will trade 500 grams of >50% In Alloy for analysis of the alloy

zephler1 - 9-4-2015 at 14:31

I have 9 samples of an Indium alloy that is well over 50% In (probably close to 75%), as well as one sample that I believe to be 99% In. However, I am wondering if someone with access to an AA or an ICP would be willing to trade the analysis of 9 samples of the alloy (turnings), and an analysis of the 99% for Indium content for one of the 500 gram bars (of the alloy). That means you would be getting more than 250 grams of Indium for perhaps an hour or two's worth of work?

Feel free to PM me if interested! Thanks!

Indium Corp. of America?

I have a couple of "mystery ingots" myself.

Hi Bert,

LOL - "mystery ingots". No, they were a bunch of scraps from a CIGS Solar operation at one point. I've had them for 10+ years from my days as an electronics scrap cowboy and recently with the price of indium going up, I've melted them into 500 gram ingots using the old "muffin ingot" tray. My data sheet with them is missing a few values, but I would like to get a number from this decade on these new tasty looking metal snacks.

What's supposed to be the remainder of the alloy?

50 -70% Indium / 40 - 20% Gallium / 10% Copper / <1% Selenium

How accurate do you need the analysis? I use a handheld XRF spectrometer (Niton XLp) at work daily and could easily check out your alloy. However it doesn't provide more than one decimal point (I think? It may be two, when I think of it) of accuracy and I'm not sure how accurate it actually is.

I have access to an AA but only for a few more weeks and I don't think we have an In tube :(. Maybe in a few months though.

ICP-MS ok?

One decimal point is fine! Thanks for the reply - I will message you.
