

Ultraviolet–Visible Spectroscopy (UV-Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This capability it makes use of mild in the seen and adjoining UV ranges. A beam of mild is surpassed thru a answer containing the analyte, and the transmitted wavelengths and intensities are used to measure how lots of the mild is absorbed and consequently calculate the composition of the sample.
FTIR Spectroscopy – Identification & Purity

The purpose of any absorption spectroscopy (FTIR, ultraviolet-visible (“UV-Vis”) spectroscopy, etc.) is to measure how properly a pattern absorbs mild at every wavelength. The most easy way to do this, the “dispersive spectroscopy” technique, is to shine a monochromatic mild beam at a sample, measure how a good deal of the mild is absorbed, and repeat for every unique wavelength.

Fourier-Transform Infrared Spectroscopy (FTIR) is a approach used to gain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer concurrently collects high-spectral-resolution records over a vast spectral range. This confers a good sized gain over a dispersive spectrometer, which measures depth over a slender vary of wavelengths at a time.

The time period Fourier-transform infrared spectroscopy originates from the reality that a Fourier seriously change (a mathematical process) is required to convert the uncooked statistics into the true spectrum.
Titration – Purity

Titration, additionally regarded as titrimetry, is a frequent laboratory approach of quantitative chemical evaluation that is used to decide the attention of an recognized analyte. Since extent measurements play a key function in titration, it is additionally acknowledged as volumetric analysis. A reagent, referred to as the titrant or titrator is organized as a general solution. A regarded attention and extent of titrant reacts with a answer of analyte or titrand to decide concentration.

Put extra plainly, a recognized reagent is combined with a answer containing the analyte, and the bodily alternate that follows is interpreted through the chemist as indicative of composition.
Reviewing Third Party Analysis Results

After the 0.33 celebration take a look at outcomes are received, the archives are in contrast in opposition to the specs for the fabric and deemed as pass by or fail. Any cloth which fails to meet any specification is concern to similarly 0.33 birthday party testing. The fabric will be rejected if one or greater specs fail the extra testing. We will try to return the cloth to our vendor, or if that is now not feasible we will discard it. If the fabric passes all specifications, then we whole the in-house trying out process.
In-House Testing

In addition to 0.33 celebration evaluation we habits in-house evaluation with some of the aforementioned strategies as extra confirmation:
Solubility Analysis – Confirmation

Solubility evaluation is a approach for quantitatively deciding the purity of a substance thru the software of particular solubility measurements. At a given temperature, a precise quantity of a pure substance is soluble in a particular volume of solvent.
Melting Point Determination – Confirmation

The melting factor of a substance is described as the temperature vary in which the substance undergoes a section transition from strong to liquid. Any cloth for which a respectable literature melting factor fee is installed can be examined with the aid of examination of its melting point. Melting factors are pronounced as a range; the first cost is the temperature at which first soften is observed, and the 2d cost is the temperature at which full soften is achieved.
Organoleptic Analysis – Confirmation

The organoleptic information (visual appearance, texture, smell, taste) of passing uncooked fabric is documented for reference. This information is referred to when we habits an preliminary inspection of uncooked cloth for organoleptic confirmation. It is feasible for uncooked fabric to omit laboratory evaluation and fail to in shape preceding organoleptic data. This is now not always a problem, there can be a broad vary of distinction due to synthesis residuals, extraction or polymorphy. In that case we are seeking for an rationalization for why there is a distinction to preceding statistics and if crucial post samples for extra laboratory analysis.
Foreign Materials Inspection – Confirmation

Raw fabric containers are sifted and inspected for overseas materials. Any powders or beverages discovered to include overseas substances are again to the quarantine vicinity and detailed for in addition analysis.
Final Review & Release

After all trying out is entire we evaluate effects one remaining time for completeness and accuracy earlier than releasing the cloth from quarantine. Every uncooked fabric need to omit all applicable checks inside precise specs in order for the cloth to be used in production. After a cloth passes these tests, we generate a COA for the batch and cross it to production. A uncooked cloth can’t be used in manufacturing till a COA is generated.
