Merging zones asynchronous

Albumin Serum UV-Vis 10-60 g L 1 Merging zones proposal/asynchronous merging zones for signal attenuation [2]... [Pg.251]

An rFIA-asynchronous merging zones configuration has be used for the speciation of up to nine different chromium forms —aquo complex, mono-, di- and tetrahydroxylated Cr(III) and molecular, anionic and dimeric Cr(VI). It Includes a glass-calomel microelectrode Inserted In the sample stream prior to the merging with the reagents, and a microcomputer which acquires the measured pH and chromium concentrations —Cr(VI) and total Cr. These data are pro-cesssed by a computation program In which the equilibrium constants of the... [Pg.499]

Figure 4.67. Manifolds designed for speciation analysis of Cr(VI) and Cr(III) by reversed FI A, both species being determined spectrophotometrically by a single detector, (a) Asynchronous merging zones mode for simultaneous determination of both species, (b) Sequential method for this speciation by use of a selecting valve for determination of Cr(VI) (channel 1) or overall chromium (channel 2).

By a proper selection of pumping rates, the sample and reagent zones might merge synchronously, that is, completely overlapping each other (as shown) or asynchronously, so that a section of a reagent zone does... [Pg.63]
