Connecting Great Companies with Great People

Founded on the principle that the right person in the right role can change everything, SEU-USA is more than just a staffing agency. Consequently, we are a strategic partner dedicated to building the powerful workforces that drive business success across the USA.

Key Responsibilities

• Conduct trace-metal analysis in environmental matrices (water, wastewater, soil, sludge, biosolids, etc.) following EPA methods (200.7, 200.8, 245.1, 3050B, etc.).
• Perform sample preparation including hot-block digestion, microwave digestion, and fusion techniques.
• Operate, maintain, and troubleshoot analytical instrumentation:
• • ICP-OES and ICP-MS for multi-element quantification
  • Graphite Furnace AA (GFAA), Cold Vapor AA (CVAAS), and Cold Vapor Atomic Fluorescence (CVAFS) for mercury and other ultra-trace metals
  • UV-Vis spectrophotometry for colorimetric metal assays
• Execute full QA/QC protocols per EPA and NELAC/TNI standards: calibration curves, continuing calibration verification (CCV), blanks, laboratory control samples (LCS), matrix spikes/duplicates, and internal standards.
• Enter, review, and validate data in the Laboratory Information Management System (LIMS); flag outliers and ensure traceability.
• Participate in internal audits, proficiency testing (PT), and method validation studies.
• Collaborate with QA officers, senior analysts, and cross-functional teams on non-routine investigations, method improvements, and regulatory reporting.
• Maintain detailed electronic bench sheets and logbooks in compliance with SOPs.
