WebDescription The EAS CARBSORBER is a ready for use CO2 absorber for the application in elemental analysis. The material can be directly used as delivered and serves as a substitute for sodium hydroxide on carrier or a mixture of sodium hydroxide on carrier and quartz chips. The filling level corresponds to the former NaOH. Electrophilic fluorination is the combination of a carbon-centered nucleophile with an electrophilic source of fluorine to afford organofluorine compounds. Although elemental fluorine and reagents incorporating an oxygen-fluorine bond can be used for this purpose, they have largely been replaced by reagents containing a nitrogen-fluorine bond. Electrophilic fluorination offers an alternative to nucleophilic fluorination methods employing alk… dark red opi colors
