Page 7: Chapter 1 - Site Preparation
Site Preparation Introduction This section discusses the site preparation for the HP 5890 SERIES II (hereafter referred to as HP 5890). The following topics are discussed: Environmental considerations Power considerations Gas considerations You will need various supplies to prepare an area for the HP 5890. Hewlett•Packard' s analytical supplies catalog describes the supplies available from Hewlett•Packard.You can obtain a copy from your local sales office. - Page 8 Site Preparation Environmental considerations The HP 5890 is about 50 cm (20 in.) high. The area above the instrument should be clear. Shelves or other overhanging obstructions limit access to the top of the instrument and interfere with cooling. If space is limited, the Oven Exhaust Deflector may improve oven cooling. It diverts exhaust air up and away from the instrument.

Page 12: Gases For Capillary Columns
Site Preparation Gas considerations Gases for capillary columns Hydrogen is the recommended carrier gas for capillary analyses; helium is an acceptable alternate and nitrogen is least desirable. These detectors are compatible with packed columns which use higher carrier gas flow rates than those used with capillary columns. A separate makeup gas system brings total flow into a detector up to the rate for optimum sensitivity with capillary columns. -
