An electrosurgical system includes an evacuator apparatus and a sensor. The evacuator apparatus evacuates aerosol and smoke generated during application of electrosurgical energy. The sensor is operatively coupled to the evacuator apparatus and senses the aerosol and smoke generated during application of the electrosurgical energy. The sensor generates data in response to the sensed aerosol and smoke. The sensor operatively communicates the data to the evacuator apparatus and the evacuator apparatus evacuates the aerosol and smoke as a function of the data.

A system and a method for determining the leakproofness of an object having a first cavity. The system includes a closed chamber having a second cavity arranged to envelope the object, an evacuator for lowering the pressure inside one of the cavities, a supply for supplying a tracer gas into the one of the cavities rendered the higher pressure, a detector sensitive to the tracer gas and an introducer for introducing a transport gas into the one of the cavities rendered the lower pressure. Furthermore, the evacuator is arranged to compress arriving gas to the ambient pressure of the chamber and to communicate with the detecting means, which is suited for operation at the ambient pressure of the chamber. The tracer gas is hydrogen.

A method for lubricating a metal workpiece during a metalworking process includes delivering supercritical carbon dioxide to the workpiece during the metalworking process. The supercritical carbon dioxide acts as a lubricant, coolant, chip evacuator, and/or carrier for another lubricant or corrosion inhibitor.
