The invention provides systems and methods for analyzing mixtures and, particularly during processing of the mixtures. The invention provides systems and methods for analyzing mixtures and, particularly, for analyzing mixtures during processing. The methods and systems utilize fluorescence to non-invasively analyze one or more components of the mixture. The analysis may provide a variety of compositional information such as the chemical identity of components, the concentration of components, the uniformity of the mixture and other information. A number of different types of processing equipment can be configured to provide the analysis and, accordingly, the analysis may be performed during a number of processing operations. The system and methods are particularly useful in processing mixtures which are preferably homogeneous blends, such as pharmaceutical products.

Systems and methods for analyzing mixtures using fluorescense

Gas cushions are maintained between a piston and a cylinder of a gas lubricated reciprocating engine which are effective in retarding the approach of the piston to the cylinder wall under the thrust of side forces from the connecting rod. The cushion are maintained by viscous flow forces for sufficient time exceed a half cycle of crankcase rotation.
