Description

Specifications include, but are not limited to: 2.2.1 The gas chromatograph shall be fully automatic with an oven design that allows easy access to columns. 2.2.2 The gas chromatograph’s column oven shall: a. Cool from 300 degrees C to 50 degrees C in less than five (5) minutes (50 degrees decrease per minute); b. Have a programmable temperature to a minimum 250 degrees C/minute; c. Have an oven temperature reaching a minimum 450 degrees C; and d. Have a programming rate range of approximately -400 to 400 KPa/minute. 2.2.3 The gas chromatograph must be split/splitless capillary injection design equipped with an autosampler allowing for various injection speeds and must use columns from 0.1 to 0.75 mm inter-diameter in split and splitless modes. 2.2.4 The gas chromatograph must have a minimum 80 sample positions and reproducibility of injection <0.5% RSD for 1 uL injections. 2.2.5 The gas chromatograph must have pressure and flow program ramps with a flow control rate of up to 1,200 ml/minute. 2.2.6 The mass spectrometer must use quadrupole technology, be fully serviceable, equipped with solid molybdenum (metallic) alloy rods (or equal), and designed with a pre-filter system situated before the main quadrupole rods. The unit must have an easily accessible quadrupole. The mass spectrometer shall have a linear dynamic range of at least 106 in scan mode. The system must have pre-quads with 60 khz ripple applied for maximum ion transfer through the RF filter and minimize the contamination of the main quads allowing longer operation without maintenance. 2.2.7 The mass spectrometer must have an operating mass range within the guideline range from 1.5 m/z to 1,090 m/z and it must have an EI signal-to-noise ratio of >200:1 for 1pg OFN in full scan mode, and signal-to- notice ratio of >160:1 RMS for 100fg OFN at 272 m/z in SIM mode. 2.2.8 The mass spectrometer must be a dual filament system that allows the user to change the filament without removing the quadrupole assembly. The ion chamber must be located at the front of the instrument for easy maintenance. The filaments must have two rhenium coil filaments or comparable coil filaments, with automatic on/off controls to prevent filament damage.
