Green Techniques in Gas Chromatography,eptability analysts are now concentrating to develop green GC, replacing conventional GC. The appreciating feature of green GC is it’s environment-friendliness by the way of reducing/eliminating the amount of solvents required for sample preparation and amount of waste generation or emission of vola

Preparation and Purification of Garlic-Derived Organosulfur Compound Allicin by Green Methodologiesed for preparing and purifying allicin, a garlic-derived organosulfur compound, are described here. A greener version of the acidic oxidation reaction of diallyl disulfide (DADS) is used to produce allicin with high yield. Green RP-HPLC eliminates the liquid/liquid extraction step from either the DA

Studies Regarding the Optimization of the Solvent Consumption in the Determination of Organochlorinodders is extremely important. In case of complex fodders in whose composition there are various materials, the potential contamination sources are multiple. The determination of organochlorine pesticides was made through the gas chromatography method using capillary columns and detector with electr

Size Exclusion Chromatography a Useful Technique For Speciation Analysis of Polydimethylsiloxanes,cules mixtures. This chapter describes the retention mechanisms for SEC as ideal size-exclusion, which separates molecules primarily on the basis of their hydrodynamic volume, and non-ideal size-exclusion, which depends on entropic and enthalpic retention mechanisms and applies when adsorption occur

Preparation and Purification of Garlic-Derived Organosulfur Compound Allicin by Green Methodologiesolvent blend of hexane : isopropanol (92:8) can be used to identify the allicin on TLC plate. Here, the traditional usage of toxic organic solvents has been avoided and a more efficient chemical reaction scheme is employed, which permits the classification of the present method as green. These green
