The invention discloses a
concentration response type biochemical multi-component online analyzer. The
concentration response type biochemical multi-component online analyzer comprises a multi-component concentration detection module, a precise sampling mechanical arm, a multi-
channel data acquisition module, an automatic sampling module and a multi-channel flow path structure; the multi-componentconcentration detection module is composed of a detection
pool, a
sample pool, a sampling
pool, a cleaning
pool and a waste liquid pool, and can realize online detection on multi-component concentration; the sampling mechanical arm is composed of a two-freedom-degree mechanism arm, a precision
syringe and a sample injection needle, and realizes precise locating sampling control on the detection pool; the multi-
channel data acquisition module is composed of an embedded development board and a touch screen, and realizes online detection, display and storage on the multi-component concentration;the automatic sampling module is composed of a precision membrane sampler, a miniature vacuum
diaphragm pump and a stop valve; and the four parts are linked and assembled through a multi-channel flowpath integrated structure. According to the
concentration response type biochemical multi-component online analyzer disclosed by the invention, online real-time detection on multiple substrates, keyintermediate metabolites and product concentrations in a microbial
fermentation process can be realized; the structure is compact; and
batch production is conveniently carried out.
