Column and Stationary Phase
⚠️ To be completed — column type installed, dimensions, stationary phase
Injection Modes
The GC-2025 supports three injection modes via the SPL unit — see Split_vs_Splitless_Injection for detailed theory and selection guidance:
- Split — for high-concentration samples
- Splitless — for trace-level analysis
- Direct — used only for SPL leak checks

How It Works
The GC-2025 uses two fundamental principles:
- Gas chromatographic separation — compounds partition between a carrier gas and a stationary phase inside a column, eluting at characteristic retention times → GC_Separation_Theory
- Flame ionization detection — eluting compounds burn in a hydrogen/air flame, generating ions measured as electrical current → Flame_Ionization_Detection
