Overview Natural resource scarcity is creating higher demand for faster

and more reliable analyzers. A new microchip GC technology

that includes an injection system, column and detector in a

unique compact cartridge was developed by Thermo Scientific

for rapid analysis of natural gas composition. This micro GC

increases analytical productivity by accurately analyzing the

calorific value of natural gas, providing reliable results in

seconds. It also reduces maintenance costs, consumes less gas

and can be used both inside laboratories and on-line.

Exchangeable column cartridges can be easily installed for

flexible configuration and ease of use.

A temperature control allows the micro GC columns to be

programmed with a speed of 240°C per minute for the analysis

of a wider range of components. An integrated stream selector

for auto calibration provides on-line, reliable analytical results.

The micro GC has dedicated instrument control and data

handling software to run on a system, generating rapid results

from the time the micro GC is installed. Reporting is available in

compliance with current ISO, ASTM and GPA methods.
