Solvent Testing

Residual Solvent Testing

EVIO Labs tests all types of products for residual solvents.  We verify that concentrate and oil products as well as edibles are free of solvents, processing chemicals, and some substances commonly found in pesticides. Solvents are used during the extraction process, and are then evaporated from the product after the extraction process is complete.

Instruments Used

EVIO Labs uses the latest technology and state-of-the-art instruments to deliver fast and accurate results that confirm your production processes are compliant. EVIO Labs uses headspace gas chromatography to quantify harmful solvents, impurities, or adulterants down to parts-per-million (PPM). Using our Gas Chromatograph with Flame Ionization Detector (GC-FID), means we provide the most comprehensive and accurate testing available anywhere.

Exposure to residual solvents can have health effects that affect the central nervous system, and can cause irritation, dizziness, nausea, drowsiness, and loss of consciousness. See below for specific health effects of overexposure to solvents.
