Component Repair and Calibration

Che cosa richiede la stazione appaltante

Notice of Intent The Centers for Disease Control and Prevention intends to award a sole source firm fixed price purchase order to TSI Incorporated 500 Cardigan Road Shoreview, MN 55126 (CAGE Code: 24575) for the purchase of repair and calibration services for Government owned equipment. Only the manufacturer (TSI Inc.) can repair and calibrate the Aerodynamic Particle Sizer because proprietary models must be adjusted for the calibration, proprietary knowledge of internal flow regulators is needed for the repair, and unique access to instrument components that are located behind embedded electronics is required. Alternative service providers are not available because proprietary information on the instrument operating model and flow regulation system is required. Description TCI shall repair and calibrate 3 Aerodynamic Particle Sizers with an expected turnaround of 21 days. Upon receipt of instruments, TSI Inc. shall bring the 3 Aerodynamic Particle Sizers to a calibration flow rate of 5 liters per minute (lpm) (1 lpm for sample + 4 lpm for sheath) and maintain the calibration flow rate, even with a pressure drop of up to 50 inH20 at the inlet by adjusting microprocessor controlled volumetric flow control, barometric pressure correction, and separate pumps for sheath and total flows, to enable the Aerodynamic Particle Sizers to operate under a wide range of conditions and still maintain calibration. TSI Inc. shall also calibrate the 3 Aerodynamic Particle sizers for precise and accurate numbersize distributions for 0.37 to 20 micrometers aerodynamic diameter using a time-of-flight technique, and a patented, double-crest optical system to detect the occurrence of particle coincidence (when more than one particle is in the detection area) and to identify poor signals near the instrument’s lower detection threshold. The Government will provide the following components for repair and calibration: 1. Aerodynamic Particle Sizer-S/N 1169 2. Aerodynamic Particle Sizer-S/N 1203 3. Aerodynamic Particle Sizer-S/N 72321006
