Safety Air Monitoring and Analytical Referee System (SAMARS) Gas Chromatograph (GC)

Procure two GC instruments with the following specifications:

• 
  
  
  
  • Flame Photometric Detector (FPD); one instrument with phosphorous optical filter, one instrument with sulfur optical filter
  
  
  • Chromatographic columns: one instrument DB-1701 phase and one instrument DB-210 phase column;
  
  
  • Air sampling pre-concentrator trap capability with flow rate through the trap of at least 500 mL/min
  
  
  • External mass flow controller, ability to capture the flow meter readings
  
  
  • Oven programmable from ambient to 400℃
  
  
  • Cycle time from injection to injection of 15 minutes or less
  
  
  • Visible and audible alarms for system faults and sample concentration detections
  
  
  • Quick change trap assembly, flow rate of 500 mL/min with ability to change the preconcentrator tube in approximately 1 minute
  
  
  • Onboard integration engine with graphical use interface. Ability to operate the instrument, calibrate, troubleshoot, analyze samples, etc. from the user interface. Visual readouts displayed of set points and measurements such as: sample flow, temperatures, pressures, concentrations, injection types, valve status, voltage, etc.
  
  
  • Data logging. Ability to capture instrument set points and measured values such as: flow, temperatures, pressures, calibration, concentration, injection type – calibration, service, sample, etc. Data captured locally with the ability to retrieve and use for other reporting or calculating of sample data.
  
  
  • Automatic calibration feature. Calibration of the instrument using an averaged single point or multi-point calibration curve. Capable of calibrating and obtaining sample concentrations using the onboard integration engine, and values displayed on the graphical user interface.
  
  
  • Heated exhaust to prevent expulsion of water. Detector exhaust must expel water in gas/vapor form elimination water drip from the instrument detector.
  
  
  • Sample bypass capability. Ability for continuous sample flow at inlet in a bypass state. A minimum flow of 500 mL/min required for bypass capability.
  
  
  • GC approximate dimensions - 17” x 11” x 8.5” (width x height x depth)
  
  
  • Instrument weight approximately 25 pounds
