1. An analyte detection apparatus, comprising:
a radiation source for irradiating a sample, and
a receiver, to receive an optical Raman spectrum of radiation transmitted back from the sample in response to the received radiation from the radiation source, the optical Raman 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,
wherein the receiver comprises a plurality of different types of analysis device each arranged to receive a selected part of the received Raman optical spectrum transmitted back from the sample
wherein the different types of analysis device include at least one analysis device which has resolution and/or 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.
