Analyzer arrangement
GasEye Cross Duct SG mechanical assembly
The GasEye Cross Duct SG (Single Gas) analyzer consists of a pair of cross-duct
sensors - a central unit with transmitter and a receiver unit. The central unit emits
laser radiation directly through the process containing the constituents of interest. The
receiver unit collects the radiation on the other side of the process duct. The receiver
unit is connected to the transmitter unit by means of a hybrid loop cable (included).
The GasEye Cross Duct utilizes an internal in-line reference gas cell or a process gas
(e.g. H2O) for real time verification of the calibration status.

Functional description
Principle of operation
GasEye Cross Duct is a laser analyzer that utilizes tunable diode laser (TDL)
absorption spectroscopy. The central unit sends a laser light through the process
which is detected by the receiver unit mounted on the opposite side of the process.
When a gas of interest is present in this process, it will absorb the laser light. The
optical power detected in the receiver unit will depend on the concentration of the gas,
temperature, pressure and optical pathlength according to Lambert’s Beer law. Thus
in order to determine the gas concentration, the analyzer requires information
regarding temperature, pressure and optical pathlength. Temperature and pressure
signals can be provided by analog inputs, via industrial communication protocols or
as manual values via Webserver or HMI. Pathlength needs to be provided by the
user via HMI or Webserver.
In the GasEye Cross duct analyzer, the laser wavelength is specifically chosen to
match the fingerprint region of the particular gas of interest and is being continuously
scanned over the absorption lines(s). Since full spectral information is recovered with
very high spectral resolution the analyzer remains immune to foreign gas broadening
and is immune to cross-interferences from dust and any other gas constituents in the
process.
GasEye cross duct by design can operate in several wavelength regions from near
infrared to Mid-Infrared.

Calibration and calibration certificate
The analyzer is calibrated using certified gas sample in the factory. One of the key
parameters of the analyzer is its limit of detection (LOD) which determines the lowest
measurable concentration. This quantity is estimated for each application and is
determined for each device before shipping to our customers. For every GasEYE
analyzer we determine the limit of detection during a 12-hour cycle in a climate
chamber. The analyzer is placed on a test gas cell and a zero sample is introduced.
A zero sample is either nitrogen or dry air to purge out the constituent of interest. The
climate chamber temperature is then varied between
-20°C to +55°C and the concentration signal is logged, as well as other important
analyzer parameters. Based on the concentration reading during the temperature
cycle the limit of detection is calculated using the following equation:
𝐿𝑂𝐷 = 2 ∗ 𝑠𝑡𝑎𝑛𝑑𝑎𝑟𝑑 𝑑𝑒𝑣𝑖𝑎𝑡𝑖𝑜𝑛(𝑔𝑎𝑠 𝑐𝑜𝑛𝑐𝑒𝑛𝑡𝑟𝑎𝑡𝑖𝑜𝑛)
Limit of detection is usually quantified in ppm x meter units. This allows to easily
recalculate the limit of detection for arbitrary path length. For example: Limit of
detection for standard carbon monoxide application at room temperature is LOD 0.2
ppm x m. If the process path length is 2.5 meters the actual limit of detection at this
distance will be:
𝐿𝑂𝐷 (@ 2.5 𝑚𝑒𝑡𝑒𝑟𝑠)= 𝐿𝑂𝐷
𝑃𝑟𝑜𝑐𝑒𝑠𝑠 𝑝𝑎𝑡ℎ 𝑙𝑒𝑛𝑔𝑡ℎ = 0.2 𝑝𝑝𝑚 𝑥 𝑚
2.5 𝑚 = 0.08 𝑝𝑝𝑚
Before shipment, each analyzer is accompanied with individual calibration certificate,
see Figure 8, where all calibration and performance information are given.
