• Run moisture analysis by Karl Fischer titration (volumetric and coulometric)
• Run purity and impurity analysis on the GC (FID), including sample prep, injections, integration and reports
• Run routine tests: density/specific gravity, refractive index, pH, colour (APHA/Hazen), acidity, distillation range, appearance
• Advise production on cut changes and batch release from in-process results
• Approve or reject batches against spec; prepare COAs for domestic and export dispatches
• Calibrate and do daily checks on KF, GC, balances, density meter and other lab instruments; keep calibration records
• Prepare and standardise KF reagent and other lab reagents; keep reference standards
• Maintain lab records, test reports and retain samples as per GLP
• Report out-of-spec results and instrument faults to the QC In-charge at once
• Follow lab and solvent safety rules: PPE, fume hood use, chemical storage, waste disposal

• Lab instrumentation: density meter, refractometer, pH meter, colour comparator, analytical balance
• Good knowledge of glycol and solvent specs (MEG, DEG, TEG, common solvents)
• Willing to work rotating shifts, including nights
• Marathi/Hindi; English for reports and COAs
