Portable Liquid Chromatography System Based on Battery-powered Electroosomotic Pump and Microchip with Packed Column and Electrochemical Detector
نویسندگان
چکیده
We present a compact and lightweight liquid chromatography system. This system consists of a battery-powered electroosmotic flow pump, a 20-nL injector, a microchip contains a reversed phase packed column and an electrochemical detector, and a handheld potentiostat powered by a universal serial bus (USB) connected to a laptop computer. The system has overall dimensions of approximately 26 cm wide × 18 cm deep × 21 cm high and its weight is 2 kg. With the present system, various electroactive compounds, such as catecholamine, were successfully separated.

Ornamental fish ponds requires continuous control of water quality such as salt content (salinity), hardness (Ca, Mg), and ionic contents particularly nitrate and ammonium. Conductivity is considered as a parameter correlates with these parameters and sensitive to environmental conditions such as temperature. Therefore, a conductivity detector can be employed for control of water quality in aqu...
