  • Page 26: Operation

    Depending on the size of the sample tubes and the desired lift height for the suction of the sample solution the work position for the needle has to be set before starting a sample series. Read the following pages to learn how to configure the 813 Com- pact Autosampler. 813 Compact Autosampler...

  • Page 27: Configuration

    Triple injection of each sample, no air gap, the needle re- mains in the sample during the determination. Before running the 813 Compact Autosampler for the first time, the work position of the lift has to be set correctly. The work position defines the position of the suction needle while aspirat- ing the sample.
