LC/MS/MS Analyst

Position Summary

We are seeking an LC/MS/MS Analyst to perform environmental sample analysis using liquid chromatography–tandem mass spectrometry. This position is responsible for sample preparation, instrument operation, quality control, and data review to ensure accurate and timely results. The ideal candidate has strong analytical skills, attention to detail, and experience working in a laboratory environment.

Key Responsibilities

Prepare and analyze environmental samples, including water, soil, and other applicable matrices, following approved analytical methods and laboratory standard operating procedures. Prepare calibration standards, internal standards, reagents, and quality control samples, maintaining accurate preparation and traceability records.

Operate LC/MS/MS instruments, build analytical sequences, and perform required calibration and instrument performance checks. Review chromatograms, peak integrations, compound identification, calculations, and analytical results for accuracy. Evaluate quality control results against established acceptance criteria; investigate failures and document corrective actions before results are released.

Perform routine instrument maintenance and troubleshoot issues involving sensitivity, chromatography, contamination, and carryover. Enter and review analytical data in the Laboratory Information Management System (LIMS) and maintain complete laboratory records.
