Quality Control Lab Technician

Quality Control Lab Technician

The Quality Control Lab Technician performs a full range of laboratory testing to ensure products meet established quality specifications. This role uses advanced analytical instrumentation and wet chemistry techniques to test raw materials, in-process samples, and finished goods, while accurately documenting results and supporting continuous quality improvement within a chemical manufacturing environment.

Responsibilities

• Perform quality control testing on raw materials, in-process samples, and finished products to verify compliance with established specifications.
• Operate and maintain Gas Chromatography (GC) systems to analyze chemical samples according to defined methods.
• Use High Performance Liquid Chromatography (HPLC) to perform detailed quantitative and qualitative analysis.
• Conduct analyses using UV-Visible spectrophotometers to measure optical absorption and related properties.
• Perform Infra-red (IR) spectroscopy and FTIR analyses to identify and characterize chemical compounds.
• Carry out pH analysis, titrations, and other wet chemistry methods to support routine and special testing.
• Execute residue after evaporation testing, fluorescence testing, viscosity measurements, and other relevant QC analyses.
• Determine key analytical parameters as required by test methods and specifications.
• Set up daily standards, perform daily Karl Fischer (KF) calibrations, and prepare special purpose laboratory equipment for testing.
• Plan and prioritize the sequence of testing for incoming samples to meet turnaround time and production needs.
• Review, interpret, and summarize analytical data, ensuring results are accurate, reliable, and complete.
• Record all analytical results using good documentation practices and in accordance with laboratory procedures.
• Communicate effectively with the QC team and cross-functional teams to share results, raise issues, and support production and quality decisions.
• Contribute actively to the quality management efforts within the organization by following established quality procedures and suggesting improvements where appropriate.
• Perform other laboratory and quality-related duties as assigned to support overall departmental goals.

Essential Skills

• Hands-on experience or strong academic background in analytical chemistry techniques, including Gas Chromatography (GC) and High Performance Liquid Chromatography (HPLC).
• Ability to operate and interpret results from UV-Visible and Infra-red (IR) spectrophotometers, including FTIR.
• Proficiency with wet chemistry methods such as titration, pH analysis, and related quantitative techniques.
• Experience or training in quality control testing for raw materials, in-process samples, and finished goods in a chemical or related laboratory setting.
• Strong attention to detail with the ability to follow written procedures, test methods, and documentation standards precisely.
• Capability to review, interpret, and summarize analytical data accurately.
• Comfort working independently for extended periods while maintaining productivity and accuracy.
• Effective communication skills to collaborate with QC colleagues and cross-functional teams.
• Basic understanding of quality assurance and quality control principles in a laboratory or chemical manufacturing environment.

Additional Skills & Qualifications

• Preferred:
  Bachelor's degree in a hard science, with a strong preference for Chemistry or Biochemistry.
• Other qualifying degrees may include Biology, Microbiology, or Environmental Science, provided there is meaningful chemistry laboratory experience from school.
• Entry-level candidates may qualify if they have completed an internship or have strong hands-on chemistry lab coursework.
• Candidates with an associate degree in Science and at least 1 year of industry chemistry experience are also suitable.
• Candidates with a high school diploma and 2–3 years of recent industry experience in a chemistry laboratory setting will be considered.
• Interest in quality assurance, formulations, or broader QA activities is beneficial for future growth.
• Experience in chemical manufacturing, raw material testing, in-process analysis, and finished goods testing is a plus.
