The Model T200UP uses a UV-based photolytic converter to provide
"true" trace level measurements of NO
. The patented technology allows
2
for speciation of NO
. As the sample gas passes through the converter
2
chamber it is exposed to blue light at specific wavelengths (350-420 nm)
from an array of ultraviolet light-emitting diodes (LEDs). This selectively
converts the NO
to NO with negligible radiant heating or interference
2
from other gases. The T200 operation manual section, Principles of
Operation, details the Chemiluminescent measurement as well as other
components.
