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.
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 Chromatographer with Flame Ionization Detector (GC-FID), means we provide the most comprehensive and accurate testing available anywhere.
EVIO Labs Berkeley screens for 20 solvents and other harmful chemicals.
Limits below in parts per million.
CA Limit (PPM)
|1,2-Dichloroethane (Ethylene Dichloride)||1||Solvent, degreaser.||Potential pollutant, possible carcinogen. Banned from consumer products.|
