HPLC systems carry a large share of daily analytical workload in laboratories. Performance loss, repeatability issues and unexpected failures often stem from insufficient preventive maintenance.

Pump and Fluid Path Checks

Pump seal wear condition
Mobile phase filter replacement
Leak test and pressure stability measurement
Injector needle and rotor seal inspection

Detector and Data Quality

For UV detectors, lamp life tracking, signal noise and baseline stability should be monitored regularly. Abnormal fluctuations are critical indicators for early intervention.

Performance Qualification (PQ)

PQ tests aligned with OEM procedures verify that system suitability criteria are met. In GMP environments, these records are required during audits.

When Professional Service Is Needed

Pressure fluctuations, non-reproducible peak areas or autosampler errors warrant on-site diagnosis. Stella Lab Tech offers contract maintenance plans for your Thermo Scientific HPLC fleet.
