加拿大優勝Unisearch Associates  
加拿大優勝公司成立于1980年，是專業的氣體檢測儀器研發生產公司，是可調式二極管激光器吸收光譜（TDLAS）氣體檢測技術的倡導者和領導者，這種地位保持至今。

1994年Unisearch 推出基于TDLAS技術的LasIR氣體檢測系統，應用領域包括空氣質量監測、排放監測（CEM）、過程控制檢測。至今，LasIR氣體檢測系統已被廣泛安裝到世界各地。

在中國，LasIR氣體檢測系統也有數十套被安裝使用，應用領域包括科研所、大學、電解鋁廠、單晶硅廠、化工廠、火電廠、核電站等。讓更多的應用領域使用上高質量的氣體分析系統，讓用戶由衷的滿意，是我們不懈的追求！

UNISEARCH is a team of people committed to mutual respect, professional conduct and a passion for excellence. Our worldwide network of sales representatives is complemented by a full staff of installation and service experts.

The company also maintains a strong R&D focus to retain its status as an industry leader, both for its current products and for its development of new product lines.

Founded in 1980, UNISEARCH pioneered and quickly became a world leader in the use of Tunable Diode Laser Absorption Spectroscopy (TDLAS) for air measurements—a position it still enjoys today.

In 1994, the company introduced its LasIR system of instruments, which extends our TDLAS technology to the use of telecommunication Tunable Diode Lasers. Applications for LasIR instruments include air quality measurements, fence-line monitoring, CEM and process control. Systems have been installed around the world.

In the early ’90s, the company developed an improved Differential Optical Absorption Spectrometer (DOAS) system, and in 1995, licensed the technology to Thermo Environmental Instruments.

Also in 1995, UNISEARCH acquired advanced Fourier Transform Infrared (FTIR) technology and opened its Austin, Texas, plant to manufacture FTIR instruments. Since then, we have developed and installed a number of FTIR systems, used mainly for fence-line monitoring and for extractive CEM and process control.

Prior to the acquisition of FTIR, UNISEARCH developed its patented LUMINOx? line of instruments. Based on a novel surface-chemiluminescence technique, these lightweight, battery-operated instruments are highly sensitive and detect NO2, NO, NOy, O3 and PAN.
