Solid phase extraction is a time consuming procedure that requires careful and controlled handling. Performing SPE on large sample batches can be strenuous and prone to human error. In fact, majority of the time spent and errors during chemical analysis come from sample preparation. PromoChrom's automated SPE equipment can alleviate this problem by executing the steps unattended and with high repeatability and reproducibility. The open design makes it easy to place samples, solvents, cartridges and collection vials. Once that is done, all the user has to do is input the desired SPE steps and hit start. The simple interface allows users to choose which sample and solvent to use, as well as the flow rate and volume.
