This slide presentation begins by outlining background information on how organic N-chloramines are produced, why they are of concern, and existing analytical methods. Size Exclusion Chromatography is selected as the method to quantify total organic N-chloramines directly. A summary of conclusions indicates: the developed method allows us to analyze total organic and inorganic chloramines separately; equal signals were achieved for all tested organic chloramines; any of tested peptides or glycine could be used as a standard compound for the quantification of total organic chloramines; no evidence of decomposition or consumption of Organic N-chloramines during elution is observed; and, the SEC-ED method fills the analytical gap which existed between measuring total residual chlorine and individual chloramines by allowing the analysis of total organic and inorganic chloramines. Includes figures.
