    Abstract: There are disclosed pressurised aerosol compositions comprising a medicament, a hydrofluorocarbon propellant and a polyethoxylated surfactant, the compositions containing substantially no solvent, other than the propellant, capable of increasing the solubility of the surfactant in the propellant. The compositions according to the invention are advantageous in that the solubility of the surfactant is such as to ensure good dispersion of the medicament and smooth operation of the aerosol valve.

    Abstract: A quadrupole mass filter (1) includes a controllable RF oscillator (7) which follows any drift in the resonant frequency of a resonant circuit means (8), this circuit means (8) amplifying an alternating RF potential from the oscillator (7) and supplying it to the filter electrodes (2, 3, 4, 5). To ensure that the charge to mass ratio of the particles transmitted by the filter remains constant, a signal for controlling the amplitude of the oscillator (7) is corrected in response to any resonant frequency shift. This signal is also fed to DC supply means (12, 13, 15), to ensure that the amplitude of the DC potential applied to the electrodes (2, 3, 4, 5) remains in the correct ratio to the RF potential amplitude so that the filter resolution remains constant.

    Abstract: The invention provides methods and apparatus for atomic emission spectroscopy and for mass spectrometry which make use of an inductively coupled radio-frequency plasma torch. A radio-frequency power supply supplies energy to a plasma induction coil via reflectometer means and a matching network. A signal indicative of reflected power generated by the reflectometer is used to set the frequency of the power supply to the resonant frequency of the matching network and plasma induction coil, thereby ensuring the maximum efficiency of power transfer irrespective of the state of the plasma. Preferably a solid state power amplifier is employed in conjunction with a lower power variable frequency oscillator. Means for ensuring proper ignition of the plasma while maintaining the frequency of the power generator within a governmentally specified frequency band are also provided.
