A SIMPLE METHOD FOR QUANTIFYING TRIAZINE HERBICIDES USING THIN-LAYER CHROMATOGRAPHY AND A CCD CAMERA

A Simple Apparatus for Thin-layer Chromatography.

Thin-layer chromatography was introduced by Stahl (1956) and has advantages over paper chromatography in speed, resolution, and smaller sample size. Also, the physical nature of the thin layer allows its treatment, where necessary, with strong acids and alkalis. It has been found possible to construct a satisfactory, cheap, and simple apparatus for the preparation of thin layers on glass carrie...

A Proposed Simple Teleradiology System Using a Digital Camera

Background & Aims: Teleradiology as an efficient way for avoiding unnecessary transfer of patients to special medical centers requires the images with digital format. However, in some developing countries, including Iran, imaging is being done using non digital devices. In such cases, changing analog images into digital ones can solve the problem. The method which is nowadays used for digita...

A Simple Method for the Separation of Minute Amounts of Tissue Lipids by Thin-layer Chromatography and Gas-liquid Chromatography.

A simple method for recording thin-layer acrylamide gel electropherograms.

Thin-layer acrylamide gel electrophoretic technique, based on the method described by Nandi and Lewis,' has been used in our laboratory for the electrophoresis of blood and malaria parasite enzymes. It was found that preservation of the enzyme electropherograms in acid solution is cumbersome, space-occupying, and unstable. Alternative methods for permanent recording of the electropherograms are...
