Optimization of Catalyst Efficiency through in-situ Laser LDS 6
Protecting the environment from harmful emissions from
internal combustion engines requires an effective method
either to avoid them, or to convert them into innocuous
gases. Since recently any newly registered vehicle is
required to meet the EURO VI emission standard. Consequently, there is a permanent requirement for engine
developers to ensure the denitrification of the engine
exhaust and thus reduce the amount of harmful emissions.
The LDS 6 has been approved for the "Laser
diode spectrometer (LDS)" measurement principle according to the EURO VI standard (appendix 582/2011/EC). It is
perfectly suited for the requirements of the standard,
because it determines the ammonia concentration quickly
and easily, while it can also be checked according to the
EURO VI standard without the need to use external test
gases. This eliminates the need for time-consuming and
costly linearity checks by the user.
Faster analysis than with extractive analytical instruments ensure most effi cient optimization
The in-situ approach allows representative NH3 measurements without cross interference
Fast and easy linearity checks according to EURO VI
standard thanks to ten-cell test kit
Up to three measurement points can be handled with
only one analyzer
No gas sampling/conditioning is necessary, the gas is
measured in situ
Highest reliability and lowest cost of ownership: no
consumable parts, very low maintenance, no calibration
necessary
No cross interferences due to highly specifi c single line
absorption measurement
The maintenance is reduced to the cleaning of the sensor
windows. No optical realignment is necessary after cleaning.
