1 Introduction
1.1 Field of application
The 858 Professional Sample Processor is an instrument with many appli-
cations that was conceived for preparing samples for ion chromatography.
Inline filtration, dialysis, preparing dilutions, sample preconcentration,
inline calibration, partial loopfill, etc. are techniques that can be used with
the 858 Professional Sample Processor without any problem. The entire
array of sample preparation techniques can be automated in time-saving
manner.
Thanks to its proven USB interface, the 858 Professional Sample Processor
can be flexibly linked into the Metrohm instrument systems. The control of
the instrument is always accomplished thereby by means of a high-per-
formance PC software, e.g. MagIC Net from Metrohm.
The equipment with a Swing Head with a robotic arm makes it possible to
approach any given point on a sample rack. As a result, the number (maxi-
mum 999 rack positions) and sequencing of the samples on the sample
rack is almost completely unlimited. Customer-specific special racks for
individual requirements can be fabricated upon request.
1.2 Instrument description
The 858 Professional Sample Processor has the following characteristics:
￭ Turntable with interchangeable sample rack. The prefabricated sample
racks can hold various numbers of different vessel types and sizes. Any
number of reserved special positions can be defined on the rack.
￭ Tower with load-bearing lift. The lift contains a precision drive with
robotic arm as a receptacle for a needle holder or other working
heads.
￭ Three MSB connectors (Metrohm Serial Bus), each for controlling one
800 Dosino, one 801 Magnetic Stirrer, one Remote Box, etc.
￭ Two USB connectors, through which e. g. printers, keyboards, barcode
readers or additional devices such as Dosing Interfaces, etc., can
directly be connected
￭ Two connectors for a peristaltic or a membrane pump
￭ Stirrer connector on the tower, for rod stirrer or magnetic stirrer
Depending on the model:
￭ Two-channel peristaltic pump
￭ Returnable injection valve
