Title:
ANALYZER
Document Type and Number:
WIPO Patent Application WO/1999/064846
Kind Code:
A1
Abstract:
An analyzer characterized by comprising a chip and a detector, wherein the chip is an organic polymer member having a fine capillary through which a fluid sample or a fluid sample and a fluid reagent flow and can perform a chemical reaction on the sample in the capillary without using a separate weighing means, and the detector is a photo-thermal conversion detector for measuring a physical quantity change such as a refractive index change caused by a partial temperature change of the sample and the reagent by applying an excitation light to a substance to be measured produced by the chemical reaction, thereby providing a small analyzer excellent in chip waste-disposal, capable of analyzing inexpensively, simply and in a short time and being suitable for a POC analysis.
