Application Scientist; Analytical

Application Scientist (Analytical)

Make Every Analysis Count

When a lab's LCMS method fails validation, a product launch gets delayed. When sample prep goes wrong, an entire batch of testing has to be repeated. At Filtrous, we don't just sell vials, filters, and consumables. We help analytical labs get reliable results. As our Application Scientist in Analytical Chemistry, you'll be the expert who develops validated methods, travels to customer sites to solve real instrument challenges, and creates the technical content that proves our products perform.

Your work will directly impact laboratories running critical analyses in pharmaceutical QC, environmental testing, food safety, and industrial quality control.

• Develop Methods Customers Can Trust:
  Create and validate analytical methods on HPLC, LCMS, GCMS, and ICP‑MS that meet USP, EPA, and FDA requirements.
• Be the Expert in the Field:
  Travel to customer sites to troubleshoot method failures, optimize sample preparation, and validate instrument performance.
• Solve the Sample Prep Problem:
  Develop and demonstrate optimized workflows using our filters, vials, and QuEChERS products that deliver clean, consistent samples.
