SRI 8610C GC Gas Chromatograph System Lab-cover
SRI 8610C GC Gas Chromatograph System Lab

Reason for return - Investigate faults and re-list accordingly: - We received the item with a cracke (more)d glass piece to the photoionization detector. We replaced it with a piece that was provided. - We piped the system with N2 carrier gas and gas lines carrying product to the inlet of the GC. We turned on the switch to the Photoionization detector, under high sensitivity, and can visibly see it turn on. The source is aligned. The detector is aligned.  - We programmed the event on the software to turn the valve of the 10-way valve accordingly to enable the carrier gas to bring the product through the GC. - We introduced acetone via the sample loop (inlet gas) - we saw no peaks. We introduced acetone via injection - we saw no peaks.  - I leaked checked the piping including within the detector - no issues. I checked the point of outlets to make sure flow is continuous too - no issues. - The mechanism of the valve turning - it made a cranky sound, and I am not convinced it is turning the valve.  - There may be two issues. I had figured it was the valve so I tried injecting acetone directly into the line, but we could not see any peak of acetone. (Issues with the detector?) I am not sure if the valve's squeaking/cranky sound implies it is turning but there might be an issue here too. This SRI 8610C GC Gas Chromatograph System was removed from a university lab where it was surplus to requirements. The unit powers up but we were unable to test it further at our facility. The lab did confirm however, that is in good working order. It is in very good cosmetic condition with only very minor marks from use.
