Double the speed of bioanalysis using a 10-port valve

By using a 10-port valve faster bioanalyses can be achieved. By connecting two BioTrap 500 columns in a 10-port valve (2-position), it is possible to handle two samples simultaneously. Fig. 7 shows the connection of two BioTrap 500 columns and one analytical column in one HPLC system.

In the first position, the sample is extracted on BioTrap 500 column 1, while the previous sample is back-flushed with the analytical mobile phase from BioTrap 500 column 2 onto the analytical column. In the second valve position, the sample extracted on BioTrap 500 column 1 is back-flushed onto the analytical column, while the next sample is injected onto BioTrap 500 column 2 for extraction.
