Top 5 Things You May Not Know About Spectrophotometers

1. In the 1930s, vitamin research indicated that several vitamins, particularly vitamin A, absorb ultraviolet (UV) light. Spurred by the American government’s interest in measuring vitamin content in soldiers’ rations using ultraviolet and visible (UV-Vis) light, this research culminated in the commercial launch of UV-Vis spectrophotometers in the early 1940s.

2. Nobel laureate Bruce Merrifield referred to the UV-Vis spectrophotometer as “probably the most important instrument ever developed toward the advancement of bioscience.”

3. Raman spectrophotometers were once massive benchtop instruments that required a PhD to operate, while today’s instruments are much more portable and easier for non-experts to use.

4. Atomic absorption (AA) has been known since the 19th century, but it was not until the 1950s, thanks to efforts by Alan Walsh at Australia’s CSIRO research center, that use of AA spectrometers became routine for metals analysis.

5. Fourier transform infrared (FTIR) spectroscopy, a subset of infrared (IR) spectroscopy, uses a mathematical algorithm, Fourier transform, to translate raw infrared data into a spectrum.
