Abstract
Substantial fraction of herbicides used in the agriculture reaches the soil, an environmental compartment where these substances are liable to processes of adsorption, degradation, leaching, etc. The control of environmental quality requires efficient and low cost analytical methods. After sampling, sample treatment processes including extraction, pre-concentration and elimination of inte…

Abstract
Sequential injection chromatography (SIC) is a relatively new technique of separation based on coupling systems of sequential injection analysis (SIA) with monolithic stationary phases. These phases are bimodal structure of micro and meso pores allowing the flow of mobile phase at pressures much lower than those usually required with the use of packed columns. Therefore, the SIC system al…
