FLUORESCENCE DETECTION DEVICE

PROBLEM TO BE SOLVED: To easily detect each of allergen containing substances different in a size.SOLUTION: A fluorescence detector (1) comprises a branch unit (4) that causes sucked allergen-containing substances to be branched to branch route parts (5) different in accordance with the sizes of the allergen-containing substances. In at least two of the branch route parts (5), a detection unit (6) is provided that detects fluorescence emitted by the allergen-containing substance within the branch route part (5) by irradiating the interior of the branch route part (5) with excitation light.SELECTED DRAWING: Figure 1 【課題】大きさの異なるアレルゲン含有物質のそれぞれを、簡便に検出する。【解決手段】蛍光検出器（１）は、吸引したアレルゲン含有物質を、該アレルゲン含有物質の大きさに応じた異なる分岐経路部（５）に分岐させる分岐部（４）を備えるとともに、上記分岐経路部（５）内に励起光を照射して該分岐経路部（５）内の上記アレルゲン含有物質が発する蛍光を検出する検知部（６）が、上記分岐経路部（５）の少なくとも２つに設けられている。【選択図】図１
