Hypochlorite ion chromatography
WebThe oxyhalide anions chlorite, chlorate, bromide, and bromate are separated on a Thermo Scientific™Dionex IonPac AS9-HC column and measured by using suppressed conductivity detection (as in EPA Method 300.1), followed by postcolumn reaction (PCR) to enhance detection of bromate.

WebThe determination of chloride and perchlorate by non-suppressed ion chromatography in aqueous process solutions containing a high sulfate background is described. The method is reliable and fast. The sensitivity for perchlorate is lower than for other anions like nitrate, nitrite and chlorate. WebExample 12.2.2: Pentan-3-one. This time the base peak (the tallest peak - and so the commonest fragment ion) is at m/z = 57. But this is not produced by the same ion as the same m/z value peak in pentane. If you remember, the m/z = 57 peak in pentane was produced by [CH 3 CH 2 CH 2 CH 2] +. If you look at the structure of pentan-3-one, it's ...
