TAS is the abbreviation for Total Analysis System. It describes a chemical system that automates all for analysis necessary steps. (e.g. sampling, transport, filtration, dilution, chemical reactions, separation and detection) Chemistry (in Greek: χημεία) is the science of matter that deals with the composition, structure, and properties of substances and with the transformations that they undergo. ... Automation (ancient Greek: = self dictated) or industrial automation is the use of computers to control industrial machinery and processes, replacing human operators. ... Analytical chemistry is the analysis of material samples to gain an understanding of their chemical composition and structure. ...
A new trend today is creating Micro Total Analysis Systems - µTAS. Such a system shall shrink a whole laboratory to chip-size lab-on-a-chip. Due to being very small such a system can be placed close to a sampling site. It also can be very cost effective thinking of chip technologies, sample sizes and analysis time. Biochemistry laboratory at the University of Cologne. ... Lab-on-a-chip devices or micro-total-analysis-systems (µTAS) are single chips, usually constructed out of silicon or Pyrex glass, that integrate multiple traditional macroscopic laboratory processes, such as sample pre-treatment, reaction, and detection, on a smaller scale. ... A chip is a general term for a splinter or shard of something. ...
Fabrication of a demonstrator micro fluidic analysissystem (or µTAS = Micro TotalAnalysisSystem) containing a pressure-, temperature-, pH-, pO2 and PCO2-sensor for (bio-)chemical and (bio-)medical analysis.
The sensors used to demonstrate the technology are a capacitive pressure sensor, a temperature sensor, a pH ISFET and a chip containing the pCO2 sensor together with a pO2 sensor.
The flow system consists beside the carrier of 2 valves and a pump, connected by tubes.
