HT250D Duet — Headspace and Liquid Autosampler in one unit

HT250D Duet Headspace and Liquid AutosamplerTwo Autosamplers — One Unit!

The HT250D is a single unit combining Static Headspace analysis with traditional liquid sample injection at a price not much more than the headspace unit alone!

Consider that the HT250D is compatible with most GC and GC/MS systems, both present and past, and you have a truly remarkable development in GC autosampling that can save you time and money, increase analysis flexibility and save older GCs from redundancy.

Changing from Liquid to Headspace is as simple as changing the sample tray, syringe and vial sensor — about 5 minutes in total without the need to remove the sampler from the GC.

The HT250D effectively combines the operation of the HT200H Headspace autosampler with the HT300A Liquid autosampler in a single unit of the same dimensions as the HT200H. The system is supplied with a conversion kit, allowing the user to switch from headspace to liquid operation.

Headspace Operation

The system is supplied with a heated syringe to extract headspace samples from the 6 position orbital oven/shaker. 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, 20ml or 10ml headspace vials may be stored in the standard tray.

Key Features:

• No transfer lines means no sample crossover
• Rotating head design leaves injection port free for manual injection
• Progressive sample transfer means samples always ready when previous run completed
• May be configured for left or right operation
• Gas flush of syringe between injections

Liquid Autosampler Conversion

The user can simply change the operation of the autosampler from headspace to liquid at any time. A conversion kit is supplied which includes a 110 position sample tray for 2ml vials, wash and waste vials, 10µl syringe kit and sensor for 2ml vials. Just one simple tool (supplied) is required for the conversion which takes around 5 minutes to complete with the autosampler in situ.

The autosampler automatically detects the tray type and the on-board software switches modes from headspace to liquid.

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 Windows™ software

The automatic injection sequence may have up to 15 steps which can be programmed to include:
• First sample of group
• Last sample of group
• Analytical method
• Number of injections for each sample
• Pre- and Post-washing solvent position
• Internal Standard position (if used)

Key Features:

• No transfer lines means no sample crossover
• 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
