Abstract
The goal of this research was the construction of a capillary electrophoresis unit to be operated in the capillary zone electrophoresis mode to serve as a sensor for the determination of soil nutrients such as nitrate, nitrite, phosphate, calcium, magnesium and potassium. These nutrients are essential for successful farming and also have environmental implications. These analytes can be separated in less than two minutes under the conditions reported here. The results compare favorably with the corresponding data from a soil testing laboratory.
