Features of TRACE
- Simple, rugged hardware
- Internal LAN interfacing capability
- Independently heated valve housing able to accommodate up to 4 heated/2 unheated gas valves, 8 pressure regulators, 8 needle valves, In/out ports, packed and capillary columns
- Range of Large Volume techniques overcomes sensitivity boundaries of conventional GC
- Linear heating rate up to 1200°C/min. reduces sample run times for crude oils, pesticides and hydrocarbons determination as well as food and flavor characterizations
- High temperature programming up to 20°C/s and fast cooling times of approximately one minute
- Precise retention time control
- Large Volume split/splitless technique using standard splitless injector extends sample injection volume of conventional GC methods without additional investment, training or revalidation of methods
- Supports range of injectors, including BEST PTV, cold on-column inlets and detector soltuions for conventional GC and GC/MS
- Provides in-series, staked or parallel configurations of up to three detectors featuring different selectivity
- Dedicated turnkey analyzers for chemical and petrochemical applications available
