Graphitised Carbon Blacks
These are non-specific carbon sorbents, widely used for trace-level applications due to their minimal artefact levels, although they’re less suitable for some labile or highly reactive species.
- Carbograph 2TD – A very weak sorbent, suitable for alkylbenzenes, hydrocarbons to n-C20 and semi-volatiles.
- Carbograph 1TD – A widely used ‘general-purpose’ sorbent, often used in two- or three-bed sorbent tubes.
- Carbograph 4TD – A medium-strength sorbent suitable for light hydrocarbons.
