Patent ID: 8603414

Claim:
A micro-chemical analysis device, comprising: a detachable micro-cassette including a sample storage unit containing an original sample, a reagent storage unit containing a reagent, and an additive storage unit configured to store an additive; and an analysis device configured to receive the detachable micro-cassette containing the original sample and the reagent, wherein the analysis device includes a liquid control unit configured to cause the original sample contained in the sample storage unit to be transferred to a sample processing unit of the micro-cassette through a sample channel, and to cause the additive stored in the additive storage unit to be transferred to the sample processing unit of the micro-cassette through an additive channel; the micro-cassette includes the sample processing unit configured to mix the additive to the original sample to form a waste component that negatively affects analysis of the original sample so as to obtain a first sample and the waste component, the mixing of the additive and the original sample being controlled by the liquid control unit of the analysis device; and an isolation unit configured to separate the waste component from the first sample to produce an isolated second sample; and the analysis device further includes a data processing unit configured to produce analysis data indicative of a component of interest included in a mixture of the isolated second sample and the reagent.
