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.
