An all-glass heated inlet coupled to a homebuilt 5.6 T Fourier transform ion cyclotron resonance mass spectrometer generates stable mass spectra from a volatile mixture for 2 h from as little as 1 μL of injected sample. A dynamic range of ∼500 and ultrahigh mass resolving power, m/Δm50%(approximate)320 000, are shown for a series of test compounds. A raw diesel fuel sample (with hundreds of components over a wide boiling point range) mass spectrum gave ∼500 resolved peaks over a range, 90≤m/z〈300, from which molecular formulas could be assigned from accurate (≤±0.8 ppm) mass measurements. © 1998 American Institute of Physics.
