CF4 photoacoustic spectroscopy gas analyzer
Testing requirements:
Cleanrooms need to control the level of pollutants. Accurate, reliable, and low-cost AMC control of gaseous molecular pollutants in clean rooms can significantly improve production capacity.

CF4 photoacoustic spectroscopy gas analyzer
Reliable monitoring:
High sensitivity DKG ONE-CF4It can quickly detect pollutants in the production environment. In addition, direct absorption detection can ensure long-term high stability due to its zero background property.


Ultra sensitive optical cantilever microphone
CF4 photoacoustic spectroscopy gas analyzer
Technical application:
DKG ONE-CF4The analyzer is based on ultra sensitive cantilever beam enhanced photoacoustic spectroscopy detection technology, combined with quantum cascade laser (QCL) light source, and operates in CF4The absorption peak of the mid infrared basic spectrum. The combination of these two provides sufficient sensitivity to detect the smallest concentration of CF without delay4Overflow while ensuring ultra-high levels of stability. The recalibration cycle can last for several months or even years, greatly reducing the overall holding cost.
