  Altaire Pharmaceuticals Inc

  Mar 2011 - May 2012

  Analytical Chemist

  Tested raw materials and finished products to ensure they meet United State Pharmacopeia and National Formulary requirements. Testing includes physical and chemical tests such as Gravimetry and Titrimetry, Infrared Spectrophotometry (IR), Ultraviolet Spectrophotometry (UV), water content via Karl Fisher, Refractive Index (RI), Thin Layer Chromatography (TLC), viscosity and pH.• Strengthening the ability to achieve the collection and release of Purified Water and Water for Injection from water tanks each morning. Tested the carbon content of the water using the Total Organic Carbon (TOC) analyzer and Conductivity using a Conductivity meter.• Managed the calibration of the pH meter, Total Organic Carbon analyzer, Infrared Spectrophotometry (IR), and Ultraviolet Spectrophotometry (UV).• Performed basic HPLC using reverse phase techniques and use of Empower software.

  May 2012 - Sept 2019

  Analytical Chemist II

  Tested raw materials and finished products to ensure they meet United States Pharmacopeia and In-House Requirements. Testing includes Tritimetry, Infrared Spectrophotometry (IR), Ultraviolet Spectrophotometry (UV), Mass Spectrophotometry (MS), HPLC, UPLC, Dissolution and Disintegration.• Lead to the sustainability of the company by testing samples via HPLC using reverse phase technique, and samples via UPLC using gradient technique and Empower 3 software. Utilized extensive knowledge of Empower and HPLC troubleshooting techniques allowing for assisting others.• Performed instrument calibration for Ultraviolet Spectrophotometry, HPLC and UPLC systems upon yearly due date. Full calibration report upon completion submitted to and checked by management prior to releasing system back to analysts for use. • Performed full method validation on all over the counter (OTC) samples manufactured by the company, followed with a full summary report and written in house method. Method validation includes accuracy, precision, specificity, detection limit, quantification limit, linearity, and range. Validation performed for identification, assay and dissolution.• Tested research and development samples upon submission to the laboratory. Wrote and validated new in-house methods to comply with the testing of such samples. • Trained all new laboratory employees on good manufacturing practice, laboratory practices, and daily processes for sample testing order and methods. • Assigned work to, and overviewed fellow associates with the help of management to ensure all deadlines are met for the day.• Assisted other chemists with understanding methods and instrumentation problems prior to them reporting to the manager.

  Novartis

  Sept 2019 - Jan 2021

  Quality Control Analyst Senior Associate

  Consulted with management and performed assigned tasks in timely manner with alignment of company needs and time constraints for finished bulk and stability samples. • Suggested recommendations to reassign work and prioritize tasks due to challenges of instrumentation error, sample addition to daily assignment, or other time constraints. • Assisted management in vial/filter study enhancing analytical procedures by 20% where degradation peaks were found to be coming from coating in vials and different types of filters used. Evaluated results to determine new approaches to remove degradation peak arising in testing. • Maintained extensive knowledge on HPLC and UPLC instrumentation and use of Empower software, able to troubleshoot effectively to ensure completion of testing in timely manner.• Performed daily balance calibration, change desiccant, perform weekly walk around to ensure GMP compliance in lab. Assisted in performing monthly audit of other internal labs resulting in a 20% increase in organizational compliance. Show less
