OUR TESTING MENU
Cannabinoid Potency TestingOur Cannabinoid Potency test offers a quantitative analysis of 16 Cannabinoids found in hemp derived products. Our Cannabinoid Potency test separates the acidic compounds from the neutral compounds and defines the decarboxylation ratio of a sample which is extremely helpful in formulations of a product and the dosing of a consumer. We recommend using our Cannabinoid Potency test for all hemp derived products. We use an established scientific method utilizing a High-Pressure Liquid Chromatography (HPLC) with a diode array detector (DAD) for the separation and quantification of THC, THCA, CBD, CBDA, CBG, CBN, CBDVa, CBDV, CBGa, THCV, THCVa, CBNa, Delta 8- THC, CBL, CBC, CBCa. All results are submitted as a percentage of the dry weight of the entire sample unless specifically requested in mg/g, mg/mL, and/or mg/Unit.
PESTICIDE TESTINGWe test for 66 pesticides commonly used during alternating growth stages of hemp derived cannabinoids. Our method for determining Pesticide concentration by LC MS/MS is completely quantitative and involves an extensive sample prep procedure to ensure high sensitivity and detectability. All samples are run with accompanying standard curves containing known concentrations of pesticide standards as well quality control samples to ensure high accuracy and precision. The process begins by pulverizing the plant material into a homogenous powder to ensure all parts of the flower are represented in the analysis. The material is then extracted in a solvent that solubilizes pesticides, and these compounds are then further separated from interfering compounds using additional purification steps. We have developed our sample prep process independently in our lab and we do not use any commercially available system to extract pesticide from the products.
Once the sample prep is complete, the sample is analyzed on a Triple Quadrupole Mass Spectrometer which is coupled to an HPLC. Our quantitation range spans nearly 3 orders of magnitude, ranging down to the low parts per billion for most compounds. Calibration curves and quality control analysis ensure linearity in quantitation, and this analysis is included in the report.
Panel tests: Abamectin, Acephate, Acequinocyl, Acetamiprid, Aldicarb, Azoxystrobin, Baygon (Propoxur), Bifenazate, Bifenthrin, Boscalid, Carbaryl, Carbofuran, Chlorantraniliprole, Chlordane, Chlorfenapyr, Chlorpyrifos, Clofentezine, Coumaphos, Cyfluthrin, Cypermethrin, Daminozide, Diazinon, Dichlorvos, Dimethoate, Dimethomorph, Ethoprophos (Prophos), Etofenprox, Etoxazole, Fenhexamid, Fenoxycarb, Fenpyroximate, Fipronil, Flonicamid, Fludioxonil, Hexythiazox, Imazalil, Imidacloprid, Kresoxim-methyl, Malathion, Metalaxyl, Methiocarb, Methomyl, Methyl Parathion, Mevinphos, Myclobutanil, Naled, Oxamyl, Paclobutrazol, Pentachloronitrobenzene, Permethrin, Phosmet, Piperonyl Butoxide, Prallethrin, Propiconazole, Pyrethrin, Pyridaben, Spinetoram J,L, Spinosad A, Spinosad D, Spiromesifen, Spirotetramat, Spiroxamine, Tebuconazole, Thiacloprid, Thiamethoxam, Trifloxystrobin
HEAVY METAL TESTINGUnfortunately, there is a potential of heavy metal exposure from cultivating the plant for hemp derived cannabinoids, commercialization, and intake methods. Soils used for growing hemp outdoors are frequently in peri-urban locations or near abandoned industrial and mining sites. Consequently, the presence of pollutant metals such as Lead (Pb), Mercury (Hg), Arsenic (As), and Cadmium (Cd) in the soil and water tend to be pervasive. Certain packaging's have been found to contain heavy metals, where these metals have been proven to percolate into products at high contaminating levels, which can alter or cause failing batches. Cultivation soils used indoors can also present problems especially if non-certified fertilizers and pesticides containing Lead (Pb) or Arsenic (As) are used. Hemp is a commodity typically sold by weight, some street dealers have been known to deliberately "lace" product to increase its weight. Lead (Pb) is commonly used for this and in excess amounts is visible due to its consistency and white color.
RESIDUAL SOLVENT TestingOur Residual Solvent Testing offers a quantitative analysis of 21 solvents commonly used in the extraction of hemp derived cannabinoids to make concentrated forms. If a hemp concentrate is not purged properly to eliminate solvents used in the extraction process, the residual solvent can remain in the concentrate when consumed. The residual solvents remaining in the concentrates can be very harmful when inhaled or ingested. Residual solvents are typically not acutely toxic but may have a long-term effect on exposed individuals. An exposed person may exhibit eye, nose, and throat irritation, nausea, headaches, dizziness, fatigue, allergic skin reaction and at higher levels can cause central nervous depression, respiratory and cardiac arrest. We use an established scientific method for the separation and quantification of: 1-2-Dichloroethane, Acetone, Acetonitrile, Benzene, Butane, Chloroform, Ethanol, Ethyl Acetate, Ethyl Ether, Ethylene Oxide, Heptane, Hexane, Isopropanol, M,P-Xylene, Methanol, Methylene Chloride, O-Xylene, Pentane, Propane, Toluene, Trichloroethylene.
The same conditions that are ideal for the cultivation of hemp derived cannabinoids are also ideal for the germination of hundreds of bacteria and fungi which are found in the water, soil, and air. Yeast and molds can grow in decaying vegetation and residual moisture can encourage bacterial growth. If your hemp or hemp infused products are not properly tested, the products you are consuming can be contaminated with a variety of harmful pathogens. Microorganisms in hemp can be an indication of spoilage, unsafe levels of sanitation and the potential for human pathogenesis. We recommend all manufacturers test every product before hitting store shelves and seek consulting advice on how to properly package and store the hemp derived products to increase shelf life stability. All of these preventative actions can limit consumers from getting sick and also increase the credibility of the hemp industry as a whole.
TERPENE TESTINGWhy do certain hemp strains smell and taste a certain way? Terpenes! Terpenes are a diverse group of organic HydroCarbons (C5H8), produced by a wide variety of plants. They are important building blocks for certain odors, hormones, vitamins, pigments, steroids, resins, essential oils, and CANNABINOIDS! Terpenes interact synergistically with each other for a range of different smells, qualities, and physical effects.
We use an established scientific method for the separation and quantification of 23 major Terpenes: a-Pinene, Camphene, b-Myrcene, b-Pinene, 3-Carene, a-Terpinene, a-ocimene, Limonene, p-cymene, cis-b-Ocimene, Eucalyptol, y-Terpinene, Terpinolene, Linalool, Isopulegol, Geraniol, trans-b-Caryophyllene, a-Humelene, cis-Nerolidol, trans-Nerolidol, Guaiol, Caryophyllene Oxide, a-Bisabolol
Filth and Foreign Material Inspection
Filth and foreign material inspection includes but is not limited to the identification of hair, insects, feces, packaging contaminants, and manufacturing waste and by-products in hemp derived products.
Water Activity/Moisture Testing
Our laboratory analyzes solid and semi-solid hemp derived products, such as edibles to determine water-activity level. If the water activity is at or below 0.85 Aw, the sample “passes” water activity testing. Water activity at or above .85 Aw found in a product is an indicator these are ideal conditions for bacteria’s to grow and contaminate the product in the sealed package.
Our laboratory reports the water-activity level of the sample in Aw to 2 significant figures. This information is included on certificate of analysis when required.
HEMP TESTING PROGRAM (HTP)
PharmLabs™ Hemp Testing Program (HTP) ensures your crop does not exceed the THC regulatory threshold of 0.3%. We like to refer to the HTP as an assurance program. This type of investment has been proven to achieve the following:
1. Ensure compliance for local and federal laws that the planted hemp crops are below the required total THC levels of 0.3% and get approval to harvest
2. Ensure the plants genetics match the COA's provided by the seed vendors
3. Identify contamination issues early through microbiological, heavy metal and pesticide screenings
4. Projections of the final harvested crops monetary value
5. Maximize profit through perfectly timed harvesting and optimizing CBD potency levels on the plant
6. Lock in sales contracts before harvest
Pricing is designed specifically to save you money while customized to your budget and specific testing needs.
EARLY LEAF CANNABINOID RATIO DETECTION
Do not waste your time and money transitioning into flower and not knowing! If your goal is to grow CBD rich medicines or achieve a specific CBD:THC ratio then we can help! We can detect CBD rich: THC low cannabinoids from a young plant and save months of your precious time and tons of your hard earned money from a simple test.
When is the best time to harvest your hemp crop to get the maximum potency out of your flower? We can help! Get the maximum reward from your crop!
We recommend our clients test a sample from their crop:
1) One week before their normal harvest time
2) At their normal harvest time
3) One week after their normal harvest time
Homogeneity testing is a good idea for hemp derived packaged goods to ensure you have the highest possible quality product with consistent dosing. It requires a minimum of 6 cannabinoid potency tests of separately packaged products for total THC or CBD.
Although hundreds of different cannabinoids have been identified in hemp, our Homogeneity Test establishes the amount of Total Tetrahydrocannabinol (THC) and Total Cannabidiol (CBD) contained in a submitted sample from a hemp derived cannabinoid product.
We use an established scientific method utilizing an HPLC for the quantification of THC, THCA, CBD, CBDA, CBG, CBN, CBDVa, CBDV, CBGa, THCV, THCVa, CBNa, Delta 8- THC, CBL, CBC, CBCa. All results are submitted as a percentage of the dry weight of the entire sample.
The batch is homogeneous and “passes” homogeneity testing if the relative standard deviation, with no outliers, as assessed using the Grubb’s outlier test with a significance level of 0.05, is less than 15% on average. If the relative standard deviation is greater than 15%, the batch “fails” the homogeneity test. Homogeneity testing is for informational purposes only and for the select companies that want to ensure excellence and the highest quality products on the market.
We are ISO/IEC 17025 Certified! So, what does that mean?
ISO is an acronym for the International Organization for Standardization. ISO/IEC 17025 are requirements for the competence of testing and calibration of analytic laboratories and is the main ISO standard used by testing and calibration laboratories. In most major countries, ISO/IEC 17025 is the standard for which most labs must hold accreditation in order to be deemed technically competent. In many cases, suppliers and regulatory authorities will not accept test or calibration results from a lab that is not accredited. Originally known as ISO/IEC Guide 25, ISO/IEC 17025 was initially issued by the International Organization for Standardization in 1999. There are many commonalities with the ISO 9000 standard, but ISO/IEC 17025 is more specific in requirements for competence. The ISO/IEC 17025 standard itself comprises five elements that are Scope, Normative References, Terms and Definitions, Management Requirements and Technical Requirements. The two main sections in ISO/IEC 17025 are Management Requirements and Technical Requirements. Management requirements are primarily related to the operation and effectiveness of the quality management system within the laboratory. Technical requirements include factors which determine the correctness and reliability of the tests and calibrations performed in the laboratory. Laboratories use ISO/IEC 17025 to implement a quality system aimed at improving their ability to consistently produce valid results. It is also the basis for accreditation from an accreditation body. You can trust that your testing results with PharmLabs™ will be accurate every time!
