The requirement is for an Agilent CrossLab Silver GC/MS Triple Quad maintenance plan for one 12-month base year at an estimated value of $21,485.52. The plan is only offered annually due to the age of the instrument. It ensures continuous equipment maintenance, minimizes operational disruptions, and supports explosive detection canine training and mission readiness. Because the instrument and components are proprietary to Agilent Technologies, only Agilent-certified engineers are qualified to perform the annual CrossLab Silver preventive maintenance service.
