Campbell Scientific TGA100A System Specification

The Campbell Scientific TGA100A Trace Gas Analyzer is a sophisticated system designed for precise measurement of trace gases in various research and environmental monitoring applications. This highly sensitive instrument utilizes tunable diode laser absorption spectroscopy (TDLAS) to detect specific gas species with exceptional accuracy and speed. The TGA100A system is renowned for its ability to measure gases such as methane (CH₄), nitrous oxide (N₂O), carbon dioxide (CO₂), and water vapor (H₂O) in real time, making it ideal for studies involving gas fluxes and concentrations in atmospheric, ecological, and agricultural environments.

The core of the TGA100A is its tunable diode laser, which offers high selectivity and sensitivity by targeting absorption lines unique to each gas species. This capability allows for minimal interference from other gases and ensures precise measurements even in complex gas mixtures. The system's modular design includes a sample cell, laser control unit, data acquisition system, and a vacuum pump, all optimized for seamless operation and integration.

With a rapid response time, the TGA100A can capture dynamic changes in gas concentrations, providing valuable insights into temporal gas flux variations. The system is equipped with advanced data processing software, facilitating real-time data analysis and visualization. Its robust construction ensures reliable performance in field conditions while maintaining laboratory-grade precision. The TGA100A's versatility and accuracy make it a critical tool for researchers and scientists seeking to understand and quantify trace gas dynamics in various environments.
