Which method dry ashing or wet digestion is suitable for determining minerals in liquid supplements???

Can I use this method to detect heavy metals from cosmetics products like eyeshadow...or should I use wet digestion method

So satisfying to watch.

Hello! I just wanted to ask - what is the purpose of the filtering step? What is being filtered out? Thank you!

@MicroChemsExperiments

Filtration is done to ensure that any sort of interference will be filtered out, if any, present in the Ash. Ash particles, which are not dissolved in the diluent, may be filtered out.

I plan to measure ash content and then measure mineral content and also heavy metals. For heavy metals i would like to use wet digestion method. In your opinion, do i need to make a wet digestion if i already drying ash from measuring ash content before? Thanks in advance!

Yes. For heavy metal analysis, wet digestion is better method than the dry ashing.

If I do dry ashing before and use AAS next day, can I do like that? And what should I do? Because i don't have time enough for it. Thanks for answering

Keep the Ash sample closed to avoid contamination and prepare the sample from ash on the day of analysis in AAS. Or you can keep and store the prepared solution at 4-8 degree Celsius.

@MicroChemsExperiments

You are right. Presence of Black color means that the sample still contains organic matters. At this point we add some acid. This addition of acid facilitates to break down the Carbon strong bonds making free carbon which can easily be removed from the sample by applying additional heat.
