GC-Autosampler
HT200H 40-Vial Headspace Autosampler
- Interfaces with SRI and other GCs
- Holds 40 Standard 20mL Headspace Vials
- Injects directly into the GC – no transfer lines
- 6 Position Incubator with Orbital Shaking
- Progressive Sample Transfer
The HT200H Headspace Autosampler is designed to meet the requirements of static headspace injection for GC analysis. The swivel head design simulates the movements of manual direct injection and eliminates the need for transfer lines.
The injection tower smoothly transports the vials to
the six position incubator, where they are orbitally agitated at the
user-programmed temperature. The heated syringe then samples the
headspace and injects directly into the GC. The 2.5 or 5mL syringe is
purged with inert gas after injection. The incubator oven and the
heated syringe have the same programmable temperature range of 4-150oC.
The rotating design leaves the injection port available for manual
injections at any time. The HT200H processes samples so that headspace
injections start immediately after the previous run is completed.
Up to 10 analytical methods, including all the user-selected options listed in the OPERATING SPECIFICATIONS table, may be stored in the HT200H memory.

HT280T Headspace, Liquid and SPME Autosampler
The HT280T is a single unit combining static headspace analysis, liquid sample injection and SPME (Solid Phase Microextraction)!
As the successor to the hugely popular HT250D, the HT280T effectively combines the operations of the HT200H Headspace Autosampler and the HT300A Liquid Autosampler, with the addition of SPME.
Consider that the HT280T is compatible with almost all GC and GC/MS systems, both present and past, and you have a truly remarkable development in GC autosampling.
The HT280T can save you time and money, increase analysis flexibility and save older GCs from redundancy. Changing between liquid, headspace and SPME modes is very simple. It takes about 5 minutes and there's no need to remove the sampler from the GC.

Headspace Operation
The system is uses a heated syringe to extract headspace samples from the 6 position orbital oven/shaker. This eliminates tubing, dead volume and sample absorption. Vial transport is positive and incredibly reliable – the system constantly checks that vials are present and are located in the correct place. No expensive magnetic caps are required. No transfer lines are required and the unit mounts directly on the GC thus reducing bench space requirements.
Operation is via the simple keypad or by HT-COMSoft software. Up to 40 headspace vials of 20ml or 10ml may be stored in the standard tray. Progressive sample preparation means that samples are automatically loaded into the oven at the correct time to ensure an injection is ready as soon as the previous run is complete, maximizing your GC efficiency.
Key Features:
Liquid Sampler Operation
Up to 110 samples may be processed as single or batch injections using one or more analysis methods. Any 12x32mm vial may be used with any cap type. All parameters from the sampling depth through to the injection speed, depth and dwell times may be programmed through the front panel or via the HT-COMSoft software
The automatic injection sequence may have up to 15 steps which can be programmed to include:

SPME Operation
SPME is a unique sample preparation technique that eliminates most of the drawbacks associated with extracting organics. SPME requires no solvents or complicated apparatus.
SPME has gained widespread acceptance as the technique of preference for many applications including: flavours, fragrances and contaminants in food; forensic and toxicology applications; environmental and biological matrices; organic volatiles in pharmaceutical compounds. Automated SPME with the HT280T delivers more accurate results with greater throughput than manual SPME.

Automated SPME with the HT280T delivers more accurate results with greater throughput than manual SPME.
The HT280T can extract volatile and non-volatile compounds in both liquid and headspace samples using
variable vial penetration depth. Samples can be derivatised pre or post-extraction as the application requires.
The extraction is performed by exposing the fibre into the sample vial. Samples can be agitated by orbital rotation
and heated during extraction.
Both the shaking speed and oven temperature are programmable. The oven door is kept closed during extraction to maintain constant temperature. After the compounds have been thermally desorbed in the GC injector, the fibre may be fully cleaned again in the optional heated fibre cleaning station positioned at the back of the unit.
