To increase productivity, the VK 8020 automates both dissolution sample collection and HPLC injection. This system works in conjunction with the VK 8000, which can be used with most brands of dissolution equipment.
Samples are pulled using the motorized manifold to the collection tray. Between each sampling time point, as many injections as possible are made prior to the next pull.
Sample collection always takes precedence over sample injections. During a sample point, the injector module goes into standby mode, returning to its task only at the end of the time point.
You can program injection intervals from 1 to 99 minutes or wait for the ready signal from the LC. It is possible to inject standards before or after or bracket each group of samples.
The VK 8020 can be used as a collector only or HPLC auto-injector only at any time. You can independently program the number of standard injections to meet the USP system suitability requirements. The automated sampling manifold automatically lowers and raises sampling probes during the sampling cycle and the Peristaltic Pump transfers the samples from the vessels to the collector.
Features include:
- VK 8000 base station including sipper assembly with needle. See page 80 for a complete description of the capabilities of the VK 8000.
- VK 8020 injector module with Rheodyne 7710 valve and 20 μl loop.
