Quality Control (QC) Wet Lab Chemist — Job Profile

Overview

A QC wet lab chemist ensures raw materials, in-process samples, and finished products meet predefined specifications through laboratory testing, documentation, and compliance with quality and safety systems. The role is common in pharmaceuticals, specialty chemicals manufacturing.
Core Responsibilities
Perform routine and non-routine wet chemistry tests: titrations (acid-base, redox, complexometric), pH, conductivity, viscosity, moisture (Karl Fischer), chloride/sulfate by argentometric/gravimetric, hardness, ash, loss on drying, refractive index, melting point, etc.
Conduct instrumental analyses commonly used alongside wet chemistry: UV-Vis spectrophotometry, FTIR, TOC; often exposure to pharma/chemicals.
Sample handling: receipt, identification, and representative sampling of raw materials, intermediates, finished product, stability, and environmental/utility samples (e.g., purified water).
Method execution and verification: follow pharmacopeial (IP, USP, BP, EP)



and validated in-house methods; assist in method transfer and robustness checks.
Data integrity and documentation: contemporaneous recording in controlled notebooks/eLIMS, calculations, CoA generation, deviations/OOS/OOT investigations, and change controls.
Equipment management: daily checks, calibrations, basic troubleshooting, and preventive maintenance coordination for balances, pH meters, KF titrators, burettes, ovens, muffle furnaces, viscometers, UV-Vis, FTIR.
Quality systems: adhere to GLP, GDP, cGMP; participate in internal/external audits; implement CAPA and continuous improvement.
Safety and housekeeping: chemical hygiene, PPE, MSDS/SDS use, waste segregation, fume hood practices, 5S.
Cross-functional support: interface with production, QA, R&D;/ADL for investigations, specification setting, and process improvements.
Typical Day in the Lab
Calibrate pH meter/balances; standardize titrants (e.g., NaOH, HCl, AgNO3).
