Versatile IEEE-488 data acquisition and control routines for a diode array spectrophotometer
The UV-visible diode array spectrophotometer is a work-horse instrument for many laboratories. This article provides simple data acquisition and control routines in Microsoft QuickBasic for a HP-8452A diode array spectrophotometer interfaced to an IBM PC/XT/AT, or compatible, microcomputer. These allow capture of full spectra and measure absorbance at one or several wavelengths at preset time i...
متن کاملAutomated monosegmented flow analyser. Determination of glucose, creatinine and urea.
An automated monosegmented flow analyser containing a sampling valve and a reagent addition module and employing a laboratory-made photodiode array spectrophotometer as detection system is described. The instrument was controlled by a 386SX IBM compatible microcomputer through an IC8255 parallel port that communicates with the interface which controls the sampling valve and reagent addition mod...
متن کاملAnalysis of air injection system for drag reduction in high speed vessels using numerical simulation software ANSYS-Fluid Flow
Many existing phenomena in nature are considered new design ideas in various fields of industry. Bionics is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. By performing bionic review, the researchers found the penguins by delivering air locked under their wings and creating air bubbles, the drag significant...
متن کاملSignal-to-noise optimization and evaluation of a home-made visible diode-array spectrophotometer
This paper describes a simple low-cost multichannel visible spectrophotometer built with an RL512G EGG-Reticon photodiode array. A symmetric Czerny-Turner optical design was employed; instrument control was via a single-board microcomputer based on the 8085 Intel microprocessor. Spectral intensity data are stored in the single-board's RAM and then transferred to an IBM-AT 3865X compatible micro...
متن کاملUsing LSI processor bit - slices to build a PDP - II - A case study in microcomputer design
In this article we give the design and evaluation of the CMU-l1: a fully operational implementation of the PDP-ll computer architecture built with Intel 3000 Schottky bipolar microcomputer bit-slices. This project was initiated to test in detail the claims that LSI processor bit-slices simplify the design of microprogrammed processors. The CMU-II executes approximately 240,000 instructions per ...
