Here is the pure lead xrf..

Repeated xrf with an almost Pb . The peaks are almost the same. The calculation earlier was??on the X-ray goggles which may not??be accurate for escape peak analysis. Eesc for PbLb1

Some reference peaks..

Dude Pbin- Eesc=Pbesc Using centroid PbLb1 :12.62(uncertainty 1.73) Pbesc : 11.39(uncertainty 18.86) Eesc =12.62-11.39 ?? ? ? ? ? ? ? ??=1.23 keV Assuming there is Pbesc at left peak

Taray, I screwed that up. I looked at the 12.44 keV energy graph line thinking that was the peak energy. So 12.44 – (2* 0.511) = 11.42 keV which coincided with the unknown peak. The actual peak was

DudeCan you elaborate this 2rd ?Pb?escape peak ?Thanks?

Charles, look at Taray’s spectra using Log Y compared to your Linear Y. If you are looking for small confirming peaks always use a Log Y as its easy to miss things. With all your labels turned on it

Excellent application of labels! [email protected]> wrote:

If you wish to mark the escape peak you can create a label by double clicking one of the seldom used ones. If it is named Pbesc it will show up with all the other Pb labels when you toggle then

Charles? Ok noted the black (back) small print??in the software Either not paying enough attention or being absent minded.Probably both. It appears??only when no box is crossed . This will

Here is my interpretation with most of the peaks labelled. One image shows how to label the SrKb and ZrKa1 peaks to see both. [email protected]> wrote:

Charles? Ok When 2??major peaks are closeby,they overlap and not possible to identify elements. Under such circumstances,I have to some??do some manipulation??of peaks??so that both can

Taray Just a suggestion. It would be clearer to use large labels for Ka1 and smaller labels for the rest. Also, always show the Ka1 peak as well as Ka2 and Kb1. This helps verify the ID of the

Here is another glass. Going from black to white (colorless) X-ray goggles. I use??this when??I have to sit next to x-rays wearing only aprons in OT. My??own personal collection . So as

Here is the pic of the iron welding glass. Does not come with any welding glass?? grading system. Very dark . Repeated xrf Neodynium detected

The welding glass is very strong in Ba, Sr and Zr and the Sb must also have some function. Dud Sent: Wednesday, December 4, 2024 7:15 AM To: [email protected] Subject: Re: [XRF-Page-2] pseudo

My system has undergone some changes recently . Instead of a close compartment shielding,it is now more open with graded shielding done strategically. Radiation safety checks done with radiation
