Leak Testing: General Information
Refer to Figure 24 and Figure 25, which show the flow paths for
all gases used in EPC and MPC headspace installations.
Chromatographic symptoms such as loss of sensitivity can
result from leaks and restrictions. Use the following set of tests
for verifying leaks and restrictions within the Headspace
Sampler. Verify that the GC inlet is leak free before checking for
leaks within the Headspace Sampler.
