Gas Chromatography (GC/MS)

Listed here is one of the best Gas Chromatography (GC/MS) equipment available from Varian. Varian manufacture many type or model of GC/MS including one in this picture.

The Varian 4000 GC/MS system offers three easily switchable ionization configurations: internal ionization (II), external ionization (EI) or hybrid chemical ionization (CI).

· External Ionization

· Internal Ionization

· Hybrid Chemical Ionization (CI)

Sample introduction and separation is handled by the Varian CP-3800 GC with its proven performance and many options. Varian MS Workstation controls the 4000 GC/MS with a full complement of productivity, reporting, and regulatory compliance tools.
