✦ Synopsis

Many reagents cannot easily be applied in quantitative analysis, because of their instability under atmospheric conditions. When such reagents are prepared in a flowing stream, their applicability is very promising; for example, in flow injection analysis, a reagent need be stable only for 20-30 s. The application of chromium(I1) and vanadium-(II) in flow injection analysis is described. Nitrate and nitrite can be determined in the concentration range 5 x 1 O-5-5 x 10". Calibration graphs show good linearity.
