I do see some small peaks on extreme left with my 1024 settings.

1.85 is probably silicon escape peak.

Argon not??emphasized yet

I will check out with ur??methods above.

Titanium too maybe in white paint.

There are other things I am still learning?

Slow learner I guess?

Hey why don’t you scan ur??

?iron supplements to see what comes out through the container?

Yes low energy limits on Si-PIN, are you seeing Argon gas in your scans? Comes from air, ionized by alpha particles. Paper filter on exciter helps, also lightweight gas purge, even just a small fan.

? Possible to see Ti not in sample but in your environment too. I traced it down to the material on top of the desk, pigment included Ti oxide....

Test everything

There are supplements in oxide form.

One example is Magnesium oxide?

Not well absorbed but due to huge Mg load will overcome this obstacle?

Mg??oxide supplements may be friendly to xrf .

But Si pin don’t reciprocate?

Thanks for the explanation of the molecules Taray!? This is important and answers some questions about confusing scans of mine on similar items.

Test everything.

Hi guys
Drug companies label their supplements by molecular weight of the compound.

?

So the actual amount of? study element will vary from one compound to another .

?

For example 100 mg of Zn oxide will contain more Zn? than 100 mg of Zn citrate.

?

Most drugs are weak acids or bases to aid in gut absorption.In this case this is Zn citrate...a weak acid

?

But this will increase their molecular weight with less? study element for the same weight of drug

?

This may be good for the drug but bad for xrf.

?

Drug? companies? produce supplements which are safe ,stable and bioavailable.

?

Xrf is never in the picture.

?

Furthermore? most of these oral supplements consist of? a chemical matrix of low Z? ingredients in the capsule and? the powder within.

?

Altogether? this high molecular weight drugs within a loose matrix will dilute the elements for xrf

?

Despite? this , I can? still can do a qualitative xrf check for the mineral element by just scanning though the plastic bottle? with si pin.

?

No need for an elaborate lab analysis .

?

But the downside is I am not able to detect? ?

?

supplements containing lower Z such as boron,calcium or magnesium.

?

Here is a scan for Lifeextension Zinc capsules?
