DETECTION METHOD

摘要

The present invention relates to a method for the detection of at least one of a group of chemical species which method comprises: contacting an admixture of the group of chemical species with dry solid phase microbeads and allowing or causing the group to adhere onto the microbead surfaces to form coated microbeads, suspending said coated microbeads in a biologically acceptable vehicle and injecting them into a suitable animal host and recovering antisera from said host and utilising said so-formed antisera to bind to any one of said group in a sample; preferably the group of chemical species include polyhalogenated aromatic hydrocarbons such as PCBs. The invention also provides a method for removing such chemical species from the liquid stream.
