Different types of plasmas with their special characteristics for various applications are described. Indirect analytical methods involving sample digestion and often also analyte/matrix separation prior to analyzing the samples still represent the most important routine methods. Here, plasma optical emission and mass spectrometry are the most frequently used determination techniques with a wide variety of instruments commercially available. To avoid the risk of analyte loss or of contaminations during an often time consuming and laborious sample preparation, the use of techniques with direct solid sampling is considered an attractive alternative for the analysis of many materials. A survey on applications with a special focus on direct solid sampling techniques such as GDMS, GD-OES, LA-ICPMS, ETV-ICPMS, ETV-ICP-OES, DC-Arc is given. Different possible calibration strategies are discussed.","PeriodicalId":119970,"journal":{"name":"Encyclopedia of Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115080931","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}

They can be found in different parts of plants usually as multicomponent mixtures. They are composed of the triterpene or steroidal aglycone to which a number of sugars in the form of one, two, or three sugar chains are attached. Depending on the chemical structure, they show different biological activities. The common feature of these compounds is surface activity, so they can be used as emulsifiers, and in the past, they were used as soap substitutes. Some of them have found application in food industry, whereas the others are being considered as antinutritional substances. Owing to the fact that saponins occur in quite complex mixtures, their separation to individual compounds is still a challenge. Also, their determination with chromatographic techniques creates some problems as they are lacking chromophores allowing ultraviolet (UV) detection. Precolumn derivatization, light scattering detection, and liquid chromatography coupled with mass detector are the methods of choice for their determination. \u0000 \u0000 \u0000Keywords: \u0000 \u0000saponins; \u0000glycosides; \u0000steroids; \u0000triterpenes; \u0000analytical methods","PeriodicalId":119970,"journal":{"name":"Encyclopedia of Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126243487","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}

NP presence can be identified by electron microscopy (EM) but this is a time- and labor-consuming technique. So, instead of determining the presence of the NPs themselves, distribution studies can use elemental analysis by inductively coupled plasma mass spectrometry (ICPMS) as indication for the tissue distribution of NPs. In the field of analytical research, the suitable application of ICPMS is crucial and discussed in detail. Other relevant analytical techniques, the obtained results as well as the evaluations, are presented too.","PeriodicalId":119970,"journal":{"name":"Encyclopedia of Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121511841","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}
