Lead analysis method and analyzer using fluorescent chromoionophore

摘要

The present invention relates to a lead analysis device and method using the fluorescent ion recognition substance. In particular, the lead and a combination of a fluorescent compound to an optional ion recognition substance binding to the light fluorescence measurement by relating the analysis apparatus and method which can improve the detection limit of the quantitative analysis of the lead by using a small amount of sample will be.; Lead analyzer sample inlet and a reagent inlet using a fluorescent ion recognition material of the present invention; Microbead structure in having a first cross-sectional area in the region which the sample inlet and the reagent inlet combined; Measuring section of the channel is connected to the micro-bead formations second cross-sectional area larger than the first cross-sectional area; A detector located in the upper center of the channel; And it has a technical feature in yirueojim light emitting portion is located a predetermined distance spaced apart from the detectors.; Accordingly, the quantitative analysis of the lead by using a small amount of the sample lead analysis apparatus and method using the fluorescent ion recognition material of the present invention by measuring a combination of a fluorescent compound to the ion recognition substance binding to the lead and selective light fluorescence there is an effect that it is possible to improve the detection limit. That is, the measuring apparatus of the present invention is an analysis apparatus in a compact apparatus using a MEMS and the micro-fluid dynamics, can reduce the size than the conventional heavy metal analysis equipment dramatically, and increase the limit of detection with only a small amount of the sample to the ppb or less. It also has a low power, a very large advantage as environment-friendly device.
