A mass spectrometer is disclosed comprising a sampling cone (3) and a cone-gas cone (4) wherein, in use, sulphur hexa fluoride ('SF6') is supplied as a cone gas (5) to the annulus between the cone-gas cone (4) and the sampling cone (3) in order to improve the transmission of high molecular mass ions passing through the sampling cone (3) into and through subsequent stages of the mass spectrometer.
La présente invention concerne un spectromètre de masse comprenant un cône d'échantillonnage (3) et un cône de cône à gaz (4) où, lors de l'utilisation, l'hexafluorure de soufre ('SF6') est fourni tel qu'un cône à gaz (5) à l'espace annulaire entre le cône de cône à gaz (4) et le cône d'échantillonnage (3) afin d'améliorer la transmission d'ions de masse moléculaire élevée passant à travers le cône d'échantillonnage (3) dans et à travers des étapes successives du spectromètre de masse.
