Abstract

The present invention relates to a method and 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 (57) is irradiated with an excitation beam (53) of radiation, e.g. near infrared radiation. The intensity of emitted radiation from the sample (57) is detected as function of both the wavelength of the emitted radiation and the photon propagation time through said sample (57). Optionally, the intensity of the emitted radiation from the sample (57) is also detected in a spatially resolved manner. Preferably, the sample (57) is alnalysed with a Fourier transform spectrometer (54, 55, 56) comprising a moving a moving mirror (55) and producing an interferogram. The scanning speed of said moving mirror (55) is slower than the light source (52) modulation frequency. A phase comparator (61) compares signals from the modulation driver (50) and from the detector.
