View source for Total analysis system

The term '''total analysis system''' ('''TAS''') describes a device that combines and [[automation|automates]] all necessary steps for the chemical [[analytical chemistry|analysis]] of a sample (e.g., sampling, sample transport, [[filtration]], dilution, chemical reactions, separation, and detection).<ref>{{Citation |last=Justino |first=Celine I.

Total analysis systems are designed to shrink the processes carried out in a [[laboratory]] to a chip-sized [[lab-on-a-chip]]. Due to this, it can be more cost-effective to carry out complex tests when considering [[Integrated circuit|chip]] technologies, sample sizes, and analysis time. Total analysis systems can also reduce the exposure of [[Toxicity|toxic]] chemicals for lab personnel. This technology can also be used in [[point-of-care testing]] or point-of-use diagnostics, which do not require skilled technicians.<ref name=":0" />
