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
CH4, C2H6, C2H2 and CO2. 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 LGD Customer Frontend
available on the Axetris` homepage.
