This document outlines the space and resource requirements for a GC, 5975 MSD or 7000 Triple Quad GC/MS (referred to as MS in this document), and automatic liquid sampler (ALS) installation. For a successful and timely installation of the instrument, the site must meet these requirements before beginning installation. Necessary supplies (gases, tubing, operating supplies, consumables, and other usage-dependent items such as columns, vials, syringes, and solvents) must also be available. Note that performance verification requires the use of helium carrier gas and, for models using chemical ionization, methane reagent gas. Refer to the Agilent Web site at www.agilent.com/chem for the most up-to-date listing of GC, MS, and ALS supplies and consumables.
