Nutech Online Pre Concentrator

The main uses of Nutech online pre concentrator are:

The 6600 online pre concentration analyzer developed by Nutech, combined with quadrupole mass spectrometry, enters the detector for analysis through front-end low-temperature composite iterative enrichment and concentration pretreatment, achieving online continuous monitoring of more than 100 VOCs. Widely used for air quality monitoring (environmental monitoring stations, meteorological stations, etc.), air quality monitoring around pollution source factories or chemical industrial parks.

Performance characteristics of Nutech online pre concentrator:

（1） The low-temperature composite iterative enrichment pre concentration technology effectively enriches and concentrates the target compound to be tested, and quickly performs thermal analysis, greatly improving the detection limit and meeting the detection needs of low or ultra-low concentration air VOC components.

(2) Deep cold and low-temperature water treatment technology efficiently removes water from the sample air CO₂Waiting for interference greatly improves peak shape, prolongs the lifespan of chromatographic columns and ion sources.

(3) The integrated design of water-cooled trap and enriched cold trap, shorter sample pipeline and constant temperature are beneficial for improving component recovery.

(4) It has independent internal and external standard interfaces, can automatically collect internal and external standard gases, has reference analysis methods (editable), supports two quality control modes: online standard addition quality control and Suma tank sampling offline analysis quality control, and meets the requirements of national standard online environmental air monitoring quality control.
