Abstract
An analyte detection apparatus includes a radiation source for irradiating a sample and a receiver to receive an optical Raman spectrum of radiation transmitted back from the sample, the spectrum including one or more parts of significance to an analyte to be detected and one or more parts not of significance to an analyte to be detected. The receiver includes different types of analysis device each arranged to receive a selected part of the spectrum. The different types of analysis device include at least one analysis device having high resolution and/or high signal to noise ratio for detecting a part of the spectrum of significance to the analyte to be detected and at least one second type of analysis device which provides lower resolution and/or lower signal-to-noise ratio, for detecting a part of the spectrum not of significance to the analyte to be detected.
