Advantages of rapid methods based on spectroscopy

NIR spectroscopy is characterised by low molar absorptivities and scattering, which permit nearly effortless evaluation of pure materials. The NIR region of the electromagnetic spectrum, once regarded as having little potential for analytical work, has now become one of the most promising for molecular spectroscopy. The advent of inexpensive and powerful computers has contributed to the surge of NIR spectrophotometric applications. NIR spectroscopy conserves time and materials in comparison to many more conventional analytical methods because:

1. analysis times under 1 second are possible
2. simultaneous multicomponent analysis is the norm
3. no sample preparation is usually required for liquids, solids, or gases
4. non-invasive and non-destructive analysis is possible
5. cost per analysis is very low (no reagents are used)
6. physical properties and biological effects can be calculated from spectra of samples
7. automated correction of background and interferences can be performed in instruments using a computer algorithm
8. detection limits can be low
9. samples sizes ranging "from picograms to planets" can be analysed
10. molecular structural information can be derived from spectra
