Mass Spectrometer: How Do We Weigh an Atom? - Science ABC
WebA proton's mass can be measured in a mass spectrometer which accelerates a proton through an electric field where it is deflected by a perpendicular magnetic field. The amount of deflection determines the mass of the charged particle. The more a particle is deflected, the less mass it has. WebHerein, a strategy is proposed for the simultaneous determination of primary coumarins in Peucedani Radix (Chinese name Qianhu). The methodology consists of three consecutive steps: 1) Semi-preparative LC in combination with a home-made automated fraction collection module to fragment the universal metabolome standard into ten fractions (Frs. … ionos email forwarding
