When developing a new extraction method, select a solvent or solvent
mixture that has a high solubility for the analytes of interest, but not
for the sample matrix. If you have been using another extraction
method (Soxhlet, for example), use the same solvent with the ASE
100 that you used with the other method.
_
Before running a preprogrammed method, refer to Section 2.5 for the
recommended solvent.
_
Use HPLC- or pesticide-grade solvents.
_
Use organic or aqueous solvents.
_
Use single- or multiple-component solvents.
_
Weak acids and bases (pH >2 or pH <11) or other noncorrosive
additives can be used, but add them in small percentages (<5% by
volume) to the solvent system. Do not use nitric, hydrochloric, or
sulfuric acid with the ASE 100.
_
Solvents do not generally need to be degassed. Degas solvents only if
the analyte of interest oxidizes easily.
Verwenden Sie keine Lösungsmittel, deren
Selbstentzündungstemperatur bei 40° bis 200°C liegt. Die
untenstehende Tabelle zeigt einige Lösungsmittel, die Sie nicht
mit dem ASE 100 verwenden sollten. Bei Fragen zur Eignung
von Lösungsmitteln wenden Sie sich bitte an Dionex.

After extracting with acidic solvents or basic solvents, rinse
the system with either 100% organic solvent (e.g., acetone or
methanol) or distilled water before overnight shutdown.
Do not use acetone if the O-ring on the outside of the
extraction cell cap is Viton (black).
