PERFLUOROALKYL-S-TRIAZINES AS MASS CALIBRATION STANDARDS FOR TIME-OF-FLIGHT SPECTROMETRY

In order to determine the mass of an ion produced in a mass spectrometer, it is often necessary to introduce along with the sample a calibration standard which gives reference ions of known mass. Both the method of calculation and the choice of standard depend upon the nature of the spectrometer used. Although this variability in requirements has been observed by mass spectrometrists possessing the necessarily varied experience, and although valuable bits of information are exchanged at users' conferences and transmitted somewhat haphazardly through the medium of the manufacturers' service engineers, the inadequacy of published information is still an unnecessary handicap to the operator who sets out in the traditional industrial fashion to teach himself the use of the instrument. © 1969, American Chemical Society.
