A method of spectrometric analysis comprises obtaining one or more sample spectra for an aerosol, smoke or vapour sample. The one or more sample spectra are subjected to pre-processing and then multivariate and/or library based analysis so as to classify the aerosol, smoke or vapour sample. The results of the analysis are used for various surgical or non-surgical applications.

A droplet collection unit of an embodiment includes a generator and processing circuitry. The generator produces droplets each containing a microorganism and a substrate that reacts with an enzyme derived from the microorganism. The processing circuitry detects a reaction between the enzyme and the substrate in each droplet. The processing circuitry sorts the droplets on the basis of a detection result of the reaction.
