The sensitivity of the detector in this case amounts to 96500 C/mol. A hypercoulometric response is given, if fragments from dissociative processes undergo electron capture at several times and if the enhancing effect of space charges is used. In this case the sensitivity of the ECD exceeds the upper limit given by Faraday's number. The operation conditions of both EGD-modes are described.","PeriodicalId":430185,"journal":{"name":"Mai 1983","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128798233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extensive studies of infrared absorption spectra and analysis of the X-ray diffraction patterns were carefully conducted before and after exposure to high energy gamma absorbed dose (5 × 108 rd). Results obtained indicated that acetylcholine bromide has higher radiation resistance than acetylcholine iodide and this was discussed on the basis of bond strength and electronegativity differences. These could be also discussed in terms of gamma absorbed dose damage and their attendent creation of lattice imperfections in combination with donor defect centres which are liable to occur pronouncedly for the iodide salt. Finally, the IR absorption spectra as well as X-ray diffraction analysis could find their great usefull application as a rapid and sensitive tools for radiation detection at high efficiency using acetylcholine halides po...","PeriodicalId":430185,"journal":{"name":"Mai 1983","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114634871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
