3000 Micro GC Operating Manual
Chapter 1
Introduction
This operating manual describes the use and maintenance of the INFICON 3000
Micro Gas Chromatograph (GC).
3000 Micro GC can be used to analyze alternative fuels such as natural gas,
syngas, biogas, and landfill gas. Additional applications include: refinery gases,
mine gas, furnace gas, custody transfer, well logging, environmental screening,
storage tank analysis, scrubber analyses, and monitoring volatile organic
compounds (VOC).
3000 Micro GC in combination with EZ IQ data handling and instrument control
software provides a comprehensive, easy-to-use gas analysis system.
1.1 About the Instrument
3000 Micro GC self-contained GC modules consist of an injector using
Microelectromechanical Systems (MEMS) technology, analytical and reference
columns, electronic pressure control, and a thermal conductivity detector (TCD)
also using MEMS technology.
NOTE: When installed in a 3000 Micro GC chassis, a module is referred to as a
channel. When standalone, it is referred to as a module.
Routine replacement of parts such as septa, ferrules, or columns is not required.
This eliminates the need for frequent leak testing.
Samples are introduced through a 1/16 in. Swagelok ® connection to inlet(s) on the
3000 Micro GC front panel. This design eliminates the need for traditional
hypodermic syringe injection through septa. The inlet pressure can be nearly
atmospheric because an internal vacuum pump connected to the column exit
eliminates column back pressure. See
Table 1-1 for a summary of external
connections.
