Green micro total analysis systems (GμTAS) for environmental samples

Micro total analysis systems (mu TAS) which have received great interest in the recent years and successfully employed for fluid processing in microchannels at microliter levels are powerful alternatives to traditional macroscale analytical systems. Unique benefits arise in the scaling down of traditional macroscale systems, including significant decrease of reagent, sample and energy consumption, faster and cost-effective analytical processes and lowered analysis time. Furthermore, mu TAS can be efficiently automated which leads to higher throughput and multiplexing. In this review paper, mainly green aspects of mu LTAS such as reducing of the volume of sample and solvents, using green solvents in mu TAS, minimization of the generated waste and cost-effective processes for mu TAS are discussed. The recent applications of green mu LTAS in the detection of various pollutants including heavy metals, pharmaceutical compounds, and dye compounds in environmental samples such as wastewaters, river waters are also demonstrated and highlighted.

Automated summary

Micro total analysis systems (μTAS) offer significant advantages over traditional macroscale systems, including reduced energy consumption, faster and cost-effective analytical processes, and shortened analysis time. Furthermore, automation and high throughput capabilities of μTAS can further enhance efficiency.
