EL Solvents

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) 

Common Use


1,2-Dichloroethane (Ethylene Dichloride) 1 Solvent, degreaser. Potential pollutant, possible carcinogen. Banned from consumer products.
2-Propanol (IPA) 5,000 Rubbing alcohol Inhaling can cause dizziness, nausea
Acetone 5,000 Nail polish remover Neurological symptoms
Acetonitrile 410 Laboratory solvent, cosmetics Can be metabolized to hydrogen cyanide
Benzene 1 Component of gasoline, responsible for the gas station aroma Known carcinogen, leukemia
Butanes 5,000 Lighter fluid, liquified petroleum gas, propellant in aerosol sprays Inhaling can cause euphoria, drowsiness, asphysiz, cardiac arrythmia
Chloroform 1 Powerful anesthetic and sedative as popularized in 1970's soap operas. Used in pesticide formulations. Probable carcinogen, disruptive to central nervous system.  Long term exposure can cause liver and kidney damage.
Dichloromethane 1 Use to decaffeinate coffe and tea, prepare flavor extracts. Aerosol propellant, Paint stripper, Inhalation hazard can cause neurological symptoms including dizziness, loss of consciousness.
Ethanol 5,000 Drinking Alcohol, common solvent.  Presence of ethanol does not fail tinctures. Inhaling alcohol vapors can intensify intoxication and have additive effects on brain.
Ethyl acetate 5,000 Widely used solvent, in glues, nail polish remover, perfumes, decaffeinating coffee. Prolongued exposure can lead to drowsiness and unconsciousness.
Ethyl ether 5,000 Solvent used for fatty and resinous substances. Irritating to eyes, respiratory, skin. Prolonged exposure can lead to drowsiness and unconsciousness
Ethylene oxide 1 Used in surface disinfectant, detergents. Accelerator for maturation of tobacco leaves, fungicide. Very hazardous carcinogenic, anaesthetic, highly flammable
Heptane 5,000 Anesthetic, solvent, lab reagent. Adhesives, sealants, fues. May cause drowsiness, dizziness.
Hexanes 290 Extraction solvent for oilseed processing, vegetable oils. Cleaning agent Mild central nervous system effects.
Methanol 3,000 Wood alcohol.  Commonly used in lab as sample extraction. Antifreeze. Gelled version is "Sterno" fuel Potentially fatal when swallowed or intentionally inhaled at high doses. CNS depressant, affects optic nerve.


Used in production of polystyrene and insulation materials. Inexpensive solvent Irritant of skin, eyes, nose. Most common exposure from gasoline fume inhalation.
Propane 5,000 Common fuel and solvent CNS depressent at high exposures.
Toluene 890 Solvent that is insoluable in water. CNS effects, headaches, ataxia, hallucinations, nausea, seizures, coma
Trichloroethylene 1 Used in refrigerants and solvents for cleaning metals. Has been found in groundwater at military sites. Known human caricinogen with evidence linking TCE to kidney cancer and non-Hodgkin lymphoma.
Xylenes 2,170 Common solvent found in pesticide products as well as degreasers. Acute systemic toxicity when ingested.  CNS effects, headaches, ataxia, hallucinations, nausea, seizures, coma
