Model 529 online VOCs analyzer

Date: 2018-01-22

Based on the principle of GC-FID, the Model 529 is heated to a high temperature by the sampling system and the analysis system. THC and CH4 can be measured separately by column separation and backflushing techniques to calculate the NMHC of non-methane hydrocarbons. Analyzer built-in sampling diaphragm pump can be automatically injected. The instrument can adjust the chromatographic system and set up chromatographic software according to the need, measure the content of the specified kind of gas. Up to 8 specified gas components can be measured separately, except for the total methane. According to the need to configure the benzene series separation column, measuring benzene, toluene, xylene and other content.

 

Working Principle:

529 analyzer using GC-FID principle, hydrogen flame ion detector. After the sample gas enters the analyzer via the sample pump, the column is filled with PQS or a suitable material through a 10-way rotary valve and the methane fraction is separated. The separated CH4 is sent to the FID detector, whose response is processed and stored by the built-in microprocessor. In the second stage of the 10-way rotary valve, the column enters the backflush process while the sample from the total hydrocarbon sample column is introduced into the FID detector to measure the total amount of hydrocarbons (THC). The total non-methane hydrocarbons in the sample are calculated by subtracting the methane component from the total hydrocarbon signal.
