ABSTRACT:
Apparatus for selectively and precisely placing a chemical analysis probe (such as a fiber optic probe): (1) in a liquid sample contained in an open-mouthed sample vessel positioned on a sample support, or (2) in a wash collection chamber. Any residual sample remaining on the probe can be washed from it with a stream of volatile wash liquid when the probe is in the wash collection chamber and jets of gas can be directed onto the washed probe to speed the evaporation of any residual wash liquid from the probe. A latch can be used to hold the probe in the wash collection chamber. In one embodiment, four parallel two-ended link members are used, each of which are pivotally attached at one end thereof to a stationary portion of the station and each of which are pivotally attached at the other end thereof to a movable portion of the station, the probe being attached to the movable portion of the station so that the probe can be moved along a predetermined path from a position within the collection chamber to a precise position of immersion in the sample and at a later time back to a position within the collection chamber.
