1 GENERAL USER INFORMATION
1.1 LGD Compact introduction
Axetris’ laser gas detector (LGD), “LGD Compact”, is a system for the continuous monitoring of gases such
as CH
4
, C2H6, C2H2 and CO
2
. Based on state-of-the-art
Tunable Diode Laser Spectrometry
(TDLS), the
system has a very high selectivity to the target gas and features an innovative, patented measurement
principle without the need for a physical reference channel. The system is based on a flow-through cell for
extractive gas measurements at ambient temperature.
Typically
one
system
monitors
one
gas.
Concentration ranges are customer-specific and can
cover 0-100 ppm just as well as percentage range,
depending on the gas and measurement conditions.
Calibration is factory set according to customer
application requirements - generally re-calibration is
not necessary except in cases where the customer
application conditions differ significantly from the
feasible factory calibration conditions. Offset and
span adjustments can be performed on a
maintenance basis and might be necessary due to
systematic differences in calibration and gas delivery
equipment. This can be done via the Graphic User
Interface (GUI) provided with the system software.
