Abstract
A test device having a micro flow channel including a reaction part where a reactant that is reactive to a tested chemical dispersed in a tested fluid is fixed, and at least one actuator for actuating the tested fluid to move in at least one of two opposite sides of the micro flow channel so as to homogenize a density distribution of the tested chemical in the tested fluid. The tested fluid is sent in the micro flow channel a plurality of times.
Claims5
A reactive test method comprising:
- sending a tested fluid in a micro flow channel a plurality of times, the micro flow channel disposed oriented horizontally, the micro flow channel including a reaction part having a reactant fixed to a bottom of the micro flow channel thereat, wherein the reactant is reactive to a tested chemical dispersed in the tested fluid;
- actuating the tested fluid to move in at least one of two opposite sides of the micro flow channel so as to homogenize a density distribution of the tested chemical in the tested fluid, and
- stirring, via one or more of an oscillator, a resonator, or a spiral groove formed in the micro flow channel, the tested chemical and the tested fluid, wherein the oscillator, the resonator, or the spiral groove is disposed in at least one of two opposite sides of the micro flow channel.
