    摘要: An electrochemical cell is coupled on-line with a mass spectrometer to achieve minimal response time in a system called rapid electrochemical-mass spectrometry (EC/MS). Many large, nonpolar compounds that could not be analyzed by prior ES/MS techniques may now be analyzed. Ionic and polar intermediates and products generated by electrochemical reactions may be probed with very short response times prior to their analysis. Ions are generated by electrochemical oxidation or reduction immediately prior to electrospray release, pneumatic nebulization, or outlet heating. The on-line coupling of an electrochemical cell to electrospray mass spectrometry permits the fast identification of ionic intermediates (both radicals and non-radicals), as well as products generated from electrochemical reactions and from ensuing solution-phase reactions. Neutral compounds that are otherwise difficult to analyze by ordinary electrospray mass spectrometry may now be analyzed. Preferred three-electrode cells are disclosed.

    摘要: Chelating monomers and fluoride-releasing compositions are disclosed that may be incorporated into dental composite restorative materials, dental bonding agents or other dental materials, to produce materials with high fluoride release rates, and high fluoride recharge capability. Such dental restorative materials may help reduce the level of dental caries in patients, particularly the level of caries occurring on the margins of the restorative materials.
