| Abstract | |
A compact environmentally friendly microcontrolled microfluidic device ideal for in situ phosphate determination was developed based on a microsystem based on low-temperature co-fired ceramics (LTCC) coupled to a light-emitting diode (LED)-photometer with a multicommutation flow analysis (MCFA) approach. The experimental parameters of the MCFA analyzer were optimized by chemometric studies. Under the best experimental conditions, limits of detection and quantification of 0.02 mg P L-1 and 0.07 mg P L-1, respectively, and a sampling frequency of 67 h(-1) were estimated. Moreover, a low sample consumption of only 60 mu L per determination was the other advantage that fully meets the requirements of sustainable research and green chemistry purposes. (AU) | |
