2.4 Method Control
A method defines all of the timed events that occur during a sample extraction (see
Table 2-2). There are two types of methods:
_
Preprogrammed methods are application-specific methods created by Dionex.
These methods cannot be changed or deleted by the user. For a list of the
parameters for each preprogrammed method, see Section 2.5.
_
Custom methods are customer-programmable methods. All custom methods
initially contain the default method parameters. These methods can easily be
modified (i.e., customized) by the user as required. For instructions on how to
edit a custom method, see Section 3.2.
Parameter Function Value Range
TEMPERATURE Temperature at which to heat the extraction cell. Off, 40 to
200
° C
(default=100)
STATIC TIME Static solvent extraction time. 0 to 99 min
(default=5)
FLUSH
VOLUME Amount of solvent to flush through the
extraction cell after the static heating step. The
FLUSH VOLUME is expressed as a percentage
of the cell volume; for example, if the
FLUSH
VOLUME
is set to 50%, 5 mL is flushed through
a 10 mL cell, 17 mL is flushed through a 34 mL
cell, and so on.
0 to 150% vol
in 5% incre-
ments
(default=60)
PURGE TIME Amount of time the cell is purged with nitrogen. 20 to 900 sec
(default=100)
STATIC CYCLE Number of times the static heating and flushing
steps are performed. When more than one cycle
is specified, the flush volume is divided among
the cycles. 1 to 5
(default=1)
