Hi Curt - nope, but everyone is on the right track looking at the Rare Earth elements. The Friday Quiz will close at 3:00 PM CST so there is still time to sleuth. The key clue is the link of who first used ion-exchange chromatograph to produce a pure sample of the element in the quiz.

This may be a first for the Friday Quiz - no correct element answers? Looks like Clumpy and Kloumpios may be spending the week at your place.

I see that samarium is also present in the monazite mineral, as well as neodymium. samaium also makes awfully good permanent magnets. So, by process of elimination, I guess it has to be samarium. -----Original Message----- From: ddhillma <[log in to unmask]> To: TechNet E-Mail Forum <[log in to unmask]>; Dennis Fritz <[log in to unmask]> Cc: TechNet <[log in to unmask]> Sent: Fri, Jul 29, 2011 8:18 am Subject: Re: [TN] NTC Friday Element Quiz - the Question Hi Denny! Well, you have the bonus question correct but I suggest further investigation/sleuthing on the element - neodymium is not correct.

Hillman <[log in to unmask]> To: TechNet <[log in to unmask]> Sent: Thu, Jul 28, 2011 5:39 pm Subject: [TN] NTC Friday Element Quiz - the Question Hi folks - Here is the Friday Element Quiz Question (this one may be ifficult): The Question: This element can be machined without sparking but as a pure metal is ompletely useless as it corrodes rapidly. No pure samples of this element ere produced until 1950 as it required ion-exchange chromatography echnique. This element is used in the production of the industry's best ermanent magnets. What element is being described? Bonus question: Who developed the ion-exchange chromatography technique as t applies to this element and what is the name of the University where he development happened? (both names are necessary for credit) here quiz winner will get the services of Clumpy and Kloumpios. And the riday Element Quiz Rules Arbitration Board has determined that if we get split answer as occurred last week with Robert and Graham, Clumpy and loumpios have to do tasks at both facilities. It is rumored that Clumpy nd Kloumpios were much happier assisting Robert than Graham (something bout furnishment of cold beverages as part of that task). o far Clumpy and Kloumpios have: Week 1 Lamar Young, SCS Coatings accomplished nothing (drank lots of coffee) Week 2 Bev Christian, RIM conducted REACH material testing Week 3 Drew Meyer, Benchmark Electronics Inc. Solderability testing and mowed the lawn Week 4 Ian Fox, Goodrich had an epic journey of travel Week 4 Gary Ferrari, Garrick Global unknown Week 5 Fredrick Miller, Astrolab unknown Week 6 David Nelson, Raytheon Were tackling dummys for Dallas Cowboys Week 7 Graham Collins, L3 Communications Cleaned gutters and painted window trim Week 8 Bill Noel, ITT Geospatial Systems Division unknown Week 9 Steve Gregory of RD Circuits unknown Week 10 David Bealer of Watchfire Signs descaled the in-line wash machine!
