The HT280T is a single unit combining static headspace analysis, liquid sample injection and SPME (solid phase microextraction).
As the successor to the HT250D, the HT280T combines the operations of the HT200H Headspace Autosampler and the HT300A Liquid Autosampler, with the addition of SPME.
The HT280T is compatible with almost all GC and GC/MS systems, both present and past. It claims it can save you time and money, increase analysis flexibility and save older GCs from redundancy.
Changing between liquid, headspace and SPME modes takes about 5 minutes and there's no need to remove the sampler from the GC.
Headspace operation key features:
- No transfer lines
- Rotating head design leaves injection port free for manual injection
- Progressive sample transfer
- May be configured for left or right operation
- Gas flush of syringe between injections
Liquid sampler operation key features:
- No transfer lines
- Syringe may be washed with solvent or sample
- Injections may be made on two columns (high throughput and confirmation mode)
- Rotating head design leaves injection port free for manual injection
- Internal standard sampling
- Memory stores 10 different methods
- Variable fill speed allows for wide range of sample viscosities
- Sampling system eliminates air bubbles
- Programmable sampling and injection speed
SPME operation key features:
- Single step extraction (reduces sample preparation time by up to 70%)
- Minimal use of solvents
- Programmable extraction depth to perform both headspace and liquid extraction
- Oven door kept closed during extraction to keep temperature constant
