    The number of samples that a rack can accommodate depends on the diameter of the sample beakers. • With the 838 Advanced Sample Processor all of the Metrohm- sample racks with 42 cm diameter can be used. These are also us- able with the Sample Processor models 778 and 814.

    This ensures that the beaker positions coincide with the inter- nal position table of the current rack. The standard racks supplied by Metrohm are already provided with a predefined magnet code for each type of rack. If several racks of the same type are in use then the magnet pins can be arranged differently to allow the unambiguous identification of each individual rack.
  • Page 74 Rack codes can be altered as required. However, they must always be assigned to a single rack only. Avoid the use of the predefined codes for the standard racks supplied by Metrohm, see also p. 64. The working position is used for defining the lift position at which a sample is to be processed.
