As awareness of the effects of even ultra-trace contamination in the environment grows, there is an
increasing demand for better analytical methods in studying environmental samples. For instance,
new regulations by agencies in North America [1] and Europe [2] have forced laboratories to adopt
methods with lower limits of detection, greater specificity, and higher precision for environmental
agents. The analysis of environmental samples is complicated by the fact that the selected technique
must deal with a wide range of analytes and matrices. Immunoaffinity chromatography (IAC) is one
method that has recently been used for this purpose.
