A method of robotically carrying out microchannel chemical analysis uses a loading station (90), wherein a loading device (77) picks up samples from the sample walls of a casette (85), and then delivers them to the inlet ports of the microchannels of a microchip in a microchip station (83). The microchip is then moved to an analysis station, where electrophoretic separation is performed. At the same time, a new microchip can be loaded at the loading station (90).
