Subject: HPLC pressure certification

One of my colleagues has two HPLC (High Precision Liquid
Chromatography) instruments in his lab; one is a standard instrument
and one is a so called nanoflow UPLC (Ultra Precision Liquid
Chromatography) specialized for very sensitive analysis with flow
rates of 100 nanoliters (nL) per minute and operating pressures up to
10,000 psi. Sometime ago a Headquarters safety team conducted an
inspection and cited these instruments as requiring pressure
certification by our center people who do pressure certifications.
It appears that neither the Headquarters safety people nor our center
certification manager is familiar with liquid chromatography
instruments. We need to respond to this finding soon. Does anyone
have or know of a risk analysis for pressure on this type of
instrumentation? If anyone else has been in this situation, what was
your response to the safety finding and how was the situation resolved?
Thank you for any help you can give us.
