Cannabinoids Profiling & Analysis

Potency analysis is the process of identifying and quantifying cannabinoids in cannabis and cannabis related products. Potency screening aids the cannabis industry in analyzing the level of cannabinoids in cannabis products so consumers are armed with the proper information to make an informed decision on proper dosing and the type of medicines they require to best suit their needs. This unique testing allows individuals to make educated decisions concerning the cannabis products they consume. Potency analysis is generally performed with either Gas Chromatograph (GC) or an High Pressure Liquid Chromatograph (HPLC)

Microbiological Contaminants & Mycotoxin Screenings

Plant matter, including cannabis, are ideal breeding grounds of many types of bacteria and molds. Many of the mold species are capable of creating compounds that are known for causing certain diseases and cancers-mycotoxins. Consumers that are experiencing immune system impairments are at high risk from mycotoxin contaminated products. Mycotoxin & contaminant testing has been done regularly with a High Performance Liquid Chromatograph with a Fluorescence Detector and a Post Column Reactor.

Terpenes Profiling

Terpenes (TUR-peen) are a large class of organic hydrocarbons produced by a wide variety of plants, and are referred to as terpenoids when denatured by oxidation (drying and curing the flowers). They are the main building block of any plant resin or "essential oils" and contribute to the scent, flavor, and colors. Some are known to have medicinal value. Our test includes: α-Pinene, Camphene, Myrcene, β-Pinene, 3-Carene, α-Terpinene, Ocimene-1, Limonene, p-Cymene, Eucalyptol, g-Terpinene, Terpenolene, Linalool, Isopulegol, Geraniol, β-Caryophyllene, Humulene, Nerolidol-1, Guaiol, Caryophyllene Oxide, α-bisabolol.

Residual Solvent Analysis

Residual solvent analysis is important for any highly-concentrated forms of cannabis. When butters, oils, wax and shatters are created, solvents are used to extract the cannabinoids from the physical plant material. There are three classes of residual solvents based on their assessed risk to human health. Repeated exposure to residual solvents can cause significant health issues to consumers, including allergic reactions, headaches, nausea and more. Most often, residual solvents are analyzed with a Gas Chromatograph with an FID detector and a headspace autosampler.

Pesticide & Herbicide Analysis

Pesticides, herbicides and insecticides can cause severe health risks to consumers of cannabis products. The chemicals that are used to create the pesticides can have side effects that can pose serious health problems for those who use cannabis. Pesticides are chemicals that are used to kill off fungus, insects and bacteria, among other things. Understanding what is being ingested, whether the product is inhaled or consumed, is pertinent in maintaining a safe and effective product. Dangerous side effects from pesticides include liver damage, cancer and decreased muscle function, to name a few. The exposure hazard to people with weaker immune systems could pose life threatening side effects. Promising that products are free of pesticides, fungicides or insecticides is not only good for your business, but is also good for the safety and well-being of your clientele. Pesticide qualification and quantification can be performed with mass spectrometers, which are the most sensitive at detecting the largest number of pesticides.

Heavy Metal Analysis

ICP/MS and AA Spectrophotometers have been reliable sources of instrumentation to test for heavy metals. The significance in testing for metals, such as lead, mercury, cadmium and arsenic is imperative. Reducing the exposure to these heavy metals will reduce the risk of adverse health effects, especially in those consumers who have an already compromised immune system.

4. How long does my sample take to test?

All potency test results will be posted to your account the next business day, by midnight or sooner all dependent on workflow, sample load and time/day of the week. We strive to get results to you within 24hrs or sooner! Wet flower samples will take longer than 24hrs. Terpene, Residual Solvent and Microbiological testing services can take up to 3 days for results. For Pesticide Analysis, please consult the laboratory.

9. What is the difference of a Standard Potency test (Gas - GC/FID) and a Premium Potency Test (Liquid -HPLC)?

The GC for Standard Potency is an instrument which uses heat to separate the cannabinoids. This process activates any acidic versions of cannabinoids (THC-A, CBD-A) and will give a total potential readout of THC (delta-9), CBD and CBN. This test will best mimic smoking, vaporizing and dabbing.

The HPLC for Premium Potency is an instrument which uses high pressure and liquid to separate the cannabinoids and read them through the column. Since this process does not use any heat, it can read many more cannabinoids, such as the ones we test for: THC (delta-9), THC-A, CBD, CBD-A, CBN and CBG. This process is best for mimicking eating cannabis or applying it to the skin.

10. Can I post my results to WeedMaps?

Yes! Sign into your SD PharmLabs Account. Click your Name. Click Edit Integrations. Select WeedMaps. Copy and paste your WeedMaps URL Web Address. Tab down. Wait for information to load. Select if you’d like your results to load automatically or if you’d like to approve in WeedMaps before.
