AD310L Standard Gas Generator
Product Introduction
A stationary laboratory system for precise dynamic generation of standard gases. Microfluidic control delivers small liquid quantities with stable metering and dilution, with optional online mixing of gaseous samples. The platform supplies traceable calibration mixtures for VOC analyzers and gas sensors, method development, odor research and environmental calibration.

The standard platform provides first-stage dynamic generation.
Add secondary dilution for low-concentration output,
or independent gas channels for controlled mixed liquid/gas sources.
Microfluidic Dosing and Flash Evaporation
Conventional syringe pumps can produce mechanical pulsation and lose accuracy at low flow. Peristaltic pumps create pulses as rollers compress tubing, with tubing wear and frequent maintenance.
Pressure-driven, pump-free injection
Closed-loop electronic pressure control, precision restrictions and a laminar-flow structure provide stable, pulse-free microliter delivery.
Thermal flash evaporation and capillary pressure splitting rapidly vaporize liquid and produce a stable ppb-level gas stream.
