• Perform wet chemistry and general laboratory product testing in the QC Lab, including sieve analysis, thin layer chromatography, and loss on drying using vacuum ovens.
• Conduct high-throughput testing, completing approximately 12 to 16 tests per day, while managing weighing and sample preparation for materials ranging from 50 mg to 1 g.
• Accurately document all product testing results in a lab notebook, adhering to GMP and GDP documentation standards.
• Receive and log feed samples in the Feed Lab, ensuring proper tracking and chain of custody.
• Carry out sample preparation for feed analysis, including grinding, weighing, and solution preparation.
• Analyze customer feed samples using HPLC, column chromatography, and UV-Vis techniques in accordance with established procedures.
• Record feed analysis results following GMP guidelines and report final results to leadership in a clear and timely manner.
• Manage a typical feed sample load of approximately 16 samples per day, with flexibility to handle increased volumes during busier periods such as late summer.
• Follow all established procedures, systems, and methods without making unapproved process changes, ensuring consistency and compliance.
• Collaborate effectively with both a small team in the Feed Lab and a larger QC team, contributing to a positive and cooperative work environment.
