Description
EXPEC1680 Portable Fourier infrared analyzer
EXPEC 1680 Portable Fourier infrared analyzer is developed based on the fact that different gases have different absorption characteristics within the infrared spectral range. By adopting the principle of the Fourier infrared spectroscopy and multiple resolution correction methods, it can be used to measure gases qualitatively and quantitatively. It meets the requirements of standard regulations such as *** Ambient Air - Emergency Monitoring Method for Inorganic Hazardous Gas - Portable Fourier Infrared Spectrometer Method (HJ 920-2017)
*** Ambient Air - Determination of Volatile Organic Compounds - Portable Fourier Infrared Spectrometer Method (HJ 919-2017).
Factor monitoring: It can monitor more than 50 types of organic and inorganic gases, including NH3, HF, HCl, formaldehyde, propane, ethylene, propylene, acetylene, benzene, toluene, ethylbenzene and styrene.
The measurement does not require any pretreatment, wet chemical analysis, or tedious calibration, and can be directly operated on the instrument touch screen or the external laptop. The system can monitored on site automatically for a long time without being on duty.Features:* High-resolution, wide spectral range
Optical path can reach 13m, with low detection limit and wide spectral range, suitable for ultra-low emission monitoring.
Employ Least Square Method (LSM) and PLS algorithm, automatically select appropriate spectral range, effectively
eliminate H2O interference. * No need for preheating, fast sampling and measurement
Equipped with two kinds of pretreatment system to match with analyzer: condensate water removal or
High temperature heating throughout the whole process. * High reliability
Dividing into normal temperature type and high temperature type, meeting requirements of various working conditions. * High integration
Equipped with purge system, which can automatically purge according to the workflow, ensure measurement accuracy and equipment safety. Built-in sampling system, realize automatic temperature control. * Easy operation & communication
Equipped with a visual touch system, status is clear at a glance. Integrated with wifi module for
remote communication.Specification:| Measurement technology: | FTIR |
