1 Introduction
The 845 Eluent Synthesizer and its associated «Mix Control» soft-
ware can be used for the fully automatic preparation of solutions and
mixtures such as eluents, mobile phases, buffer solutions or standards
with the required concentration and component ratios.
The 845 Eluent Synthesizer is based on the Dosino technology which
allows high-precision dosing to be carried out. Both aqueous (acidic or
basic) and organic mixtures can be prepared. The system (with an op-
tional extension) can also be used to adjust the pH.
1.1 Instrument description
Two versions of the instrument are available :
• 2.845.0010 845 Eluent Synthesizer with one Dosino
• 2.845.0020 845 Eluent Synthesizer with two Dosinos
The 2.845.0010 Eluent Synthesizer with one Dosino can be used to mix
together three components (of which one is the main component).
The 2.845.0020 Eluent Synthesizer with two Dosinos can be used to
mix together five components (of which one is the main component).
Both versions contain a built-in magnetic stirrer The software «Mix Con-
trol» is supplied with the instrument.
The 2.702.0120 Eluent Synthesizer Package for the automatic pH ad-
justment is offered as an option. In addition to a 702 Titrino this also
contains an Aquatrode, a 10 mL exchange unit and a Remote Box (see
Section 5.2.3).
The 845 Eluent Synthesizer is connected to a PC via a USB and ope-
rated with the «Mix Control» PC software provided. The operation of the
software is described in the online help and in Section 3 of these In-
structions for Use.
