Flow Manifold For Automated On-Line Dilution Of Standards For Flame Atomic Absorption Spectrometry And Its Use In A Null Measurement Method, S. R. Bysouth, Julian Tyson Jan 1987

Flow Manifold For Automated On-Line Dilution Of Standards For Flame Atomic Absorption Spectrometry And Its Use In A Null Measurement Method, S. R. Bysouth, Julian Tyson

Chemistry Department Faculty Publication Series

A flow manifold that automatically dilutes solutions presented to a flame atomic absorption spectrometer while maintaining a constant flow to the nebuliser is described. The manifold is based on a fixed-speed pump, together with a computer-controlled stream switching valve and pump. The computer is also used for data acquisition and handling. In addition to the production of solutions for a conventional calibration procedure, the system is also used for a novel calibration procedure whereby the stock standard solution is automatically diluted by a known factor until its absorbance matches that of the sample. This null measurement method avoids the need …

Analytical Information From Doublet Peaks In Flow Injection Analysis Part Ii. Determination Of Stability Constants, Julian Tyson Jan 1987

Analytical Information From Doublet Peaks In Flow Injection Analysis Part Ii. Determination Of Stability Constants, Julian Tyson

Chemistry Department Faculty Publication Series

An equation was derived for the determination of a stability constant from a flow injection titration experiment in which the product of the reaction is monitored. This equation showed that if the product concentration at the equivalence points of the titration was used as the basis for the calculation, the method was independent of all the variables associated with the flow injection system, provided that a single-line manifold was used. If the system corresponded to that described by the well stirred mixing chamber model, then the time interval between the peaks could be used to determine the ratio of the …


Models For Dispersion In Flow Injection Analysis Part 1. Basic Requirements And Study Of Factors Affecting Dispersion, David C. Stone, Julian Tyson Jan 1987

Models For Dispersion In Flow Injection Analysis Part 1. Basic Requirements And Study Of Factors Affecting Dispersion, David C. Stone, Julian Tyson

Chemistry Department Faculty Publication Series

The various approaches adopted for accounting for dispersion behaviour in flow injection analysis are examined and the advantages of a modelling approach are discussed. The variation of the dispersion coefficient as a function of (a) flow-rate, (b) tube length, (c) tube inner diameter and (d) method of injection obtained under typical flow injection conditions are studied and discussed. Explanations for some of the effects observed are presented in terms of molecular diffusion and convective flow patterns. The advantages of "time" injection over the more usual "slug" injection are clearly demonstrated and the use of the single well stirred tank model …
