Product principle

The system adopts negative pressure sampling and high-temperature tracing throughout the process to ensure that the sample gas does not condense. After passing through the high-temperature pretreatment unit, the sample gas enters the analyzer. Sulfides are separated by blowing the carrier gas into the analysis column and then sequentially enter the flame photometric detector (FPD) for detection. The external standard method is used to accurately achieve qualitative analysis of sulfides, and accurate quantification of sulfides is achieved based on peak area.

Product Features

The analyzer adopts positive pressure control gas bath heating, which makes the temperature inside the column box more uniform and can quickly eliminate possible hazardous substances; Adopting dual safety protection with travel switch and pressure monitoring;
The carrier gas, combustion gas, and combustion assisting gas are all controlled by electronic flow control. We have independently developed high-quality EPC and PID algorithm regulation, which has strong anti-interference ability and high control accuracy. The control accuracy can reach ± 0.01ml/min;
Imported ten way valve: small dead volume, long service life;
The pipelines and components have undergone sulfur passivation treatment to reduce adsorption;
Industrial grade online analytical instrument design, fully automatic sampling design, capable of achieving uninterrupted online monitoring function;
The intelligent chromatographic processing system has functions such as intelligent recognition, automatic recording, automatic diagnosis, automatic alarm, data acquisition, processing, display, storage, query, and output of spectra;
◆ Support customization, a set of analyzer can be matched with multiple detectors, customized pre-processing devices and process control can meet the testing needs of different working conditions;
The instrument has power on self-test, automatic ignition, flame status monitoring, shutdown protection and alarm to ensure system safety and stability;
Explosion proof (Ex d e mb px IIC T4 Gb)/non explosion proof optional, suitable for different safety requirements;
