Health Inequity in the Philippines derivatization were examined using GC/MSD/FTIR Hewlett Packard system. Diazomethane methylation and BSTFA silylation were used to obtain derivatives convenient to GC process. Van den Doole retention indices against M-series, EI and ammonia CI MS spectra as well as FTIR spectra were obtained and discussed in the paper.

https://doi.org/10.1007/978-981-13-6268-2and N,N-diisopropylamino- substituted thiophosphonic esters and acids as well as phosphonic anhydrides were identified. Diazomethane methylation was used to obtain derivatives convenient to GC process. Retention parameters and EI-MS spectra were obtained and presented in the paper.

Drug Toxicity and Hormonal Dysfunction derivatives. Polar, ionic, involatile, high molecular weight and thermally labile analytes are readily chromatographed by HPLC which is also often used to separate analytes amenble to GC, simply because sample extraction and clean up can be more straightforward prior to LC, or because the method is quicker, more specific or more convenient.

Emergency and integrated management programsem on a routine basis for many years and have built up considerable expertise and experience in this area. This paper addresses the problems associated with the recovery, identification and safe disposal of these old chemical munitions and highlights the experience gained by some European countries in dealing with the problem.
