Organic solvent for cleaning autosampler syringe I work in a laboratory where gas chromatography is used extensively. We handle phthalates. What are the possible wash solvent for autosampler syringe? I've been using acetone.
Methanol is less expensive. Don’t know how well it would work in your particular situation. We do semi volatiles (EPA 624) .  Methanol works fine for the GC autosampler syringe.
