A method for monitoring a data structure maintained by guest software within a virtual machine is disclosed. The quick-connection elements comprise a washer with teeth disposed in the chamber and associated with a tubular disconnection pusher which is mounted to slide inside the chamber and which possesses a drive end projecting outside the body, and an opposite end for lifting the teeth. The probe alleviates the need to place the main instrument close to an unconfined release of a potentially hazardous material and facilitates analysis of a sample that is situated in a hard-to-reach location while minimizing contamination of the detector and operator.
