The momentum J is J * mv * e Br the result is: and 2 * 2e Vm = m a (si) m As, in this analysis, an ion of mass m has to pass the magnetic as well as the electric sector, hence from equations XI and XII: And: Ε m r„ D 2 2 e r M The ratio of the field strengths in the analyser of the mass spectrometer for the passage of an ion of mass m can therefore be calculated as follows: - m . Κ (XIII) 40 Hardware As the radii of the sector r^ and r respectively, as well as the charge e are constants, it can be derived from equation XIII that ions of mass m, yet with different kinetic energy and momentum, can pass the analyser of a double focusing mass spectrometer if the quotient B^/E is adjusted accordingly.

For the sake of comparison several of these compounds were synthesized and tested by conventional mass spectrometry (30). One example, 3,17-dihydroxy-5androstane-11, 16-dione is representative of this type of compound. In its conventional mass spectrum (Fig.
