Chemist

About the Role

Method Development & Analytical Validation

• Analyze complex customer process stream compositions to design custom chromatographic separation methods.
• Define optimum column stationary phase chemistries, film thicknesses, particle sizes, internal diameters, and column length combinations.
• Calculate and optimize physical property calculations within GC software scripts.
• Prepare calibration standards, run repeatability and drift studies, and establish method detection and quantification limits.

Column Chemistry & Preparation Oversight

• Establish technical recipes and quality control standards for column packing and phase coating/deactivation.
• Work with lab technicians to audit column preparation workflows and troubleshoot column batch variations.
• Conduct root-cause analysis on column degradation, stationary phase stripping, and matrix contamination.

Engineering & Application Support

• Collaborate with proposal engineers during bidding to confirm theoretical feasibility of challenging stream compositions.
• Provide analytical support to tuning engineers during factory acceptance testing.
• Prepare application notes, calibration protocols, chemical safety datasheets, and analytical technical guides.

Qualification and Experience

• Master's or Bachelor's Degree in Chemistry, Analytical Chemistry, Chemical Engineering, or a related physical science.
• 4-7 years of professional experience in chromatography method development or application engineering with exposure to gas chromatography.

Competencies and Skills

• Analytical problem-solving for complex separation issues, peak co-elutions, baseline drift, and matrix interference.
• Precision and scientific rigor in analytical accuracy, calibration integrity, and record-keeping.
• Cross-functional collaboration with technicians, tuning engineers, and project managers.
• Deep knowledge of gas chromatography principles and detector mechanics (FID, TCD, FPD).
• Familiarity with international standard test methods such as ASTM D1945, ASTM D5504, GPA 2261, and ISO 6974.
• Hands-on proficiency with GC data handling systems, peak integration algorithms, calibration routines, and chemical safety management.
