An integrated microfluidic chip, wherein at least one integrated reaction unit is provided on its substrate, and the integrated reaction unit comprises at least a sample cell (1), a mixing cell (2) and a reaction cell (3) connected through liquid channels (6). In one aspect, one end of the sample cell (1) is provided with a sample inlet (4), and the chip further comprises an internal air circulating system/circuit. One end of the internal air circulating system/circuit is connected with the mixing cell (2), while the other end comprises at least a first circulation branch circuit connected with the end of the sample cell (1) distal to the sample inlet (4). |
