FTIR Extraction Monitoring System

Product description and operating principle

The IMACC FTIR extraction monitoring system injects sample gas into its internal attachments through an extraction pipeline (and pump). The system can collect more customizable and highly rated devices in the industry:

IMACC's FTIR adopts a unique design, adding monitoring accessories on the basis of the original standard version to achieve multifunctionality, meeting various monitoring needs while saving costs.

The standard basic units include:

After passing through the sample, a continuous spectrum is obtained and a continuous reading of gas concentration is provided.

You can use it with confidence:

IMACC's technology should be applied globally in the industrial, petrochemical, and chemical industries, and has been adopted by the US EPA and other air quality monitoring agencies for atmospheric emissions.

Diversified applications:

Extractive attachments can monitor air quality at multiple locations

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.

Product selection provided by FTIR extraction system:

The monitoring system measures gases with high temperature/humidity. Therefore, all accessory units come with an option for temperature heating control, allowing them to operate normally in environments up to 200 ° C. This is necessary for monitoring saturated airflow and high-temperature airflow. According to different detection ranges, various specifications of air chambers are available for selection.

5 cm, 10 cm, or 25 cm fixed optical path length for percentage concentration levels

1 m-10 m adjustable optical path length chamber for higher ppb concentration levels

4 m-32 m adjustable optical path length chamber for medium ppb concentration levels

20 m-150 m adjustable optical path length gas chamber for individual ppb concentration levels

Due to the fact that both the chamber and its transmission lines are in a heated state, all measurements are conducted at a certain temperature and humidity.

The correct accessory equipment is determined by the sample taken. Units with relatively short fixed optical path lengths are used for detecting samples with a detection limit of 0.05%, units with a length of 1-10 meters are used for monitoring at ppm concentration levels (0.1 ppm), structural units with a length of 4 to 32 meters can provide detection at high ppm or medium ppb levels (30-50 ppb), and the largest structural units with a length of 25 to 150 meters are used for detection at low concentration ppb levels (1-2 ppb). All attachments can be used interchangeably in each basic unit of FTIR.

Detection limit:

The detection limit is affected by atmospheric samples and their components. The detection limit may vary slightly with time and sample flow. For each system, IMACC provides detection limits for all compounds that are important to the site. IMACC's chamber based system can achieve detection limits close to the noise limit, especially when using sample processing.

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.
