About the Chemist Role

Yokogawa is seeking a Chemist to join its team in Al Khobar, Eastern region. This is a full-time position requiring 5-10 years of experience. The role focuses on developing and validating analytical methods, overseeing column chemistry, and providing engineering and application support for complex process stream compositions.

Key Responsibilities

• Analyze complex customer process stream compositions (*, natural gas, NGL, LNG, refining cuts, petrochemical matrices) to design custom chromatographic separation methods.
• Define optimum column stationary phase chemistries, film thicknesses, particle sizes, internal diameters, and column length combinations for target separations.
• Calculate and optimize physical property calculations (*, Calorific Value/BTU, Density, Compressibility, Boiling Point Distributions) within GC software scripts.
• Prepare calibration standards, run repeatability and drift studies, and establish Method Detection Limits (MDL) and quantification limits for trace component analyses (*, trace sulfur, oxygenates, moisture).
• Establish technical recipes and quality control standards for column packing (packed columns) and phase coating/deactivation (capillary columns).
• Work directly with Lab Technicians to audit column preparation workflows, evaluate baseline bleed profiles, and troubleshoot column batch variations.
• Conduct root-cause analysis on column degradation, stationary phase stripping, and matrix contamination issues encountered during system testing.
• Collaborate with Proposal Engineers during the bidding phase to evaluate challenging stream compositions and confirm theoretical feasibility (cycle time, Detection limits, Peak resolution, etc).
• Provide specialized analytical support to Tuning Engineers during Factory Acceptance Testing (FAT) when handling difficult matrices, non-linear detector responses, or co-eluting peaks.
• Prepare standard application notes, calibration protocols, chemical safety datasheets (SDS), and analytical technical guides.

Qualifications and Experience

• A minimum of 5-10 years of relevant experience is required for this position.
