Residual Solvents

EVIO Labs provides residual solvent testing to ensure concentrate and oil products are free of processing chemicals such as propane and butane. 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. 

State level limits below are in parts per million.
