PTM300 Portable Gas Chromatograph for On-Site Gas Analysis
The PTM300 Portable Gas Chromatograph is designed for professionals in environmental monitoring, food safety, and industrial quality control, providing rapid and accurate analysis of gases and volatile compounds on-site.
Its compact and lightweight design ensures that users can easily transport it to various locations, enabling real-time testing and immediate decision-making in diverse settings. Ideal for fieldwork and laboratory applications alike, the PTM300 empowers users with reliable data to enhance productivity and compliance across various industries.
Overview
The PTM300 portable gas chromatograph features a high-sensitivity PID detector and utilizes GC-PID technology to achieve precise VOC detection. It is available in two configurations—pre-concentration and direct-injection—to meet the needs of various applications. Weighing less than 5 kg and offering over 6 hours of battery life, the instrument uses self-generated purified air as the carrier gas, eliminating the need for an external gas source. Equipped with a 5-inch touchscreen and a built-in sampling pump, it performs the entire analysis with a single touch and provides real-time concentration data, making it an ideal tool for ambient air monitoring and rapid on-site testing during emergency incidents.
Features
▪ High Efficiency and Precision for Emergency Monitoring Equipped with a high-sensitivity PID detector offering ppb-level detection limits; analyzes BTEX compounds in under 10 minutes per run, enabling rapid response for on-site emergency monitoring.
▪ One-Touch Operation, Fully Automated Features a built-in sampling pump and automatic injection valve; a single tap on "Start Analysis" automates the entire process—sampling, separation, and detection.
▪ Lightweight, Portable, and Long-Lasting The main unit (including battery) weighs ≤5 kg and is portable with one hand; the high-capacity lithium battery supports ≥6 hours of continuous operation, meeting the demands of a full day of field tasks.
▪ Intuitive Touchscreen Control
A 5-inch color touchscreen displays test progress, instrument status, component concentrations, and trend charts in real-time; supports on-site report printing via Bluetooth.
▪ Smart Software with Guided Operation
Features a Chinese-language web-based workstation with a guided workflow; integrates historical data queries, chromatogram viewing, and report generation—no specialized training required.
▪ Closed-Loop Enforcement and Evidence Preservation
Integrates GPS positioning, wireless data transmission, and Bluetooth printing; generates location-tagged test reports with one touch, ensuring complete preservation of enforcement evidence.
▪ Sample Pre-treatment
Compatible with portable headspace or purge-and-trap injection systems, enabling rapid on-site pre-treatment and analysis of BTEX compounds in water and soil samples.
