MEASURING CO2 IN XCDA GAS
REAL-TIME CO2 IMPURITIES MEASUREMENT IN XCDA GAS
APPLICATION
XCDA (extreme clean dry air) is an extremely clean air
type that is widely used in high tech industries. UHP
Purifiers or UHP gas filters are used to purify the gas or
convert lower quality gas into pure quality. Pure XCDA
gas increases the yield, consistency and quality of the
final product.
In the application, it is presumably CO2 contamination
in the XCDA gas for which a CO2 measurement is
performed. Based on the measurement results, it is
judged whether the XCDA gas meets the requirements
of the application, or that appropriate measures must be
taken.
In order to perform this measurement as efficiently as
possible, there was a request for a mobile gas solution
that can measure CO2 pollution in the supply line of the
XCDA gas.
CO2 MEASUREMENT
To measure the CO2 concentrations in the XCDA, a Series
500 handheld monitor has been deployed with a CO2 0 2000 PPM sensor. The gas is guided from the supply via a
plastic hose to the monitor.
A virtually unique solution for gas measurement because
the Series 500 is designed for gas measurements in the
shared room where a pump circulates the outside air
through the sensor head by approximately 0.5 SLMP.
In this application, a plastic hose is connected directly
to the sensor head and via a bypass in the supply of the
XCDA gas. To ensure the accuracy of the measurement
data, a M4.1 diaphragm valve and a SIR100 UHP pressure
regulator are used in the bypass to reduce the pressure
to 0.3 - 0.7 SLPM.

SERIES 500
GAS MONITOR
HANDHELD GAS MONITOR
The series 500 gas monitor has been selected because
of the real-time data logging function. Via the software
supplied, the data can be remotely read and stored in
the monitor (up to 8188 records) and through the online
software. In addition, the monitor is mobile and can be
installed without any on-site installation and if requested
in industrial housing.
The Series 500 monitor uses sensor heads that can
be exchanged via a plug-and-play system. As a result,
there is a minimal downtime during possible switching
between CO2 or other gas sensors.
