MultiGas™ 2030 1065-Ready
Engine and vehicle emissions gas analyser
The MultiGas™ 2030 1065-Ready FTIR analyzer combined with the new Engine and Vehicle Application Package was designed to meet Euro VI/Euro 6 and EPA 40 CFR part 1065/1066 requirements for exhaust emission compliance testing. The MKS FTIR analyzer is the worldwide choice for R&D development and certification test labs for light duty (LD) and heavy duty (HD) vehicle and engines as well as catalyst manufacturers.
Different fuel source exhaust emissions are supported not only for raw exhaust measurements but anywhere along the exhaust train.
Key features
- Meets Euro VI and EPA 40 CFR part 1065/1066 requirements
- 5 Hz data acquisition and analysis for fast transient monitoring
- Capable of true 5Hz sampling rates
- High resolution (0.5 cm-1) FTIR reduces interferences from water and CO2, for unbiased, accurate readings
- Gas cell designed for lowest residence time for “sticky” gases and high temperature resistant insulation
- Low volume (200 mL), long path (5.11m) gas cell produces fast response time without compromising detection limits
System Components
The MultiGas 2030 1065-Ready analyzer includes a 5 Hz acquisition FTIR spectrometer coupled with a patented 5.11m high-optical-throughput, low volume (200 mL) gas sampling cell. The gas cell was redesigned for increased ruggedness and corrosion resistance. It can handle up to 100 LPM, providing a true 5 Hz sampling rate along with the 5 Hz data acquisition rate. The 3/8” inlet and outlet plumbing reduces backpressure and noise, enabling flows from 0.5 LPM up to 100 LPM while providing sensitivity that is unbeaten in the industry. The new cell has welded inlet and outlet which are more durable and resistant to leaks in cases where the gas cell needs to be cleaned frequently. The cell also includes improved insulation which ensures that the gas remains at correct temperature and that the instrument’s internal components do not overheat.
At a flow rate of 60 LPM the refresh rate of the gas sample is actually 5 Hz (gas refresh time of 0.2 sec) – providing speed and sensitivity unmatched by any other analyzer.
High Time Resolution
The resolution of gas profiles of the MultiGas 2030 1065-Ready has indeed been observed to exceed that of instruments running at 10 Hz and has been attributed to differences in flow rates where the 10 Hz analyzers are suffering from under sampling (low flow rate).
The MultiGas 2030 1065-Ready not only operates at a high sampling and acquisition rate but does so without sacrificing resolution. The analyzer maintains its excellent performance capabilities using high resolution (0.5 cm-1) spectra for optimum quantification of components that have high interference with water and CO2. The figure illustrates the interference effect by showing the severe overlap between NO and H2O peaks. However, due to the high resolution of the spectrum, the NO peaks can be clearly separated from the H2O peaks, which allow accurate NO quantification.
Engine and Vehicle Application Package
Using the Engine and Vehicle Application Package, over twenty gases can be quantified simultaneously at 5 Hz with detection limits of 1 ppm or less for most components. The Application Package features multi-point calibration curves that provide large dynamic measurement ranges from low ppm to % level. This ready-to-use method offers the ability to perform analysis when CO2 and H2O levels up to 20% with no user input required. The Application Package includes 1065-compliant calibrations for many species such as N2O, NH3, CH4 and others, and is applicable for many different fuels. The Engine and Vehicle Application Package is for gas samples running at 1 atm pressure and 191°C and new 113°C calibrations are also available for use in worldwide markets.
The calibrations included in the Engine and Vehicle Application Package are applicable to all MultiGas 2030 1065-Ready analyzers because each instrument is tuned to extremely tight specifications, which allows a calibration generated on one instrument to be used on any other instrument without modification. A one-time or a regular span can however also be used for the highest accuracy requirements.
