This article reported numerous approaches for encouraging GSs such as ethanol, butanol, esters, polyethylene glycol, supercritical fluids and nonionic surfactants to analyze drugs or compounds. The main aim of this article is to explore the patented GSs for chromatographic analysis and forecasting of the GSs that encourage industries to shift from hazardous to GSs.</p>","PeriodicalId":20011,"journal":{"name":"Pharmaceutical patent analyst","volume":"10 6","pages":"227-235"},"PeriodicalIF":1.3,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39603806","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}
