  • Publication number: 20070257202
    Abstract: A system for use in analyzing a pharmaceutical composition having at least one constituent comprising a luminescence sensor having an integral low current light source, the sensor being adapted to direct a plurality of radiation pulses to the pharmaceutical composition and detect luminescence emitted from the composition constituent, the sensor being further adapted to provide at least one luminescence signal corresponding to the detected luminescence, and control means in communication with the sensor for controlling the sensor and analyzing the luminescence signal.

  • Publication number: 20070091308
    Abstract: A system for use in in-situ analysis of pharmaceutical samples, and system comprising means for holding a plurality of said samples, wherein said samples are present in the form of a powder formulation; means for moving said plurality of samples along a sample path; means for generating a plurality of incident radiation pulses of different wavelength; means for illuminating at least a respective one of said samples with at least a respective one of said radiation pulses during said movement of said samples, said radiation pulse having a suitable range of radiation wavelengths capable of inducing a fluorescent response; means for detecting a first resultant fluorescence emitted from each of said samples; first control means in communication with said moving means and said incident radiation generating means for synchronizing said means for illuminating each of said samples with said moving means.

  • Publication number: 20060050765
    Abstract: A remote sensor system (60) and method for passively sensing environmental conditions, such as temperature and humidity, uses a magnetic impulse from an AC interrogation coil (68) to stimulate a magnetoelastic sensor (62) to generate an acoustic signal (AE) at the resonant frequency of the magnetoelastic sensor (62). The acoustic signal (AE) is received by amplifier (74), detected and displayed (76). The systems and methods are particularly suited for detecting environmental conditions in commercial pharmaceutical packaging, such as blister packs.
