Dionex RFC-30 Setup
For optimal suppressor performance, use the suppressor current
recommended for your target application. The setting to use depends on
several variables: the suppressor type, the column, the eluent type and
concentration, and the flow rate. The Dionex RFC-30 provides two
methods for setting the suppressor current:
•
Automatic calculation
:
With this method, you enter system information (EGC type,
suppressor type, flow rate, and eluent concentration) on the display
screens. The Dionex RFC-30 sets operating limits appropriate for the
system, and automatically calculates and sets the suppressor current.
See “Setting Up the Dionex RFC-30 for Automatic Current
Calculation” on page 24 for details.
•
Manual entry
:
With this method, you disable automatic calculation and manually
enter operating parameters. To disable automatic calculation, select
one of the following suppressor types:
AESXCALC
,
SRSXCALC
. See
“Setting Up the Dionex RFC-30 for Manual Current Entry” on
page 28 for details.
Table 3 summarizes the two setup methods.

Dionex RFC-30 sets
limits appropriate for the
selected EGC type,
suppressor type, flow
rate, and concentration.
Dionex RFC-30 calculates
the current range and sets
the current to the
recommended value. A
different value can be
entered, provided it is
within the calculated range.

Dionex RFC-30 sets
limits to the absolute
minimum and maximum
allowed for the type of
EGC and suppressor
(AES or SRS).
Current must be set
manually.
