Abstract:
1. A device for quantitative analysis of a micro-volume solution, comprising: a base portion with a top surface, said base portion comprising a bottom fiber base for fixing a light-emitting fiber, said light-emitting fiber and said bottom fiber base forming a light-emitting surface for carrying a solution droplet; a movable arm with a bottom surface disposed above said base portion, said movable arm being capable of moving upwards and downwards and comprising an upper fiber base disposed at the position corresponding to said bottom fiber base for fixing a light-receiving fiber, said light-receiving fiber and said upper fiber base forming a light-receiving surface; at least one positioning block disposed selectively on said bottom surface of said movable arm, on said top surface of said base portion, between said movable arm and said base portion or the combination thereof; a light source for generating a light beam being coupled to said light-emitting fiber so that said light beam is transmitted to said light-receiving fiber from said light-emitting surface; and a filter module connected to said light-receiving fiber and coupled to a photo detecting module and a database in order, said filter module being capable of allowing light with the required wavelength to pass through; wherein said solution droplet forms an optical path with a constant length between said light-emitting surface and said light-receiving surface due to surface tension and adhesion when said movable arm moves downwards and clamps said positioning block between said movable arm and said base portion.
