EGABOX: ATG-GC/MS Coupling Interface for Emis Gas Analysis (EGA)
Decouple the ATG measurement time from the GC-MS analysis time. Capture the complete kinetics of your rapid reactions at high temperature.
The EGA Challenge: Away from the GC-MS Time Constraint
The analysis of the gases emitted (EGA) during an ATG test or at the reactor outlet often encounters the rapid response to GC-MS analysis time. The interface EGABOX interface eliminates this analytical bottleneck by automatically trapping key gas fractions at 200 °C. You can then analyze each sample sequentially, without losing track of your reaction kinetics.
Bridge the Gap Between TGA and GC-MS Analysis Time
In materials and polymer characterization, Gas Chromatography coupled with Mass Spectrometry (GC-MS) is the absolute reference for the qualitative and quantitative analysis of the gases emitted (EGA) during a testThermal Gravimetric Analysis (TGA) runs..
In materials and polymer research, TGA (Thermogravimetric Analysis) is the standard for monitoring mass loss. Coupling these degradation steps with a detailed gas analysis (EGA) provides vital structural information. However, a major bottleneck exists:
However, a major timing conflict arises:
-
A TGA cycle or rapid reaction typically lasts 10 to 30 minutes.
-
A comprehensive chromatographic separation via GC or GC-MS requires 20 to 60 minutes.
How to capture the entire degradation levels without missing any gaseous fraction?
The interface EGABOX solves this temporal problem: it samples and stores the gases emitted at high temperature (up to 200°C) in dedicated loops, at programmable temporalities synchronized with your mass losses. Each fraction is then injected sequentially 100% automatedly into your GC or GC-MS.
Why choose EGABOX for your ATG couplings or kinetic processes?
Engineered for researchers and R&D teams, the EGABOX interface Chemlys turns your GC-MS system into a powerful kinetic tracking tool. It interfaces directly with your reactors or thermal analyses to preserve the exact picture of the gases emitted during rapid reaction phases.
1. Repeatable Gas Sampling & Reliable Quantification
Every EGABOX undergoes rigorous factory validation. We guarantee Exceptional interloop repeatability (RSD < 0.5% on GC peak area). Each unit is delivered with its own qualification certificate.
2. Ergonomics & Flexibility of Use
-
Unconstrained Control: Automation and embedded web software without license. Access configuration from any browser without third-party software installation.
-
Disconnect Your GC in Under 5 Minutes: The heated transfer line (without cold spot) disconnects very quickly. Your GC-MS remains available for further routine analysis.
-
Simplified maintenance: Direct valve access right under the front cover.
3. Sample Integrity & Safety
-
Inert Passivation (SilcoNert® 2000 Option): Complete treatment of valves and transfer lines to prevent adsorption of reactive, sulfur-containing, or trace compounds.
-
Gas safety: Option of automatic neutral gas scanning in case of leak detection (ideal for monitoring hydrogen applications).
-
Atmospheric Pressure Equalization (MPA Option): To ensure the injection of perfectly repeatable volumes regardless of the upstream pressure speed.
How It Works & Laboratory Integration
TGA / EGABOX Synchronization: Start your TGA run and EGABOX sequence simultaneously. Loops automatically capture gas fractions at target temperatures or mass-loss points.
Heated Storage: Gas fractions remain trapped at 200 °C without condensation or degradation.
Sequential Analysis: The automaton sequenced injections into the GC-MS Split/Splitless injector at its own pace. You get the complete kinetics of the reaction.
