NIR spectroscopy is a desirable methodology due to its unique ability to measure a wide
range of different material types such as powders, liquids, solids, and slurries—often with
little or no sample preparation. Users can measure these materials in their current states,
saving analysis time and increasing sample analysis throughput. However, when developing a
method for NIR spectroscopy, care should be taken to ensure that the sample presentation is
both repeatable from user to user and is reproducible over time.
