Microcomputer control and data system for automated multiple flow injection analysis

Microcomputer control and data system for automated multiple flow injection analysis

Introduction Flow injection analysis has been shown to be a versatile technique for the analyses of many types of samples using unsegmented continuously flowing streams. Several recent reviews have discussed a variety of aspects of this field 1-5]. The automated version of flow injection analysis (usually called automated multiple flow injection analysis or AMFIA) is attractive for those labora...

Automated titrations: the use of automated multiple flow injection analysis for the titration of discrete samples

Introduction In 1974 Fleet and Ho 1] successfully demonstrated an automated continuous flow titration system using a reagent gradient. This system had a throughput of only ten samples per hour, but it was significant since it demonstrated the principles for titration of discrete samples in continuously flowing streams. Nagy et al. [2,3 ]have also demonstrated a similar approach. In 1977, Ruzick...

Analysis of Transient Flow in the Case of Secondary Injection for Transient Vector Control (RESEARCH NOTE)

The purpose of this paper is to analyze the flow field structure in transient state and performance of secondary injection system for thrust vectoring in divergent section of a two-dimensional nozzle. Secondary injection for thrust vectoring in a two-dimensional nozzle is studied by solving three-dimensional Reynolds-averaged equations by means of fluent solver. Spalart-allmaras model was used ...

A microcomputer program for automated neuronal spike detection and analysis.

A system for on-line spike detection and analysis based on an IBM PC/AT compatible computer, written in TURBO PASCAL 6.0 and using commercially available analog-to-digital hardware is described here. Spikes are detected by an adaptive threshold which varies as a function of signal mean and its variability. Since the threshold value is determined automatically by the signal-to-noise ratio analys...
