50 Years of Laser Diffraction The Quest for the Oldest

And the Winner Is ...

MITSUBISHI STEEL JAPAN with a MICROTRAC 9210 SRA laser diffraction analyzer, installed in January 1993!

We are delighted to announce that MITSUBISHI STEEL, represented by Mr. NORIKAZU WATANABE and Mr. TOSHIHIRO SUZUKI (Quality Assurance Office), is the overall winner of our QUEST FOR THE OLDEST competition.

Our instrument is still at the heart of the action – even after three decades!

For 30 years, MITSUBISHI STEEL has relied on the 9210SRA diffraction laser instrument to ensure that every product meets rigorous pre-shipment quality standards. Mr. SUZUKI underlined the importance of this instrument in his daily work:

"Without this inspection, it would be impossible to ship the products".

Maintenance has been limited to cleaning and replacing the cell glass. This is proof that Microtrac designs solid, durable tools ready to take on any challenge. It is through instruments like these that users can achieve exceptional results and continue their innovations without compromise.

50 Years of Laser Diffraction The Grand Prize

Our lucky winner is awarded a new SYNC, the cutting edge of our innovation in particle analysis. Microtrac's SYNC analyzer revolutionizes particle characterization by combining high-precision laser diffraction and dynamic image analysis, for simultaneous, integrated measurement on a single sample. Designed for quality control and research, it offers a detailed analysis of particle size and morphology over an extended range from 0.01 to 4000 microns. Thanks to its powerful software and BLEND routine, SYNC is an essential tool for advanced particle characterization.

Many thanks to all the participants!

This competition was an opportunity to rediscover the history of Microtrac instruments through time and worldwide! We would like to extend our warmest thanks to everyone who took part in The Quest for the Oldest. This contest has allowed us to unveil fascinating stories, and to better understand how our instruments continue to be used and appreciated over the years. Each story reminds us of the value of precision and reliability in our work, and we are honored that our instruments are a key element in the success of our users.
