|Use:||Field screening of individual contaminants.|
Immunoassay technology relies on an antibody that is developed to have a high degree of sensitivity to the target compound. This antibody's high specificity is coupled within a sensitive colorimetric reaction that provides a visual result. The intensity of the color formed is inversely proportional to the concentration of the target analyte in the sample. The absence/determination is made by comparing the color developed by a sample of unknown concentration to the color formed with the standard containing the analyte at a known concentration.
