Samples for analysis by FTIR are usually selected and documented under stereo microscopy. Depending on the mode and method of analysis a very small amount of sample material may be sufficient, e.g. a particle of 20µm is plenty - as long as it can be handled with tweezers or a needle under stereo microscopy it is big enough. For FTIR imaging using the germanium ATR crystal a sample may be embedded in resin and polished to reveal a cross-section. Maps of max 500 µm x 500 µm may be collected with a maximum resolution of 5 µm.
