8690-3000
- Holds 110 2 ml or 2.5 ml vials
- Interfaces with SRI and other GCs
- 15-Step automatic injection sequence
- Direct injection, no transfer lines
The HT300A Liquid Autosampler is made to meet the high throughput liquid injection needs of your GC analysis. Like the HT200H Headspace Autosampler, the swivel head design simulates the movements of manual direct injection and eliminates the need for transfer lines, as well as leaving the injection port free for manual injections. Up to 10 analytical methods, including function speeds, may be stored in the HT300A’s memory.
The automatic injection sequence may have up to 15 steps, which may be programmed to include:
- First sample of the group
- Last sample of the group
- Analytical method
- Number of injections for each sample
- Pre and post-washing solvent position
- Internal standard position (if used)
The sampling system eliminates air bubbles, and the variable fill speed allows for a wide range of sample viscosities. The syringe may be washed with solvent or sample.
