摘要：
Supported liquid membranes, mounted in a flow system can be used for selective and efficient extraction and enrichment of various types of analytes prior to gas or liquid chromatographic analysis. They can also be used for integrating field sampling. The basis of the technique is described, together with environmental (acidic herbicides, amines and metal ions) and biological applications (to amines).
