CP-Chirasil-Dex CB Columns
DB-17ms Columns
J&W DB-17ms, a mid-polar GC column virtually equivalent to (50%-phenyl)-methylpolysiloxane, delivers excellent levels of inertness for the analysis of active compounds. The column is bonded, crosslinked, and solvent rinsable, and is excellent for the analysis of pesticides and other semi volatiles. Very low bleed performance makes it ideal for a range of gas chromatography/mass spec (GC/MS) applications, for robust and accurate performance every time.
