The single ion Penning trap mass spectrometer at M.I.T. now compares masses with an accuracy of 0.1 part per billion. We have created a table of fundamental atomic masses and made measurements useful for calibrating the X-ray wavelength standard, and determining Avogadro's number, the molar Planck constant, and the fine structure constant.
