PTM300 Portable Gas Chromatograph for On Site VOC Analysis with
High Accuracy
OVERVIEW
The PTM300 portable gas chromatograph uses a high-sensitivity
photoionization detector to detect extremely low concentrations of
volatile organic compounds (VOCs) and other toxic gases. It is
designed with a completely independent dual chromatographic system.
The analyzer adopts an ergonomic backpack design, suitable for
outdoor use. It has a built-in rechargeable lithium battery that
supports continuous operation for more than 6 hours. It has a
built-in small carrier gas bottle that supports fast filling; it
also supports the machine to purify air as a gas chromatograph
carrier gas.
FEATURES & BENEFITS
1. Detection of extremely trace (ppb) volatile organic compounds
(VOC);
2. Rapid detection of volatile organic gases in air, water and
soil;
3. Highly sensitive detection of VOCs gas components such as
benzene, toluene, xylene, styrene, etc.;
4. Equipped with a handheld data terminal (PDA), the wireless
communication distance is greater than 30 meters;
5. The carrier gas uses high-purity nitrogen, helium or zero-grade
air, and the built-in gas cylinder supports rapid filling;
6. Supports the use of purified air as carrier gas, and can work
continuously without external carrier gas;
7. Equipped with a sampling pump and an automatic injection valve,
the analysis can be completed with one click in the software
workstation;
8. (Optional) Completely independent dual chromatography system,
which can work simultaneously or separately;
9. The analytical column uses a 30-meter stainless steel capillary
column, and the pre-column and multi-position valve realize the
separation of complex components;
10. Built-in chromatographic library of more than 40 gas analyses,
supports new analysis methods, and expands the spectrum library.
