Gas analysis through TDLAS
NEOLund AB develops high-resolution tunable diode laser absorption spectroscopy (TDLAS) technology platforms for gas analysis instruments.
The technology employs a tunable narrow-band laser to measure the unique absorption imprints of gas molecules. An advanced data analysis is then carried out to determine the concentration, pressure and/or temperature of the analyzed gases.
The technology is fast, reliable and accurate. In addition the TDLAS platform can also be multiplexed, providing measurements of multiple gas species simultaneously and can be employed for gases in the atmosphere as well as free gases encapsulated within solid or liquid media.
The LIDAR systems developed by NEOLund AB are unique in the sense that they do not operate in the time domain with short pulses. Instead, the range information is provided through geometric relationships. This allows for extremely compact, inexpensive and very fast systems (kHz) as compared to traditional pulsed high-power systems.
The unique design of the LIDAR systems allow them to be customized and tailored for the application, and the systems can be designed to measure in the m-range as well as in the km-range with sub-cm resolutions.
Through the LIDAR systems, NEOLund can provide range-resolved information with high time-resolution to measure particles, aerosols, gases or other inhomogeneities in the atmosphere and in other media, such as water or oils.
