Hiring Chemist with 2 to 3 years of experience specializes in the routine operation, basic calibration, and troubleshooting of high-end analytical equipment.

Core Focus: Advanced chromatographic and mass spectrometric analysis (GC, GC-MS, GC-MS/MS, HPLC)

Education: Master’s Degree in Chemistry, Analytical Chemistry.

Key Responsibilities

1. Instrument Operation & Testing
- Execute sample analysis using Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC).
- Perform trace-level quantification using hyphenated techniques like GC-MS and GC-MS/MS for residual solvents, pesticides, or impurities.
- Prepare samples using techniques like liquid-liquid extraction, Solid-Phase Extraction (SPE), and headspace sampling.

2. Calibration & Maintenance
- Conduct routine calibration of HPLC and GC systems to ensure instrument compliance.
- Perform basic maintenance, including replacing GC septa, liners, syringe needles, HPLC columns, guard columns, and mobile phase filters.
- Execute system suitability tests (SST)



prior to sample batch execution to verify instrument performance. [1, 2, 3, 4]

3. Data Analysis & Documentation
- Process raw chromatographic data using software like Empower, Chromeleon, or LabSolutions.
- Review peak integrations, interpret mass spectra fragments, and calculate final concentrations against standards.
- Maintain meticulous documentation of raw data, logbooks, and analyst worksheets in line with Positive Laboratory Practices (GLP).

4. Compliance & Troubleshooting
- Investigate Out of Specification (OOS) or Out of Trend (OOT) results under senior supervision.
- Identify system errors like baseline drift, pressure fluctuations, or ghost peaks, and implement initial corrective actions.
- Adhere to safety, data integrity, and regulatory protocols (such as USFDA, MHRA, or NABL/ISO 17025 depending on the industry).

Required Technical Skills
- HPLC/GC: Proficiency in standard isocratic and gradient runs, injection mechanisms, and standard
