Automated Solid Phase Extraction

The HT400E autosampler can reliably and accurately automate manual Solid Phase Extraction procedures and automatically injects the sample into an HPLC system. This allows increased work flow and removes the need for many repetitive tasks.

The HT400E can use up to 11 different solvents (4 as standard) to activate cartridges and wash and elute samples in up to 4 different fractions. It has separate valves for syringe washing and can also add reagents to the eluent before injection.

The exceptionally high flow reproducibility and ‘zero dead volume’ plunger design ensure the best method for reproducibility and consistency.

Even very complex methods can be automated, with samples extracted, treated further and then re-injected onto another SPE cartridge for further operations. The multiple position capability of the HT400E makes it incredibly flexible and yet very compact with minimum bench space requirements.

A simple change of the sample tray and the HT400E becomes a fully functional HPLC autosampler for up to 110 samples.
