    Abstract: The invention relates to a measurement apparatus for measuring the concentration of a gaseous substance. The apparatus comprises a light source, a light sensor, and a housing comprising at least one first housing member having a low thermal conductivity. A light path is formed from said light source to said light sensor, wherein the light path passes through a measurement region within said housing. The light source is configured to emit light with a spectral distribution such that said light is absorbed by said gaseous substance. Said light sensor is configured to receive the light emitted by the light source after it has passed through the measurement region. The first housing member comprises a thermal shielding region facing said measurement region on its one side and said light sensor on its other side, and is configured to permit the passage of light.

    Abstract: Aspects relate to on-line compensation of instrumental drifts in miniaturized spectrometers due to variations in environmental conditions and due to other sources of instrumental drift. The spectrometer may include a light modulator, a detector, and a processor. The spectrometer may further include a sensor configured to obtain a value of a condition contributing to instrumental drifts in the spectrometer. The processor may be configured to extract a set of correction parameters from a correction matrix associating a plurality of sets of correction parameters with sensor values based on the value and to apply the set of correction parameters to an output of the detector to produce a corrected spectrum of a sample under test. The correction matrix may be generated for the spectrometer or may be based on a global correction matrix fitted to the spectrometer.

    Abstract: An instrument determines a concentration of bacteria in a plurality of fluid samples, and comprises a housing, a rotatable platform, a plurality of fluid containers, a light source, a sensor, and a motor. The rotatable platform is within the housing. The fluid containers are located on the rotatable platform. Each fluid container holds a corresponding one of the plurality of fluid samples, and has an input window and an output window. The light source provides an input beam for transmission into the input windows of the fluid containers and through the corresponding fluid samples. The input beam creates a forward-scatter signal associated with the concentration of bacteria. The motor rotates the rotatable platform so that the input beam sequentially passes through each fluid sample. A sensor within the housing detects the forward-scatter signal exiting from the output window associated with the fluid sample receiving the input beam.
