3.1 Infrared (IR) and Ultraviolet (UV) Measurement

modulated with 4 and 5 times the basic re-
volution frequency, respectively. As a result,
the proof peak process is integrated into the
measurement information, in contrast to being
articially inserted in the measurement signal.
Frequency ltering separates the sum signal
into measurement and reference signal ( Fig.
3-1). This results in a permanently referenced
signal by dividing the integrated reference
level by the integrated measurement level for
each revolution.
Therefore the IntrinzX technology provides
many outstanding features:
• High dynamic measurement ranges (e.g.
0-200 to 50,000 ppm CO), which cannot
be obtained with standard photometric
technologies
• Reduced temperature dependency
•
High sensitivity for lowest measuring
ranges
This leads to cost saving effects for the cu-
stomer:
• Fewer number of benches & cells
•
Easier eld repair and replacement of parts
•
Easy adjustment of low measuring ranges
in the eld
• Reduced maintenance
• Extended span calibration intervals
• Minimized demand for test gases
Due to the inherent correlation between refe-
rence and measurement side, span calibration
can often be achieved by zero calibration.
The above listed IntrinzX features offer a
high degree of exibility with regards to ap-
plications:
•
One bench enables measurements of low
& high ranges
•
Low & high concentration in raw and clean
gases
• Small and large ranges before and after
scrubbers
•
Measurement of carbon bed breakthrough
/ catalyst efciency
•
Mobile measurements at different sampling
points / locations
•
Easy adaption to different applications
(universities, laboratories)
• Supports automotive engine testing
• Benches to be used in TOC applications
for measurements of low and high carbon
