The Nutech 8910CF high-performance VOC preconcentration system is designed for ultra-trace analysis of volatile organic compounds in air and gas samples without the use of liquid nitrogen.
The preconcentrator utilizes an advanced three-stage trapping technology featuring electronic cooling and integrated moisture and CO₂ management. This technological solution ensures ppt-level sensitivity, with detection limits down to 0,01 ppbv and concentration ratios exceeding 1000:1.
Designed for seamless integration with GC and GC/MS platforms, it natively supports major international regulatory methods without requiring hardware modifications.
The fully inert sample path, accurate volume control via MFC, and high-speed thermal desorption ensure maximum data repeatability, even for polar and reactive compounds.
Key Features
- Cryogen-Free Technology: Electronic cooling down to -30 °C without liquid nitrogen.
