"Impulse/response Functions Of Individual Components Of Flow Injection Manifolds"
Anal. Chim. Acta 1988 Volume 214, Issue 1-2 Pages 77-86
I. C. van Nugteren-Osinga, M. Bos and W. E. van der Linden

Abstract: Mathematical deconvolution is applied to evaluate the impulse/response functions of the individual parts of a flow injection manifold system. A fast Fourier transform algorithm was used. The results enable prediction of performance of other modular arrangements of such parts.

"Use Of The Hunt Filter To Optimize The Determination Of Impulse Response Functions Of Individual Component Parts Of Flow Injection Manifolds"
Anal. Chim. Acta 1989 Volume 222, Issue 1 Pages 151-157
I. C. Van Nugteren-Osinga, M. Bos and W. E. Van der Linden

Abstract: The dispersion behavior of the various individual parts making up a flow-injection manifold can be expressed by means of impulse-response functions. These functions can be determined by deconvolution of the response curves obtained with and without the part concerned. Special attention is paid to a procedure to decrease the influence of noise. It is shown that good results can be obtained with a Hunt filter which operates in the Fourier domain.

"Flow Injection Analysis - A Survey Of Its Potential As Solution Handling And Data Gathering Technique In Chemical Research And Industry"
Fresenius J. Anal. Chem. 1988 Volume 329, Issue 6 Pages 653-655
Jaromir Ruzicka

Abstract: The possible applications of flow injection analysis are reviewed briefly, with examples described diagrammatically. Uses considered are, as a tool for serial assay, continuous monitoring and process control, miniaturization and integration, as a link between chemical and instrumental methods, to enhance detector performance and as an impulse response technique.

"Aspects Of Signal-processing In Flow Injection Systems: Review"
South Afr. J. Chem. 1995 Volume 48, Issue 1-2 Pages 8-14
Van Staden, J.F.

Abstract: Much valuable information is contained in the output signal of a detection system in flow injection analysis. The form of the peak obtained and deviations therefrom are functions of the type of detector and manifold used. The shape and quality of the analytical signal obtained may have a major influence on the performance of a flow injection analyzer.. There are a number of factors to consider in the accumulation and processing of such signals. Among these are noise, signal-to-noise ratio and signal transport. A number of signal-processing techniques for the filtering of noise are described in this review. Multianalyte information from a single sample injection is addressed using a multivariate calibration technique. Response surface mapping has proved to be a useful way of visualizing the effect of multivariable optimization. (64 References)
