System configuration for the injection of samples with automatic solid phase extraction with a single binary pump system to operate in the field of HPLC, ultra-, micro- and nano-HPLC.
System configuration for the injection of samples with automatic solid phase extraction with a single binary pump system to operate in the field of HPLC, ultra-, micro- and nano-HPLC.
The invention relates to a system with specific valves for loading the sample onto a pre-column for purification, concentration, transferring and separation on an analytical column with only a binary high-pressure HPLC pump system, which for transferring the sample from the injection loop on the precolumn , is used for transferring the sample from the guard column to the analytical column, for washing and conditioning the precolumn and analytical column and for the analytical gradient, without the flow is interrupted through the analytical column.
