Happy Birthday, Periodic Table!

The Periodic Table of the Elements is 150 years old this week!

On March 6, 1869, chemist Dmitri Mendeleev made a presentation to the Russian Chemical Society.  For the first time, he organized elements into chemical families based on their atomic weight and valence (ability to bond with other elements).

(Coincidentally, German chemist Julius Lothar Meyer independently published an almost identical table just a few months later.)

Mendeleev’s table was also remarkable because he accurately predicted the qualities of elements that had not yet been discovered, including gallium, germanium and scandium.

There were 60 elements in Mendeleev’s original table.  Today, more than 110 elements are known to science.

Agilent has been a world leader in chemical analysis for more than 50 years.  We invented fused-silica capillary columns, which catapulted gas chromatography into mainstream laboratories.  Our 5890 GC remains the best-selling gas chromatography instrument of all time.  And currently, our Agilent Intuvo 9000 GC System and Agilent Ultivo Triple Quadrupole LC/MS instruments have revolutionized gas chromatography, liquid chromatography and mass spectrometry.

And Agilent has a robust Atomic Spectroscopy portfolio for quantitating the elements in the periodic table.  From our atomic absorption and microwave plasma… to our ICP-OES and ICP-MS instruments… we enable measurements from percentages down to parts-per-quintillion.

In 2012, we introduced our ICP-QQQ with MS/MS capabilities and revolutionized the atomic market.  Our current second-generation 8900 ICP-QQQ demonstrates that Agilent is still at the cutting edge of innovation.

Thanks to Agilent’s Victoria Wadsworth-Hansen for suggesting today’s blog topic.  Thanks to Agilent’s Amir Liba, Ph.D., for his help with the atomic spectroscopy portfolio.
