The present invention relates to apparatuses for use in performing a quantitative analysis of a turbid pharmaceutical sample, e.g. a tablet, a capsule or a similar sample forming a pharmaceutical dose. A pharmaceutical, turbid sample () is irradiated with an excitation beam () of radiation, e.g. near infrared radiation. The intensity of emitted radiation () from the sample () is detected as function of both the wavelength of the emitted radiation and the photon propagation time through said sample (). Optionally, the intensity of the emitted radiation () from the sample () is also detected in a spatially resolved manner.

Measuring technique

The present invention relates to a method for analysing the amount of free gas within a pharmaceutical sample. According to the invention the method comprises the following steps: providing a sample before an irradiating source; irradiating the sample with at least one beam of electromagnetic radiation; detecting radiation emitted through the sample and generating signals corresponding to the amount of free gas in the sample, and correlating the generated signals to at least one solid state parameter of the sample.

Method of analysing a pharmaceutical sample

The present invention relates to a method and an apparatus for use in performing a quantitative analysis of a turbid pharmaceutical sample, e.g. a tablet, a capsule or a similar sample forming a pharmaceutical dose. A pharmaceutical, turbid sample ( ) is irradiated with an excitation beam ( ) of radiation, e.g. near infrared radiation. The intensity of emitted radiation ( ) from the sample ( ) is detected as a function of both the wavelength of the emitted radiation and the photon propagation time through said sample ( ). Optionally, the intensity of the emitted radiation ( ) from the sample ( ) is also detected in a spatially resolved manner.
