HTA HT300A Liquid GC Autosampler

The HT300A is a GC autosampler made to meet the liquid injection needs of your Gas Chromatography analysis. A simple, elegant, reliable and economical way to extend the life of your existing GC!

The autosampler is compatible with all major brands and model of GC including those from Agilent, PerkinElmer Shimadzu, Varian, and many more.

The HT300A autosampler is configured with a 10 position fixed (HT310A) tray.

Syringes of 1 to 100µl may be used and with the option of a special large injection version, this can be increased to 1000µl per sample.

Key features:

• 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

The HT300A is easily installed on all major GCs. The tray can be mounted on either side.

Easy setup and operation:

The instrument can be controlled by the user-friendly integrated keypad, or by a PC using the HT-COMSoft Software.

The automatic injection sequence may have up to 15 steps that 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).

Multi-vendor compatibility:

The HT300A is compatible with the HP5890 and HP6890 GCs, and with all other major models of GC. If you upgrade an old autosampler to the HT300A and the GC is changed later on, the sampler has the ability to migrate to any new GC type and is therefore a very cost-effective option.

The same is true with chromatography data systems. The HT300A is fully compatible with Chemstation ®, EZChrom Elite and DataApex Clarity.

Internal standards:

Internal standards are used to ensure analyses are accurate and make allowances for any variations in the GC performance. The internal standard should have a predictable retention time (that is completely resolved from the rest of the sample) and should make up a known amount of the total sample injected.

Using internal standards on the HT300A is simple and does not require any samples to be measured or weighed. The volumes of the internal standard and the sample are entered into the method. The sampler first pulls up the internal standard, then inserts an air gap to prevent mixing, followed by the main sample. In this way it is easy to ensure that a defined proportion of the injected sample is made up using the internal standard.
