MKS MultiGas™ 2030 HS High Speed Gas Analyzer

5 Hz Monitoring Capability in Automobile, Diesel and Catalyst Emissions Measurements

Monitoring traditional (CO, CO₂, NO, NO₂, SO₂, O₂, HC, and H₂O) and nontraditional (NH₃ & N₂O) combustion gases in less than a second is a necessity for automotive, diesel and catalyst manufacturers. Currently, there are limited analytical techniques available that can monitor these gas species in this time frame and at the level necessary to be useful.

New Federal Government emissions regulations for calendar years 2007 and 2010 are forcing manufacturers to better understand their combustion and emission reduction processes. Many of the traditional gases can now be monitored at 5 Hz using conventional CEM analyzers. However, the newer processes generate species such as ammonia (NH₃) and nitrous oxide (N₂O) that are not currently monitored by traditional analyzers. New chemistries and methodologies used to meet the new federal standards such as Low NOx Traps require the collection of transient analytical data to optimize the emission/combustion reduction processes. Because N₂O and NH₃ still require new methodologies for monitoring, manufacturers are demanding analytical equipment that can monitor both the traditional and non-traditional gases at frequencies as high as 5 Hz.

Use of FTIR gas analyzers is an excellent solution to this problem since they can measure most any gas generated by combustion processes. With advances in computer technology, software, instrument calibration, electronics, and instrument design, FTIR gas analyzers from MKS can deliver measurements with high sensitivity at the fastest speeds achievable today.

The MKS MultiGas™ 2030 HS high speed analyzer is capable of simultaneously monitoring 20+ traditional and non-traditional combustion gases at up to 5 measurements per second. The system’s patented, fast-scanning FTIR provides high resolution (0.5 cm^-1) data even at 5 Hz. Detection limits are typically below 1 ppm at 5 Hz. This high speed analyzer can speciate NOx, hydrocarbons, as well as quantify NH₃ and N₂O levels. Combustion exhaust gases flow through heated gas lines to the 200 ml gas cell (calibrated at both 150°C and 191°C) eliminating condensation, while flow rates up to and above 100 L per minute prevent diffusion and measurement delay. The small volume gas cell has an optical path length of 5.11 meters, resulting in excellent analytical sensitivity.
