Dual function gas analyzer

Product description and operating principle

IMACC's DFGA emits an infrared beam to measure the infrared absorption of gas molecules, while using visible laser to provide molecular Raman morphology with or without FTIR signals. This technology can simultaneously read nearly 50 compounds in real-time, measuring as low as ppb levels, and does not require recalibration time.

More customizable and highly rated equipment in the industry:

The FGA design of IMACC is unique, combining standard FTIR basic units with suction chamber system accessories and necessary Raman components.

Significant features:

Simple fully automated operation

Real time monitoring of over 50 compounds

Complete alarm function for compounds

Fully remote access to pre programmed software with graphical interface and display system

More sturdy and durable:

IMACC's dual function gas analyzer system can maintain optimal alignment even in extremely harsh environments, resisting the effects of sudden temperature changes or surrounding instrument vibrations.

Rest assured to use:

Nowadays, IMACC FTIR technology is mainly used in important industries, petrochemicals, and chemical plants worldwide, and is adopted by the US Environmental Protection Agency (EPA) and other atmospheric emission air quality monitoring agencies. The additional Raman performance of this product provides innovative spectral performance for industrial monitoring applications.

Diversified applications:

Smoke gas monitoring: Continuous emission monitoring of smoke ducts, exhaust pipes, or environmental protection treatment devices.

Process control monitoring: Real time continuous monitoring of industrial processes or process gases, and feedback of the results to the alarm system.

Buildings, warehouses, chemical factories, landfills, and mines: Monitor employee exposure levels or gas accumulation levels in enclosed environments in areas with pollutant emissions.

Product selection:

The dual function gas analyzer provides a closed chamber accessory for monitoring gaseous compounds that come from the atmospheric sampling environment and are transported to the chamber for analysis. The concentration range of FTIR is mainly determined by the gas chamber used, and the energy of the laser is the main source of all measured Raman signals. The chamber and its transmission lines are both in a heated state, so all measurements are taken at a certain temperature and humidity.

Detection limit:

The IMACC dual function gas analyzer system can provide customized analysis routines according to different monitoring needs. The detection limit depends on the target compound, optical path length, and response time. Increasing the optical path length and sampling time, or increasing the laser intensity, can achieve lower detection limits.

Typical compound detection limit*

ND-FIR cannot detect

software package

Each device is equipped with a complete and user-friendly control and imaging software package under the Windows operating system. The image display includes a series of line graphs showing the implementation relationship between gas concentration and time, bar graphs comparing gas concentration and alarm levels, and concentration relationship graphs between different compounds. Users can also generate custom spreadsheet reports through report generation software.
