GC-MS Service & Repair

GC-MS separates compounds by gas chromatography and identifies them by mass, with enough symptom overlap that a problem in the injector, column, detector, or gas supply can look identical to any of the others. ILS confirms the actual cause before any part is replaced and resolves it before it necessitates another visit.

How ILS Diagnoses and Resolves Common GC-MS Issues

GC-MS troubleshooting depends on tracing a symptom back to the actual component responsible, since a gas supply issue and a fouled detector can produce nearly identical signal loss. ILS works through the gas path systematically, checking each stage against performance data.

Injector Port Inspection and Repair

Repeated septum punctures and sample introduction gradually degrade the injector port, showing up as peak-shape distortion before causing an outright failure.

ILS inspects the injector port and liner at every scheduled visit, checking wear against actual peak data.

Column Bleed Diagnostics and Replacement

Columns degrade with thermal cycling and contamination buildup, producing bleed that raises baseline noise, particularly at higher oven temperatures.

ILS engineers evaluate column condition against baseline trends before recommending replacement.

Detector Cleaning and Calibration

Detector fouling produces a sensitivity drop nearly identical to a failing carrier gas supply, and treating the wrong one as the cause extends the visit without resolving the actual issue.

ILS verifies detector response and carrier gas flow together at every visit, cleaning the detector and resolving gas supply issues at the source.

Carrier Gas and Nitrogen Generator Service

Carrier gas supply, whether from a cylinder or a nitrogen generator, is serviced during the same visit.

ILS checks gas supply alongside the detector and column, since a supply issue can be misattributed to either.

Our GC-MS Service Capabilities

Trace Symptoms Through the Gas Path

Our engineers track a failure from carrier gas through detector output, checking each stage against actual performance data.

Train Across Platforms

Our engineers train across Agilent and PerkinElmer configurations, taking a vendor-agnostic approach to every system we service.

Schedule Around Usage

We set the visit frequency based on real run volume and instrument usage.

Verify Detector Response After Repair

We verify detector response after every repair, confirming sensitivity returns to full factory specification.

GC-MS Systems We Service

GC-MS platforms run across pharmaceutical, food and beverage, and environmental testing labs, and many depend on a nitrogen generator for carrier gas.
