3.2 Editing a Custom Method (1–24)
If the ASE 100 preprogrammed methods (see Section 2.5) are not suitable for a
particular extraction, edit one of the 24 custom methods provided with the system.
All parameters in these methods are initially set to their default values. You can
create a new method by editing either a custom method that still contains the
default parameters or a custom method that you previously edited. The edited
method can be saved to a new method number, if desired.
Before beginning, review the method development guidelines in Section 3.3. For a
list of the values allowed for method parameters, see Table 3-3.
Parameter Function Value Range
TEMPERATURE
Temperature at which to heat the 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,
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. We recommend 40 to 80 seconds for
a 10 mL cell, 70 to 110 seconds for a 34 mL
cell, 160 to 200 seconds for a 66 mL cell, and
250 to 290 seconds for a 100 mL cell. 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)
