Total Analysis System

With Total Analysis System, a device is described that performs automated everything needed to (chemical) analysis of a substance steps. For example, the sampling, transportation, filtration, dilution, chemical reaction, separation, and detection and evaluation include.

Assumes particular importance of this concept in the context of μ -TAS, "micro total analysis system " (micro total analysis system ). The structures of these systems are shrunk to micrometer size. The aim is to achieve an analytical laboratory in chip size ( " lab-on -a-chip "). Such would be cheap to produce, other functions could include and require only a tiny amount of the substance to be analyzed.

The term μ -TAS was coined in 1990 by scientists at Ciba -Geigy AG (Basel).
