Can you see vitamins and minerals on microscopes ?

#1 Post by Kalleboy » Sat Jan 14, 2017 8:38 am

Hi
Can you see vitamins and minerals on microscopes ?
- Like: B12, Omega 3, Zinc, Copper, Magnesium, Iron, C, A, D, Ginseng, and such ?
  • How to identify them ? (Crushing pills, berries,...)
  • Can I count them so I can prove certain vitamin products/pills really have what is written on their contents: like 100mg, 10mg of that and that ?

Hello,
You can not see the individual vitamin molecules and also not minerals. They are way too small. You can crystallize the vitamins, however and observe them under polarized light. And this is indeed an interesting thing to do with a microscope.

I am sorry, but you have been asking many of those kinds of questions without even trying to Google.

I pretended that I did not know the answer and googled "chemical microscope" and found answer (polzarized light) in the first two pages of search results.

Or please read a beginner book about microscopy first. That way you learn more.

No, you cannot quantify active ingredients in a medicine bill without using analytical chemistry instruments, such as HPLC and MS. Microscope is usually not considered as an analytical chemistry instrument.

You can detect the presance of many specific vitamins with microscopic observations of the concentration of numerous protozoa in a specific volume of fluid these protozoa are suspended in.

Certain species of Euglena flagelates 'used to be used' for detection of concentration of vitamin B12 in solutions or source substances being evaluated for B12 content. This bioassay method is extremely accurate. But you first need a known standard B12 concentration solution, you first need absurdly precise sources of organism and it's culture fluid.

These bioassays are too tedious and now more direct means exist to quantitatively 'see vitamins' in unknown source substances.

When you dip a strip of litmus paper into a water sample..you are 'seeing results of hydrogen ion concentration'..you are not 'seeing hydrogen ions'.

Ok thanks.
Seems microscopes are pretty much way over hyped.(watching too many science movies)
I'll just stick to watching coins and rocks.
Was hoping to use it for more exciting works. People just suggest watching pond "animals" or yeast growing which to me are very boring and pointless things to do ;) .

Well....
One of my major interests is too look at crystals of different substances (e.g. vitamins), normally using crossed polaroid filters.
Sure you can't see the atoms or the molecules but you can see a lot very interesting things like the huge variety of crystaline forms and amazing colours.
You can also watch the crystals grow, which you know, even if you can't see, is due to the molecules coming out of solutions and adhering to the surfaces of the molecules.
Its really fun and quite addictive.

Occationally you can see the effects of molecules. Brownian motion can be viewed in various ways (try googling, searching this forum).
I have sometimes seen this with very small crystals. Its amazing.
I saw the faces fo the crystals turning and giggling around due collisions with the solution's molecules.

You could make a spectrophotometer to detect whether certain substances are in the pills, but you would not be able to get an accurate count of how much of each substance is in each pill purely by spectrophotometry.

You might be able to crush the pills into a powder and use a centrifuge at varying G loads to separate each substance into layers, but I don't have any experience with this. There may be other more simple ways of doing this too.

What could be BORING AND POINTLESS about searching for and observing pond "animals"????.. You need to get a different hobby!!...

Guys, this is an old post that has been resurrected.
Original poster has not posted in a while. Let it be.
