About The Position

The TO-15 Analyst performs laboratory analysis of volatile organic compounds (VOCs) in ambient air, indoor air, soil gas, and related air samples using gas chromatography/mass spectrometry (GC/MS). The role produces accurate, defensible, and timely results in accordance with EPA Method TO-15/TO-15A, laboratory standard operating procedures, quality-system requirements, and applicable regulatory standards. The analyst also supports instrument maintenance, calibration, quality control, data review, troubleshooting, sample management, and continuous improvement within the Simi Valley air laboratory.

Requirements

Practical knowledge of analytical chemistry, chromatography, mass spectrometry, calibration, and quantitative data analysis.
Experience working in a production, environmental, industrial, or commercial analytical laboratory.
Ability to accurately interpret chromatographic and mass-spectral data.
Strong attention to detail and ability to follow controlled methods and SOPs.
Ability to manage multiple analytical batches and priorities while meeting turnaround-time requirements.
Proficiency with standard computer applications and laboratory data systems.
Effective written and verbal communication skills.
Ability to work independently and collaboratively in a quality-controlled environment.
Ability to work safely in a laboratory environment and wear required personal protective equipment.
Ability to stand or sit for extended periods and perform repetitive laboratory tasks.
Ability to safely handle and move sampling canisters and laboratory supplies.
Ability to work around compressed gases, cryogenic materials, vacuum equipment, and pressurized systems.
Ability to lift approximately 25–40 pounds, subject to applicable accommodations and company policy.
Flexibility to work overtime or alternate shifts when required to meet operational needs.

Responsibilities

Analyze air samples for VOCs using GC/MS in accordance with EPA TO-15, TO-15A, and laboratory SOPs.
Prepare and operate sample introduction systems, including preconcentrators and canister autosamplers.
Perform initial and continuing calibrations, instrument tuning, method blanks, laboratory control samples, duplicates, and other required quality-control procedures.
Review chromatograms, identify compounds, verify integrations, evaluate spectral matches, and quantify target analytes.
Assess analytical batches against acceptance criteria and document exceptions or corrective actions.
Process samples according to chain-of-custody requirements, holding times, detection-limit requirements, and project-specific instructions.
Enter, review, and authorize analytical data in the LIMS according to assigned authorization level.
Maintain complete, traceable records, including preparation, instrument, calibration, maintenance, and data-review documentation.
Perform routine preventive maintenance and first-line troubleshooting of GC/MS instruments, preconcentrators, autosamplers, vacuum systems, and associated equipment.
Support canister-cleaning and certification activities as required.
Investigate instrument or quality-control failures and assist with root-cause analysis and corrective/preventive actions.
Communicate sample issues, instrument downtime, QC concerns, and potential reporting delays to supervisors and project-management personnel.
Follow laboratory safety procedures for compressed gases, cryogens, chemicals, vacuum systems, and pressurized sampling equipment.
Participate in proficiency testing, method validation, detection-limit studies, internal audits, and quality-system activities.
Assist with training junior analysts and documenting analyst demonstrations of capability.
Maintain an organized, safe, and audit-ready work area.
Support production schedules, including occasional overtime, weekend, or adjusted-shift work when workload or client commitments require it.
Perform other laboratory duties consistent with the position.
