Lausanne, Switzerland, February 1st, 2008
Lausanne/Switzerland based ^®IR Microsystems, a leader in compact, tunable laser diode based gas sensors for monitoring, safety and process control, presents an innovative sub-ppm ammonia gas detector. The drift-free detector shows an excellent RMS noise of only 0.15 ppm, with perfect linearity up to 1000 ppm. The sensors are targeted toward applications in industrial safety, refrigeration, emission control, life-stock farming and agriculture.

“The ammonia sensor performance combined with its long lifetime is unmatched in this class of instruments and especially out-plays traditional electrochemical cell sensors” says IR Microsystems’ CTO, Dr. Bert Willing.

The “microLGD” gas sensors are offered as stand-alone systems or OEM sub-mounts for the continuous monitoring of NH₃ and other gases like O₂, CO₂, CH₄, H₂O, etc. Compared to current gas sensor technologies, IR Microsystems’ “Next Generation Gas Detection” products feature exceptional advantages like extremely high selectivity, calibration-free operation, low-cost-of-ownership, and functional safety.

The patented measurement principle is based on Tunable Diode Laser Spectrometry (TDLS) and results in unique products without a reference channel, allowing for simpler, lower-cost systems. The sensor comprises a microprocessor-driven read-out module with digital and analog data outputs for industry-standard connectivity (I²C-bus, RS485, RS232, or 4-20 mA). The unit is built ready-to-use for rapid OEM integration into stand-alone units, detector networks or explosion-proof housings.

With its extremely high selectivity, functional safety, calibration-free operation, very good long-term stability, long lifetime, and scalability of cost, this breakthrough technology is set to change the gas detection landscape.

COMPAMED 2007, Düsseldorf, Germany - November 14th-16th, 2007

Lausanne/Switzerland based ^®IR Microsystems, subsidiary of Leister Process Technologies, presents a range of compact gas sensors based on telecom-type tunable laser diodes. The innovative sensors are targeted toward applications in medical technology, industrial safety, selected process control, and others. Our products offer exceptional advantages compared to current gas sensor technologies, notably in terms of fast response time, functional safety, selectivity and low cost-of-ownership. The microLGD gas sensors are offered to OEM customers as stand-alone systems or sub-mounts for the continuous monitoring of gases like, O₂, CO₂, H₂O, NH₃, and others.

IR Microsystems’ patented measurement principle is based on Tunable Diode Laser Spectrometry (TDLS) and uses a novel, reference channel-free measurement concept, allowing for simpler, compact systems. The sensor comprises a laser diode measurement head and a microprocessor-driven read-out module with digital and analog data outputs for industry-standard connectivity (4-20 mA, RS485, RS232).

Applications in medical technology using fast mainstream monitoring of O₂, CO₂ and water may include:

• Pulmonary diagnostics
• Metabolic diagnostics, total parenteral nutrition (TPN) optimization for cost-reduction in critical care
• Ergo-Spirometry
• others
