This document provides instructions and notices for the use of Agilent Technologies' Agilent Inlet EPC Leak Test Gas Chromatographs product.
This document provides step-by-step instructions for conducting a leak test on Cool On-Column, Split/Splitless, and Purged/Packed inlets of the Agilent 6890 Gas Chromatograph. The procedure utilizes the Inlet EPC Leak Test Fixture (Part Number G1530-80510) to isolate the inlet system for pressure monitoring.
The manual details specific setup requirements, including entering column dimensions and setting initial pressures on the instrument keypad. It outlines a two-stage pressure test involving equilibration at 25 psi and 40 psi, followed by a 10-minute hold at 10 psi to measure pressure loss. Acceptable limits for system tightness are defined as less than 1.0 psi loss for Cool On-Column/Purged/Packed inlets and less than 0.5 psi loss for Split/Splitless inlets.
The system is considered leak tight if there is less than 1.0 psi pressure loss in 10 minutes.
The system is considered leak tight if there is less than 0.5 psi pressure loss in 10 minutes.
The system is considered leak tight if there is less than 1.0 psi pressure loss in 10 minutes.
