Description
Summary:An automated analysis system capable of providing speciation and concentration information for several atmospheric NOx compounds was used to obtain diurnal and location variation data during a five day research cruise in the southeastern Gulf of Mexico between May 18 and May 22, 1987. Speciation of these nitrogen compounds was achieved by selective preconcentration onto a series of chemically coated glass hollow tubes. Analysis was performed by thermally desorbing the collected analytes into a chemiluminescence detector providing sub parts-per-billion level determinations.
