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?

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?

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....

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?

I have previously downloaded this Fp software manual.

It helps me understand the limitations of Dpmcca

Taray,

So why don't you let this run for a long time so you can get some decent counts?? Se is almost certainly there but to identify the other peaks with certainty you will need more than 1024 seconds.

Not a long spectrum..

Good idea, and the calibration points can be radioactive source, or XRF made by exciter.

This last way you can place the cal peak anywhere you wat, up to the limit of your exciter, simply by using pure elements. One very low and one at 59.5 is really all that is needed due to Si-PIN linearity.

Try this:?After an important long run, save the .mca and a BAK.mca of it, change DPPMCA time to longer and add 59.5 source for how long it takes to get a good solid peak at 95.5 and 13.95 or 17.750keV, all the while leaving the original scan on the screen. Save and label this as?"xxxxx"-Post-Run-Am-Cal.mca and use it to tweak the calibration of earlier saved .mca, or as proof of linearity later.?

That's why to include 0-62? keV even though you might have no peaks above ~32 etc. Just set RANGE boxes to highlight the area where the peaks are, maybe 2 to 35 keV.

Also must add, any "drift" in calibration is usually not drift at all, but the maturing of the peak from start to finish to a point where the actual peak is at more clear. In most cases after days of running it may only be a +/- 1 channel change.

Is there an issue/question? with cooling/heatsink?? What you feel on case should be warm like a puppy. This is the 1 Watt or so of heat being removed from the sensor chip inside the tip behind the Be window, which operates in a vacuum at? ~230K = minus 43C.

My SDD sensor has a more sophisticated cooler, it uses a liquid? filled "heat-pipe" to bring heat inside the main box from the tip, a heatsink and fan inside the box to cool it down and blow it away from the sensor end. In a way heat pipe is same idea as a cold finger on HPGe sensors. Heat pipe also = Drinking Bird toy tech.
