    Gasporox system GPX Porosity for measuring porosity in pharmaceutical substrates

    videosGasporox AB
    September 7th 2023

    The GPX Porosity is a completely non-destructive and non-contact at-line instrument for optical porosity analysis of ribbons produced by e.g. a roller compactor in the process of the tablet production. The instrument is fast with a measurement time of a few seconds, accurate and easy to use.

    No special sample preparation is required. The sample is placed on the sample stage and the automated process of the instrument moves the sample into the instrument, which offers easy testing. No lab with additional instruments needs to be available and the measurement can be done at-line by a normal line operator. Due to the non-destructive technique, the sample is unchanged after measurement and is available for further use. The instrument is operated by the proprietary software GPX Porosity-studio.

    Technology: Gasporox is highly specialize in the development and application of optical spectroscopy. The system combines two techniques, GASMAS (GAs in Scattering Media Absorption Spectroscopy) and TOF (Time Of Flight). A special algorithm is calculating the optical porosity and the integrated calibration curve converts it to the physical porosity.
