Performed assay, impurity & physical testing on finished products and raw materials using an array of techniques such as Karl Fischer, UV-Vis, IR and UPLC/HPLC/LCMS systems to quantitate the amount of API or impurities within products that are produced on site or to be used in production. Used Empower and NuGenesis software to process data, set-up specific instrument parameters for testing and edit processing methods to ensure proper integration of data. Lead laboratory improvement projects such as the installation and verification of NuGenesis software and qualification with several 3rd party groups, as well as the implementation of maintenance trackers and data trackers for everyday laboratory usage. Main chemist responsible for all repairs and preventative maintenance on all UPLC/HPLC systems on site to ensure systems are in optimal condition in addition to troubleshooting issues that arose when setting up UPLC/HPLC systems for use. Performed data review on finished chromatogram reports and specification sheets to ensure that all data is reported correctly and accurately according to SOPs.
