Cannabis is medicine. Medicine needs to be precise. Precise labeling leads to customer trust and loyalty, and patients medicating with cannabinoids need accurate cannabinoid concentration information levels in order to effectively treat their illnesses and safely consume recreational products.

TX Pharm Labs uses High Performance Liquid Chromatography (HPLC) that goes beyond testing normal potency levels by providing detailed cannabinoid profiling across fourteen other components including CBD, CBL, THC isomers, and CBN. All potency tests are validated by the company’s cannabis certification program that exceeds AOAC, WHO, and all State-testing requirements.

Terpenes are aroma and taste molecules that produce the characteristic smells and flavors of flowers, herbs, and spices. 

These isoprenoid molecules are also the essential medicinal biosynthetic building blocks for various phytochemicals including THCA, which can influence the overall THC homeopathic effect.

TX Pharm Labs uses gas chromatography (GC) to identify and quantify 28 distinct terpene analytes providing consumers with information to distinguish and choose products that taste and smell best to them.

Pesticides are inherently dangerous molecules. That’s why they are used, to kill microorganisms and other plant pests. The downside of this use, however, is carryover onto final products. Pesticides commonly used in cannabis cultivation are potentially dangerous and pose great health risks – the greatest danger occurring with chronic exposure to pesticide residue which is toxic at high levels and harmful at lower doses. Potentially harmful chemicals include: insecticides, fungicides, plant growth regulators, and other compounds.

TX Pharm Labs uses liquid chromatography with mass spectrometry (LC-MS/MS) for full quantitation of 67 different analytes, ensuring our procedures detect ultra-low amounts of pesticides keeping users safe and healthy.

Measuring heavy metal contamination is important for all flower, water, food, and solvent-based products. Many states have set conservative limits per gram of product for lead, arsenic, cadmium, and mercury as these compounds are very toxic to humans.

TX Pharm Labs tests for heavy metal contamination using Inductively Coupled Plasma spectrometry with mass spectrometric detection (ICP-MS). Our approach enables very sensitive analysis for metals at low concentrations in the parts per billion ensuring your products are safe to consume.

To produce highly-concentrated oils and waxes, solvents such as acetone, ethanol and butane are used to extract cannabinoids and terpenes from marijuana and hemp plant material. These harmful solvents must then be removed from final products to ensure they do not pose serious health risks when inhaled or ingested.

TX Pharm Labs uses Gas Chromatography with Mass Spectrometry detection and headspace autosampling to quantify harmful solvents, impurities, or adulterants down to sub parts-per-million (PPM) concentrations.

Microorganisms and bacteria are ubiquitous in our world. They often can grow under the same conditions as cannabis and if consumed, these contaminants could lead to serious illness.

TX Pharm Labs testing process uses qPCR and confirmatory plating to test for bacteria and fungi.

This is accomplished by extracting community DNA samples and running the purified DNA against known DNA sequences (primers) to identify specific bacterial and fungal species.

TX Pharm Labs also uses plating to screen for levels of total yeasts and molds, total coliforms, Staphylococcus aureus, Salmonella enterica, total aerobic bacteria, and bile-tolerant gram-negative (BTGN) (including Enterobacteriaceae).
