The problem of acceptable accuracy in mass calibration for fast‐atom bombardment (FAB) mass spectrometry has recently received some attention (K. Véekey, Rapid Commun. Mass Spectrom. , 2, 213 (1988); Idem., Org. Mass Spectrom. , 24, 183 (1989). We describe here a calibration method for negative‐ionFAB, using gold cluster ions, which provides facile mass calibration over the range from can 200 u to 10000 u . Under suitable conditions, it is possible to use these ions as internal standards for accurate mass measurement.
