Abstract: A unit is provided comprising an array (2) of sample containers (1), said containers, being connected together and arranged in a planar configuration, each container having multiple optically transparent windows arranged such that the sample contained therein can be interrogated using simultaneous multiple optical analytical techniques, the array of containers being configured so as to allow optical access to the windows of each container in the array. Also provided is an apparatus comprising such a unit, a system comprising a combination of such an apparatus and unit and a method of analyzing multiple samples by introducing each individual sample into an individual container of such an apparatus, illuminating the samples and detecting and analyzing light emerging therefrom.

Abstract: An apparatus for delivering a plurality of liquid volumes sequentially to a reaction site is provided, the apparatus comprising a vessel having a plurality of solid spacers arranged in linear order therein so as to define a series of adjacent voids, separated by individual solid spacers, for receiving said liquid volumes, the vessel being provided in a lateral wall with a plurality of reversibly sealable openings through which the liquid volumes for delivery to the reaction site may be introduced into the voids defined therein, and an outlet port, the spacers being movable within the vessel such that, in use, liquid volumes disposed in the individual voids are deliverable sequentially through the ‘outlet port to the reaction site. Also provided are units, such as disposable cartridge units, comprising such an apparatus coupled to a reaction site and systems comprising such units together with means for interrogating the reaction site to determine the outcome of the reaction.

Abstract: Raman band detection apparatus illuminates a sample using an illumination source that oscillates in wavelength over a range. The source might for example switch between two wavelengths or might traverse the wavelength range. A wavelength sensitive detector detects radiation emitted by the sample at a series of different wavelengths and a signal processor extracts signals that have a temporal correspondence to the wavelength variation of the illumination at the different wavelengths. One or more Raman bands that might be present will produce a distinctive characteristic of the extracted signals plotted against a spectral axis and relatively simple processing of these spectrally-related time-varying components can then enhance the appearance of the Raman band in a spectral representation based on the processed components.
