Description

Features

The PRO-TECH online gas mass spectrometer is independently developed and optimized based on conventional mass spectrometry systems.

Key components such as gas pipelines, intelligent control systems, and sampling modules have been upgraded to support multiple application scenarios and multi-channel sampling.

This provides significant improvements in overall performance and operational efficiency.

High Sensitivity

Dual detector configuration:

  • Faraday Cup

  • Electron Multiplier

This enables detection across a wide concentration range:

Major concentration (100%) → trace levels (ppb).

Typical Use Cases

Examples of instrument coupling include:

  • TGA-MS (Thermogravimetric analysis with mass spectrometry)

  • Chemisorption-MS

  • FTIR-MS

  • Catalytic reactor-MS

These configurations allow researchers to analyze reaction products, gas evolution, and reaction mechanisms in real time.
