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).
