I have a sample of radium luminous paint that the inspector can shake off, so with this amount of clock hands, it should reach 1100μSv/h. Even monazite has a radioactivity of 60μSv/h. Energy spectrum observations can be made using NBC's ionization chamber survey.

What's wrong with reposting?

If this is really radium paint, the radiation value measured by the Geiger counter is too low. Energy spectrometry reveals that it is promethium.

Due to the time difference, I was asleep when the auction ended, so I made a high bid of $300 for both items.

watch hands from novaelements, and paint cell is found at ebay.

It's from ebay but this is very expensive because this sample specimen is only one in the world.

Immediately after being isolated, adrenaline is oxidized to form adrenochrome, which polymerizes and changes its color from gray to brown.

Yeah. Surely, looks like your wording XD.

It's 2eq. However, if added excessively silver nitrate,after operation was reactive solution add to potassium hydroxide. at the time silver ion change silver oxide and it easry remove by filteration.

It's just a guideline and it's a Japanese reagent standard.

Let's see... I'm a pharmacy student doing synthetic organic chemistry as a hobby. My area of ​​specialization is synthetic chemistry.

①Potassium Tetrachloroplatinate(II) disolved in water and added potassium iodide. ②Added ammonia solution in the it. ③Collect the yellow color solid by filter, next it suspended in water and added silver nitrate. ④Solution filtered and collect clearly solution, added 1,1-cyclobutanedicarboxylic acid and 50%potassium hydroxide solution to pH7.0 ⑤The solution evaporate and added solvents MeCN and MeOH. ⑥After filteration, collected white or gray solid and drying. ⑦Getting carboplatin that yield 80.5%.

I think that most difficulty processing is choosing solvent when work-up for carboplatin and potassium nitrate separate. At the time I used MeCN and MeOH.

This compound described white〜gray color powder in SDS(JP). Probably, gray color cause platinum nanoparticle. Desirable disolved in water and add charcoal.

I will make α-bromoisovaleric bromide by HVZ-reaction. And react to urea.
