I see what you did there.

I bought new wedding bands for my wife and myself off of ebay that are tungsten carbide. They were something like $25 each. Did some research on Wikipedia and saw this:
Many manufacturers of this emerging jewelry state that the use of a cobalt binder may cause unwanted reactions between the cobalt and the natural oils on human skin. Skin oils cause the cobalt to leach from the material. This is said to cause possible irritation of the skin and permanent staining of the jewelry itself. Many manufacturers now advertise that their jewelry is "cobalt free". This is achieved by replacing the cobalt with nickel as a binder
Naturally I was worried I had this colbat infested crap, so luckily in our reliability lab we have a SEM. Had the guy measure it for me, and it shows up as 86% W, 14% Ni
Woot!

I take it they used EDS?
Thats fine as long as you aren't allergic to nickel...
Liquid nitrogen is always fun
Pro tip-
1) don't drink it
2) don't throw it on the floor when a lab tech from another lab is in. This happened to a mate (after I had told him about "disposing" of excess - its safer than leaving it around for noob students to spill on themselves). The tech went a bit mental

Spilling it on the floor is a great idea! Go into a hallway with a bucket of the stuff, and spill/throw it down the hall. The nitrogen will flow all the way to the end of the hall picking up ALL the dirt and dust and carrying it with it. You could spend an hour sweeping and not do as good a job as the LN2 does in 10 seconds.

if your ring is a W-Ni alloy, then it's not tungsten carbide (WC and W2C)
and actually, your ring was most likely measured using EDS or WDS (energy and wave dispersive spectroscopy), which are extended functions of an SEM

I can retain the services of our firm (I work for lawyers) for free up to a point. That point would be when it starts costing the firm more than just time or too much time. If we had to litigate I imagine they would want at least part of the going fee.
Last year this netted me approximately $3000 extra when someone slammed into my vehicle and totaled it with me in it.
Of course if I was the defendant in a criminal case beyond a fist fight or something really minor there is a high probability I would be terminated
Other than that I get to raid whatever computers die or just get too old.

Free EKG's, Echo's, and Sono's if I want them.
My wife can buy drugs at hospital costs...actually a pretty nice perk for some things. We compound our own diaper cream by buying the ingredients individually. You can make half a gallon for around $15. Compare that to like $5 or more for a little couple ounce tube that doesn't work half as well.
