The optical hardware used in IRLAM is developed, designed and manufactured in-house by HORIBA.
In 2021, HORIBA succeeded in developing a new and proprietary method of Infrared Laser Absorption Modulation (IRLAM™) and putting it into practical use.
IRLAM enables real-time measurement of gases that were difficult to measure with conventional infrared gas analysis technology, due to insufficient sensitivity and interference effects (effects of coexisting gases other than the gas to be measured).
IRLAM is an evolution of the infrared gas analysis technology that HORIBA has refined over the years, and positions this technology, which can achieve High Sensitivity, Low Interference, Compact size, and High Reliability, as a new core analysis technology for HORIBA.
The features of IRLAM are realized by three of HORIBA's proprietary technologies: Quantum Cascade Laser (QCL), Herriott Cell, and the Concentration Calculation Algorithm.
This website provides an easy-to-understand introduction of the principles and features of this new core analytical technology that will become the standard for the next generation gas analysis.
The IRLAM logo was designed to resemble the three lights and multiple reflections of laser light in a Herriott Cell. The three lights represent the three proprietary technologies that support the high performance: QCL, Herriott Cell and Concentration Calculation Algorithm, and the multiple reflections illustrate the multiple features of IRLAM: High Sensitivity, Low Interference, Compact Size and High Reliability.
This logo will be attached as an emblem to various HORIBA gas analyzers equipped with IRLAM technology, proving that they are gas analysis instruments that realize the unparalleled performance.
