PTM300 Portable Gas Chromatograph for On-Site VOC Analysis with 6-Hour Battery and 5 kg Weight

The PTM300 portable gas chromatograph utilizes a high-sensitivity photoionization detector for detecting extremely low concentrations of volatile organic compounds (VOCs) and other toxic gases. Featuring a completely independent dual chromatographic system and ergonomic backpack design, this analyzer is optimized for outdoor field applications.

Equipped with a built-in rechargeable lithium battery supporting over 6 hours of continuous operation and an integrated carrier gas system that supports rapid filling or purified air operation, the PTM300 delivers reliable on-site analysis capabilities.

• Detection of extremely trace (ppb) volatile organic compounds (VOCs)
• Rapid detection of VOCs in air, water, and soil samples
• Highly sensitive detection of benzene, toluene, xylene, styrene, and other VOC components
• Wireless handheld data terminal (PDA) with communication range exceeding 30 meters
• Carrier gas compatibility with high-purity nitrogen, helium, or zero-grade air
• Built-in gas cylinder supports rapid filling and purified air operation
• Integrated sampling pump and automatic injection valve for one-click analysis
• Optional independent dual chromatography system for simultaneous or separate operation
• 30-meter stainless steel capillary column with pre-column and multi-position valve for complex component separation
• Built-in chromatographic library with over 40 gas analyses and expandable spectrum library

This portable gas chromatograph is ideal for industrial hygiene, indoor air quality (IAQ) assessment, vehicle air VOC and aldehyde/ketone detection, benzene leakage monitoring, site characterization, and sulfide/odor gas detection.

Compatible test samples include: vinyl chloride, dichloroethylene isomers, trichloroethylene, tetrachloroethylene, ethylene chloride, naphthalene, ethylene oxides, alkanes up to octane, chloromethanes, light chlorobenzenes, hydrogen sulfide, mercaptans, organic amines, organic sulfur compounds, ketones, arsine, phosphine, aldehydes, ethylene glycol esters, Freon compounds, isocyanates, acrylates, and light alcohols.
