Key features:
- Electron capture detector (ECD) with a low-energy electron source (63Ni)
- Designed for ultra-trace analysis of volatile and semi-volatile compounds that are challenging to analyse with other detector types (halogenated organic compounds, pesticides, nitro compounds).
- Qualitative analysis using standards (composition of reaction mixtures, reaction monitoring, kinetics).
- Quantitative analysis based on calibration curves, typically using the internal standard method.
