A computer-controlled potentiometric/spectrophotometric titrator

A computer-controlled potentiometric/spectrophotometric titrator

A laboratory computer controlled potentiometric titrator interfaced to a diode array spectrophotometer is described. The titrator consists of widely used, commercially available components; therefore, major attention is given to modes of interconnection and software implementation in data format and system control. Replicate potentiometric titrations of glycines gave a relative standard deviati...

Comparing live lecture, internet-based & computer-based in-struction: A randomized controlled trial

  Background :Comparing computer and internet based instruction with traditional giving lecture would provide enough evidence to identify best teaching practice. In this study, we compared lecture, interactive internet based and computer based learning regarding medical students' knowledge acquisition and satisfaction in teaching pathophysiology of hematology and oncology.   Methods : Eighty fo...

A PC-based titrator for flow gradient titrations

This paper describes a PC (personal computer) based titrator which was developed for gradient flow titrations. Concentration gradients were generated electrolytically or volumetrically in small tubes. Complete titration curves can be recorded on-line and evaluated automatically. The titrator can be used with all liquid flow detectors with low axial dispersion. The titrator was evaluated for the...

Computer - Controlled Smell Output

Computer-controlled scent output technologies have a history dating back nearly 50 years. However, it’s only in the last few years that such systems have become easy to use and readily available, fueled by the emphasis on multimedia technologies from the internet and dot.com boom and by the increasing prominence of fragrance in everyday life. The key advantage of computer-controlled output, in ...
