Product details
Product Overview
The EXPEC 271 Su Code Can Automatic Sampling Instrument is suitable for on-site sampling of VOCs in the ambient atmosphere. It adopts negative pressure sampling technology, and the air sample will not pass through the sampling pump. The sample flow path is treated with inertization to prevent pollution caused by the flow path itself, reduce sample residue and adsorption, and ensure the stability of the collected samples.
Product Features
Multiple sampling modes
Flow path design, when the environmental concentration exceeds the threshold, instantaneous sample retention is completed within 60 seconds; Constant current sampling is also possible, with a flow rate of 0.2~500mL/min, meeting the sampling time requirements of HJ 759.
Dual channel design
Dual channels can be opened simultaneously to achieve parallel sampling, or when one channel samples, the other channel can be used for tank replacement operation, achieving blind spot free sampling.
Leak-proof design
When the instrument is in standby mode, the rotary valve is in a sealed state to prevent slight leakage in the flow path, which may cause changes in the vacuum degree of the Suma tank and affect data quality.
Low adsorption design
All flow paths are treated with inerting and heat tracing, with low adsorption, low residue, and low cross contamination.
Extended features
Standard configuration includes 8 sampling bits, but can also be expanded to 16 sampling bits.
Application field
Environmental monitoring, emergency monitoring, occupational health, public health, scientific research
