A simple way to HPLC analysis
Our ERWEKA Dissolution HPLC On-/Offline System facilitates and automates the way to HPLC analysis.
After dissolution testing with the DT 720 and double filtration with the PVP 820 pump and the AFC 825, the medium is transferred to the HPLC sampler. There, the medium is first filled in a transfer block (PEEK block), and afterwards distributed into appropriate vials. If required, the samples can be diluted for immediate analysis or cooled and stored temporarily against UV radiation for later analysis.
The HPLC analysis starts as soon as a sample is filled into the HPLC valve of the sampler and a trigger signal is sent by the Disso.NET to the HPLC device. The analysis as well as the evaluation are done by the analysis software on a separate PC. As the analysis times of the samples are defined beforehand via the Disso.NET software, the sampler steadily passes the samples to the HPLC device (even after the termination of the release). Consequently, the dissolution test with HPLC analysis can be performed automatically without an operator (e. g. also at night). After the HPLC analysis, the results are displayed on a separate PC.
