Portable handheld total hydrocarbon (VOCs) analyzer FID principle

The FID principle of M2 portable total hydrocarbon (VOCs) analyzer

Product Introduction

M2 is a handheld hydrogen flame ionization detection (FID) analyzer with detection accuracy up to ppb level, displaying and recording any concentration value within the range in real time. At the same time, it can integrate any sensor such as PID, oxygen, carbon monoxide, carbon dioxide, and hydrogen sulfide. By using low-pressure solid-state hydrogen storage alloy technology in conjunction with a portable hydrogen generator, the safety hazards and inconvenience of using high-pressure hydrogen in traditional FID have been overcome, and the purchase and management costs of using hydrogen as combustion gas have been eliminated. And it improves the flexibility and immediacy of the detection work, and the built-in automatic calibration function reduces the use of standard gas operation conditions in calibration work.
