parameter

0-100 psi pressure range

technique(s)

gas chromatography (GC): suitable

General description

Install a pressure gauge in the gas delivery system to measure pressure at any given point. For example, install one upstream and downstream of the High Capacity Gas Purifier. When the pressure drop across the purifier exceeds 10 psi, the converter tube should be replaced. Kit contains:
  • 2 in. (5 cm) diameter steel and copper alloy gauge (0-100 psi)
  • NPT to Swagelok adapter
  • 1/8 in. tee
  • 18 in. (1/2 m) of 1/8 in. copper line
  • assembly and installation instructions
Nuts and ferrules included.

Application

In-line pressure gauge kit may be used to monitor the column inlet pressure of high-performance liquid chromatography (HPLC) equipment, which is further modified for carbon-dioxide supercritical fluid chromatography (SFC).
