The Transportation Security Administration (TSA), through its Chemistry & Explosives Branch, requires an Agilent CrossLab Silver preventative maintenance service agreement for the Agilent Gas Chromatography Mass Spectrometer (GC/MS) 7250 Quadrupole Time of Flight (QTOF) System used in the Chemistry Lab. The agreement would cover a 12-month base year of service with up to four additional 12-month option years. This maintenance is essential to keep the equipment properly calibrated and operating at optimal standards for accurate research and analysis. The resulting data affects how Canine Explosives Training Aids (CETA) are prepared, configured, and packaged.
