Civanar amirtam is a siddha herbo- mineral formulation prescribed for rheumatism, bronchial asthma, tuber culosis and leprosy. Of the nine ingredients which constitute the preparation, four are inorganic and the others are plant drugs, Attempts have been made to chemically analyse and to identify the presence of each ingredient in the medicine to lay down standards. The identification of variou...

Silver nanoparticles (NPs) have been the subjects of researchers because of their unique properties (e.g., size and shape depending optical, antimicrobial, and electrical properties). A variety of preparation techniques have been reported for the synthesis of silver NPs; notable examples include, laser ablation, gamma irradiation, electron irradiation, chemical reduction, photochemical methods,...

Asbestos fibers, members of complex crystal-chemical systems, possess some range in characteristic properties. Identification of fibers requires morphological, structural, and chemical data. Most current work centers on identification of single, sublight-microscopic fibers present as contaminants in a range of media. Constraints encountered in the analysis of such materials are: sample preparat...

Nowadays, a lot of time and resources are used to determine the quality of goods and services. As a consequence, the quality of measurements themselves, e.g., the metrological traceability of the measured quantity values is essential to allow a proper evaluation of the results with regard to specifications and regulatory limits. This requires knowledge of the measurement uncertainties of all qu...

Herein we propose a novel approach to the preparation of quasi-1D nanostructures with various chemical compositions based on infiltration of colloidal solution into the asymmetric anodic alumina membrane. The proposed technique was successfully applied for the preparation of ordered arrays of the magnetically hard anisotropic hexaferrite nanostructures.

A method of preparation and a preliminary chemical investigation of the substance present in commercial (pig) pepsin which reacts with human A antiserum are presented. The material offers especial advantage in securing in quantity a serologically highly active preparation suitable for further studies. Active preparations were isolated moreover from commercial (pig) gastric mucin. Some other mat...

A method is described for the purification of the A substance in horse saliva, and additional observations on the chemical properties of the preparation are reported. The preparation isolated was found to be highly active serologically and it appears to be polysaccharide in nature.

Description: Integrating SAMPLE PREPARATION conference webcast, a part of the Knowledge Foundation’s Detection Technologies Conference Series an internationally recognized meeting for experts in sample preparation technologies for detection, identification and analysis of biological and chemical agents and threats, will explore the latest R&D developments as well as ready-to-market technologies...
