H6 Intelligent Headspace
Automated Purge-and-Trap Headspace for GC/GC-MS | NWSPEC GC Accessory Series
The H6 is a sample pretreatment accessory that automates purge-and-trap headspace analysis for GC and GC-MS systems. It uses high-precision syringe sampling with helium/nitrogen purge gas, trapping volatile compounds from liquid or solid matrices for sensitive chromatographic detection.
GC Applications
- Drinking water and wastewater organic pollutant analysis
- Food and beverage odor component profiling
- Pharmaceutical residual solvent testing (USP/EP)
- Environmental soil and sediment volatiles
- Polymer and resin outgassing characterization
- Cosmetics and fragrance volatile analysis
- Forensic toxicology sample screening
- Industrial chemical purity verification
Pretreatment Features
- 54 sample positions: High-capacity batch processing with 10 heating positions
- Sample vibration: Standard oven vibration with stepless speed regulation
- Overlap injection: Consistent equilibrium time for every sample
- XYZ robotic arm: Stable and reliable vial handling
- GC-integrated control: All parameters edited via chromatograph screen
- Method storage: 20 headspace method files, directly retrievable
- Electronic flow control: High-precision gas path regulation module
- Internal standard addition: 4-position 40ml automatic addition module
- Surrogate spiking: Automatic surrogate addition for QA/QC
- Vial status monitoring: Real-time in-place detection
- Leak detection: Pre-test check for each sample position
- Bubble detector: Standard sensor with automatic defoaming
- Process traceability: Actual parameters recorded per sample
- UniLite integration: Method seamlessly embedded in GC workflow

Compact GC System
Entry GC System
Via standard I/O
System Integration: The H6 operates as a fully integrated pretreatment module within the Mx series GC/GC-MS method structure. All headspace parameters—including oven temperature, equilibration time, purge flow, and trap desorption—are edited in the same method file as column and detector settings. The XYZ robotic arm, bubble detector, and leak check work autonomously while the GC runs previous samples, maximizing throughput.
