Micro Gas Chromatograph Specifications ~1.pdf

Specifications for Portable micro-Gas Chromatograph Agilent Brand Name or Equivalent

• The instrument specifications are for a micro-Gas Chromatograph (GC) for the detection of pennanent gases and light hydrocarbons.

• The GC must be fast enough to run 20 samples per hour and rugged enough to sustain this throughput continuously.

• The system should include the GC, power supply, a computer, software, all connections, setup of GC, and training of personnel.

• The GC unit should be linked to a computer for data analysis and storage.

• For field analysis of samples a laptop computer is required

• The Gas chromatograph needs to be compact enough to be easily portable

• The GC must also be able to be used in the field running off of a converter from a vehicle for electric power (not supplied) and individual portable gas cylinders (not supplied)

• Malfunctioning parts within the GC must be able to be quickly and easily be replaced or repaired independently of other components within each channel.

• Gas Chromatograph specifications:

o Software selectable injection volumes of 1 µL to 10 µL o Each column is backflush capable o Oven capable of temperatures of30 to 180 degrees Celsius o Dual-channel four-filament micro thermal conductivity detector o Linear range of five orders of magnitude or greater o Less than one percent RSD repeatability o Minimum of twenty samples per hour throughput o Single injection for the determination of all compounds o Capable of injection by internal pump or by luer-lock syringe o Inlet connections for two external gas supplies o Individual replaceable components (detector, injector, column, etc.) within each of the four channels o Simultaneous analysis of four channels:

• Compounds oflnterest and Detection Ranges required by the instrument:

o Methane (l0ppm/100%) o Carbon monoxide (lOppm/10%) o Carbon dioxide (lOppm/100%) o Oxygen (l00ppm/30%) o Nitrogen (l0ppm/100%) o Hydrogen (l0ppm/10%) o Ethane (l0ppm/15%) o Ethylene (lOppm/10%) o Acetylene (l0ppm/10%) o Propane ( l0ppm/10%) o Propylene (l0ppm/10%) o Argon (by calculation) (100ppm/S%)

• The main power supply for the instrument must be 110 volt AC, 60 Hz with a maximum 2SOW power consumption

• A computer must be includt:d and should control all GC functions, data analysis, and storage

• Open Lab CDS software is required to run the GC to expedite emergency analysis

• GC software must be compatible with Microsoft Office capable of exporting to Excel

• The GC must be able to be transported by simply disconnecting the power and gas supply

(no internal disassembly or securing)

• The GC must weigh less than 40 lbs and have a maximum size of 1.5 cubic feet
