TGA200A迹线气体分析仪使用可调谐二极管激光吸收光谱(TDLA)测量空气样品中的痕量气体浓度。该技术提供了高灵敏度,速度和选择性。其简单的设计允许通过选择合适的激光源来测量许多气体之一。TGA200A功能1.5 M使用a的单通光学测量系统热电冷激光。
TGA200A容纳在坚固的环境外壳中,设计用于苛刻的气候,从高纬度的北方森林,永久冻土和苔原到农业密集的中纬度地区和赤道雨林。常见应用包括慢性梯度或高速涡流的氧化氮助熔剂或甲烷形式的碳通量,或所有全球生态系统中二氧化碳的同位素。
Campbell Scientific has been manufacturing TGAs since 1993, and the TGA200A is the result of over 20 years of research and development. Even though previous generations of the TGA (TGA100, TGA100A, and TGA200) have the same core technology, the TGA200A builds upon this succession with further improvements.

使用Campbell Scientific Logger从TGA200A收集数据。TGA200A与支持SDM通信的数据记录器兼容。在许多情况下,使用TGA200A订购包含数据记录器的采样系统。请联系Campbell Scientific获取有关采样系统的更多详细信息和与用户提供的组件(例如叶室)的兼容性。
TGA200A固件用于支持已经升级的TGA200A或先前TGA模型以使用热电冷却(TEC)激光器。
The TGA firmware includes the OS that must be uploaded to the analyzer's CPU board before operating a TEC laser.
警告:TGA200A固件的下载只能与运行TEC激光器的TGA型号一起使用!
The TGA TEC Support Software is used to support the TGA200A or prior TGA models that have been upgraded to use a thermoelectrically cooled (TEC) laser.
TGA TEC is a user-interface software package that allows users to connect to the analyzer, set settings, and monitor real-time analyzer performance.
兼容性:
TGA TEC 1.1与Windows 7操作系统或更新兼容。
警告:仅适用于运行TEC激光器的TGA型号的TGA TEC V1.1的下载!
