The invention discloses an on-line
coupling system for a dynamic liquid-
liquid solid imprinted microextraction-
liquid phase chromatogram, which comprises a magnetic
agitator, a water bath
bottle, an extracting
bottle, a draft tube, a
peristaltic pump, a high-pressure six-way switching valve, a molecularly imprinted
solid phase extracting material, a high-pressure six-way sample valve, a quantifying cup, a sample needle, a
liquid phase chromatographic pump, a
chromatographic column, a
detector, a
liquid phase chromatogram and the like. Through the
coupling of a dynamic liquid-
liquid solid imprinted microextracting device and the liquid phase chromatogram, the on-line overall processes of the preenrichment, the extraction, the
desorption, the separation and the detection of a target analytein a water phase sample are achieved. By using the
system, the universality of liquid-liquid extraction, the
high selectivity and the high enrichment capability of a molecularly imprinted
solid phasemicroextraction technique, the efficient separation capability and the high sensitivity of the liquid phase chromatogram are combined; the analysis degree of
automation is improved; the analysis timeis shortened; the accuracy and the precision are improved; and the
system can be effectively applied to the analysis and the detection of a trace
organic matter in a complicated sample.
