Summary:A method of liquid characterisation using an optical characterisation system. The optical characterisation system comprises an optical element comprising a light source and light detector, and defining a light path extending between the light source and light detector. The detector resolves light intensities at varying wavelengths. The system also comprises a liquid container and a photonic crystal attached to the first container surface and facing the interior. The method comprises: recording a first transmission spectrum, wherein at least part of the first and second container surfaces, the interior containing liquid and the photonic crystal intercept the light path, and the interior intercepts the light path before the photonic crystal, and recording a second transmission spectrum. At least part of the first and second container surfaces, the interior containing liquid and the photonic crystal intercept the light path. The photonic crystal intercepts the light path before the interior.
