S10 TGA-GC/MS Multi-Loop Sampler
S10 TGA-GC/MS Auto-Sampler
Automated Sample Introduction from Thermogravimetry to GC-MS | NWSPEC GC Accessory Series
The S10 is an automated sample introduction accessory that captures time-resolved gas evolved from thermogravimetric analyzers (TGA) and feeds stored samples sequentially into GC-MS for analysis. It solves the fundamental timing mismatch between rapid TGA weight-loss events and slower GC-MS analysis cycles.
Problem Solved by S10
In traditional TGA-GC-MS setups, users can only inject one sample per TGA run. By the time GC-MS analysis completes, the TGA thermal event is already over—preventing multiple sampling. The S10 auto-sampler captures up to 16 time-resolved samples automatically and introduces them sequentially into the GC-MS.
GC-MS Applications
- Rubber and polymer thermal degradation analysis
- CO2 emission profiling during material heating
- Volatile organic compound evolution tracking
- Pharmaceutical thermal stability studies
- Coal and biomass pyrolysis gas analysis
- FTIR medium gas bypass analysis supported
Auto-Sampler Features

- Automatic trapping: Sample gas captured in loops per programmed schedule
- Sequential injection: Stored samples introduced into GC-MS one by one
- Software-configurable timing: Sampling intervals set per TGA heating program
- Integrated gas sampling valve: Built-in GSV—no GC-end configuration needed
- Plug-and-play inlet: 1/32" inert tube inserts into standard GC S/SL port
- Zero GC modification: No changes required to injection port
- Universal mounting bracket: Compatible with mainstream GC-MS systems
- Heated valve box: All valves and loops heated up to 300°C (max 330°C)
- Inert treatment: All sample tubes treated to prevent adsorption
- Concentration curves: Component trend export via chromatograph software
- Bypass to FTIR: Parallel connection to infrared analyzer supported

With MS Module
System Integration: The S10 auto-sampler acts as a time-resolved sampling bridge between TGA and GC-MS. Users program sampling intervals matching their TGA heating ramp. The S10 automatically stores evolved gases and feeds them sequentially to the GC-MS—enabling complete thermal profile analysis that was previously impossible with single-injection setups.
