Gas autosampler HS-20 NX

watervolatile organic compoundheadspace

Overview
The HS-20 NX series is a headspace sampler designed for volatile component analysis by headspace GC/MS. The NX upgrade improves baseline performance and usability, making the system suitable for both research and quality control laboratories. The series offers an optional Trap model for enhanced sensitivity and flexible carrier-gas options.

Product type
Headspace Sampler

Key features

• Optional Trap model (concentrates samples for 10–100× higher sensitivity)
• Loop mode available for routine analyses
• Electronic AFC (Advanced Flow Controller) for precise carrier-gas control
• Supports nitrogen (N2) and hydrogen (H2) carrier gases
• Low carryover and short inert flow path for improved reproducibility
• Direct column connection to the sampler; GC injector remains available for liquid injections
