Horiba, a supplier of measurement and test systems for the automotive industry, has again expanded its range of engine exhaust analysers with two new products, the FTX-ONE-CL and the FTX-ONE-RS. Both models use Fourier transform infrared spectroscopy (FTIR) to continuously measure the gas concentration of up to 28 components contained in the exhaust gas, including carbon dioxide, nitrogen oxide, formaldehyde and ammonia. With this, the company wants to meet the increasing demands on measurement technology in the wake of stricter exhaust gas regulations worldwide.

The FTX-ONE-CL FTIR engine exhaust analyser now enables continuous dilute bag measurements of extremely low concentrations thanks to a newly developed high performance optical cell from Horiba with a long optical path. Its compact design, which is about half the size of other standard analysers, makes it very space-saving. For dilute exhaust gas measurements, the FTX-ONE-CL can be used either as a stand-alone analyser or as an integrated product with the MEXA CVS system. The device is intended, among other things, for tests in the context of vehicle development. For example, it can be used to measure non-methane organic gases (NMOG) from natural gas vehicles and nitrous oxide (N2O). Both components are regulated by the US Environmental Protection Agency (EPA) in its current emission standards (LDV Tier 3).

The FTX-ONE-RS FTIR engine exhaust analyser ensures dynamic and flexible measurement of raw exhaust emissions due to its powerful compact Horiba high performance gas cell. In addition to the FTIR analyser as used in the FTX-ONE-CS, the FTX-ONE-RS offers the option of adding a heated flame ionisation detector (HFID) to measure total hydrocarbons (THC) and/or a magneto-pneumatic analyser (MPA) to detect oxygen (O2).
