6.4 Extraction process
Each extraction procedure occurs according to a set of predefined operating parameters such as
pressure, temperature, flow rates etc. which are all part of the extraction method. The SpeedExtractor
can store up to 100 methods. The optional PC software SpeedExtractor Record allows to create and
manage an unlimited number of methods.
In order to guarantee reproducible conditions, it is recommended to make the instrument ready for the
extraction process as described in section 6.2, to prepare the samples in the meantime (section 6.2)
and start the extraction method as soon as the cells are placed in the heating element.
The following sections describe the individual stages of an extraction process, how to create, store
and open methods and how to optimize existing procedures.
6.4.1 Placing the cells and bottles/vials into the instrument
Fill the collection tray with empty vials and push it to
holding fixture.
The tray will automatically move upwards as the
extraction process starts. If 60 mL vials are used (P/N
049535) fix the vials with the optional retaining plate
P/N 11055205 (see also section 10).
If Syncore Analyst R-12/R-6 vessels are used fix the
vessels with the optional retaining plate P/N 11057054
for E-916/R-12 and P/N 11058339 for E-914/R-6 (see
section 10 for all available collection units and acces-
sories).
NOTE
The collection tray must be placed properly on the
instrument to start a method. It is not possible to start
a run in the absence of the tray.
Make sure to always fill the collection tray with empty
collection vials.
