natural gas analysis in less than 1 minute by micro gc with
TRANSCRIPT
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.
