MICRO FLUIDIC CHIP FOR HEAVY METAL ION SAMPLE PRETREATMENT, AND APPARATUS AND METHOD FOR PRETREATING HEAVY METAL ION SAMPLE USING THE SAME

摘要

The present invention relates to an analysis technology of a heavy metal ion sample and, more specifically, relates to a microfluidic chip for heavy metal ion sample pretreatment, and an apparatus and a method to pretreat the heavy metal ion sample using the same. According to the present invention, the microfluidic chip for heavy metal ion sample pretreatment comprises: a body part having a capture chamber filled with cation exchange resin, and a flow channel to guide a liquid sample containing heavy metal ions to the capture chamber; a membrane part to cover and block an upper part of the flow channel; and a cover part to cover a membrane part. In the flow channel, a blocking wall to block flow of a fluid is prepared. Moreover, a pressure action groove located to correspond to the blocking wall is prepared on a surface in contact with the membrane part of the cover part; thereby providing the microfluidic chip for heavy metal ion sample pretreatment.
