The GC‑ECD / GC‑FID Analyst is a highly skilled analytical professional responsible for performing gas chromatography analyses using Electron Capture Detection (ECD) and Flame Ionization Detection (FID) in a high‑throughput environmental production laboratory. This role requires strong hands‑on experience operating, maintaining, and troubleshooting GC‑ECD and GC‑FID instrumentation across multiple EPA and client‑specific methods, including but not limited to EPA Methods 8081, 8082, and 8015.

The Analyst is expected to maintain productivity under demanding turnaround times, ensure strict regulatory compliance, independently resolve routine technical issues, and contribute to consistent, high‑quality analytical output. This position plays a critical role in delivering defensible data in support of regulatory compliance, site remediation, and environmental monitoring programs.

• Perform routine instrument maintenance, including inlet maintenance, detector maintenance (ECD cell care, FID jet and collector cleaning), column installation, leak checks, and performance verification
• Identify and resolve routine instrument performance issues related to sensitivity, baseline stability, retention time shifts, and peak shape
• Support advanced troubleshooting activities in collaboration with senior analysts, technical specialists, and vendors
• Maintain complete and accurate instrument logs, maintenance records, and run documentation in accordance with quality system requirements

• Perform analyses using EPA 8081 (Organochlorine Pesticides), EPA 8082 (PCBs), EPA 8015 (TPH, GRO, DRO), and related GC‑ECD/GC‑FID methods
• Prepare, sequence, and analyze calibration standards, QC samples, and analytical batches in accordance with method and regulatory requirements
• Maintain consistent analytical throughput while meeting strict client turnaround times
• Evaluate chromatographic data for integration accuracy, baseline performance, and reporting limits
• Perform routine data review and reprocessing as required, documenting technical rationale for adjustments

• Ensure full compliance with EPA, state, client, and accreditation requirements (NELAC/TNI, DoD, etc.)
• Monitor method‑specific QC parameters, including continuing calibrations, blanks, LCS, MS/MSD, surrogate recoveries, and retention time windows
• Identify QA/QC exceedances and notify Laboratory Operations or QA for corrective action initiation
• Support internal audits, external assessments, and client data reviews as assigned
• Adhere strictly to SOPs, safety procedures, and data integrity requirements

• Support method optimization efforts, including column selection, temperature programs, injection parameters, and detector conditions
• Assist with validation studies, and implementation of client‑specific requirements under direction of senior staff
• Contribute to SOP updates and method performance…
