ABSTRACT:
A sample inlet apparatus comprises a sample source (1) and a first enclosure (3), connected to the sample source via a first inlet (2). An analyser enclosure (7) is connected to the first enclosure (3) via a second inlet (5,15) substantially in alignment with the first inlet (2). Also provided is a second enclosure (10), connected to the analyser enclosure (7) via a third inlet (9) substantially in alignment with the first (2) and second (5,15) inlet, and vacuum pumps (4,11) for maintaining the first (3) and second enclosures (10) at a pressure lower than the sample source (1) and higher than that of the analyser enclosure (7) in use, whereby a molecular beam of sample molecules is generated along the axis of the inlet.
