David will train on the GC methods in 2017.
Andrea Castillo Client Services / Analytical Chemist
Ms. Castillo joined Caliber Analytical Services as a part time lab technician in the Spring of 2008, her junior year at Towson University. After completing her BS degree in Chemistry with high honors in May 2009, we were extremely pleased to have Andrea join our staff as a full time chemist. She has mastered all of the organic extraction procedures we employ, and is currently responsible for the analyses of Diesel Range Organics by GC-FID, and Pesticides/PCBs and Herbicides by GC-ECD. She will continue to cross-train on the GC-MS methods performed at CAS, and provide the backup that will ensure the uninterrupted quality services our customers have come to depend on.
Andrea was rewarded for her research on phosphanyl(organyl) boranes (POBs) with a trip to Capitol Hill to present a research poster for the 2009 Council of Undergraduate Research.
