| Abstract: | The use of a magnetic particle based enzyme immunoassay for the analysis of atrazine is presented. The scope of the test is between 0.04 and 5 ppb. The assay is easy to perform and the results are obtained in less than an hour. Coefficients of variation below 10% were achieved. Soil and water samples were analyzed, the latter ones without clean-up. No interferences of the sample matrices could be found. Comparison of atrazine concentrations determined by the magnetic particle based assay, a microtitre plate assay, and GC showed good correlations. The presented assay can be used as a rapid and sensitive screening method for water and soil samples. |
