One embodiment relates to a method of action consolidation so as to avoid duplicative actions. This is accomplished by circulating through the equipment in contact with the polymer an aromatic hydrocarbon solvent having a high boiling point and low vapor pressure for a period of time sufficient to remove the polymer. The alignment mount can comprise a mechanism to adjust the camera relative to the lens to that an image plane of the camera aligns with an image plane of the lens in a predetermined orientation. In some such latter embodiments, the photoacoustic system comprises a light source 201 that passes through a chopper 202 and into a photoacoustic cell 203 comprising the analyte gas. Before the switching of the communication route, the location of the data communication terminal is authenticated by a location register and stored therein. The packaging unit has a container for receiving at least one object and a casing that is able to be slid over the container, the casing covering the container at least partially.
