Chromatography Faults, Read From the Chromatogram
On the GC side: retention times drifting between runs point at a gas leak, an ageing septum or liner, or flow-controller drift. An FID that will not ignite or a baseline full of spikes is a detector or gas-purity story. Ghost peaks trace back to the inlet. We service Agilent 6890, 7890 and 8890, Thermo TRACE 1110/1300 and GC Ultra, Shimadzu and Chemito systems — leak-testing the whole gas path and proving the repair with a standard test mix whose chromatograms ship with the service report.
On the HPLC side: pump pressure that fluctuates or will not build is check valves or plunger seals; a noisy UV baseline is a D2 lamp or flow cell; injection-volume scatter is the autosampler needle seal. Shimadzu LC-20AD, Prominence, LC-2010 and i-Series, Waters and PerkinElmer stacks are overhauled with genuine-spec wear parts we keep in stock, so routine repairs are not held up waiting.
Pharma and testing labs from Chennai to Delhi keep these systems under our preventive-maintenance AMC — septa, liners, seals and check valves replaced on schedule, priority breakdown response, software connection issues included. Downtime on a release-testing instrument costs more than a year of AMC.
Email a chromatogram or pressure trace if you have one — it usually tells us the fault before the call. Call +91 95000 10101, WhatsApp +91 95000 62555 or send the enquiry form — we reply the same working day.
