Abstract
Polyamide sample preparation tubes with a hollow polyamide tube and an extraction medium contained within the tube are utilized in the sample preparation devices. The sample preparation tubes are substantially inert and show little tendency to dissolve or leach contaminants into nonaqueous liquids. The polyamide tubes may be used in preparing samples for analytical procedures such as GC, GC/MS, LC or LC/MS.
