Horiba is in Chennai to share how its new IRLAM analyzer can measure gases accurately in real time, which was previously difficult to do with conventional infrared gas analysis technology.
The company’s marketing representative, Bhavesh Ambre, explained, “Pollutants such as CO2 and CO can be measured with conventional analyzers, but the new regulatory pollutants added in the latest regulations, such as N2O, NH3 and HCHO are difficult to measure due to low sensitivity and high interference with other gas components. Molecules have the property of absorbing infrared light of specific wavelengths.
“By using infrared spectrometry, many of the pollutants found in vehicle emissions, such as CO2 and NOX, can be measured. With the world moving toward carbon neutrality, we need techniques to measure maximum pollution by minimizing size with highly responsive equipment. The advantages of the IRLAM are high sensitivity and low interference. In addition, IRLAM can be used with PEMS type, as it can be miniaturized and has robustness against temperature and vibrations. Using IRLAM both in the laboratory and on board will highly correlated data to improve the efficiency of R&D of vehicles, engines and catalysts.”
According to Ambre, IRLAM is the company’s new core analysis technology. He explained, “The calculation algorithm of IRLAM is an original one patented by Horiba; its key component laser, QCL, is also made in-house. We know everything from the characteristics of the parts to the characteristics of the computing. It is a technology that other companies cannot compete with.”
Ambre said that Horiba’s expertise is well suited to developing and advancing this technology: “The world’s first QCL analyzers were sold by Horiba in the automotive market in 2011. Horiba has produced versatile technologies, NDIR and FTIR, from in-house parts for many decades rather than buying them from other suppliers. We have released the IRLAM by developing a longer and greater amount of in-depth technology experience than any competitor.
“FTIR is vulnerable to vibration and has a weakness in durability because it contains moving parts inside. This characteristic would be a disadvantage for PEMS analyzers in principle. In addition, while FTIR applies corrections to results to remove noise and increase sensitivity frequently, IRLAM allows high-sensitivity measurements without correction. We believe that obtaining unprocessed raw measurement results is advantageous in analyzing data.
“Horiba choose Automotive Testing Expo India to present its next-generation infrared gas analysis technology as India’s shift to alternative fuels such as H2 ICE and E20 is expected to be rapid, making it one of the regions in the world most focused on clean energy research and development. Alternative fuel exhaust gas contains more water than conventional gasoline or diesel exhaust gas. The water can be the interference component for many analyzers, but IRLAM is less susceptible to water. The purpose of our exhibit is to raise awareness of advanced technologies such as IRLAM and FTIR technology for that day in the future when the emissions of alternative fuels must be measured with high accuracy.”
