加拿大优胜公司成立于1980年，是专业的气体检测仪器研发生产公司，是可调式二极管激光器吸收光谱（TDLAS）气体检测技术的倡导者和领导者，这种地位保持至今。

1994年Unisearch 推出基于TDLAS技术的LasIR气体检测系统，应用领域包括空气质量监测、排放监测（CEM）、过程控制检测。至今，LasIR气体检测系统已被广泛安装到世界各地。

在中国，LasIR气体检测系统也有数十套被安装使用，应用领域包括科研所、大学、电解铝厂、单晶硅厂、化工厂、火电厂、核电站等。让更多的应用领域使用上高质量的气体分析系统，让用户由衷的满意，是我们不懈的追求！

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.
