GeoI actually tried moving the fine gain after initial coarse settings?Each time I move to the extreme?right,the scale reverts back to left.It was difficult to assess the movement of channel peaks

Good. No problems, I enjoy this 100%.It's good to have a collleague.FIRST- Calibration looks fine.Second- would you like to increase the gain and move the 50.54 peak off to near the right side? This

Geo Here is the Am 241 spectrum with the same settings. Sorry for the delay. As for scale error above I misquoted being way from my pc, On starting Dppmca? ,calibrating? and connecting to si pin,the

DudI have no access to the mca at this moment?So I cannot checkI will review?the mca tomorrow?I did cal with Bi and 59.5 with 2048Cal details are in the mca using notepadBut I do admit on

Looks like Taray calibrated with Bi XRF and 59.5 Gamma Ray then did this run.The low energies seem exact to me Dud. I don't know what the thing at ~49 is tho. Geo

Taray, These calibrates are not right for this run. Did you re cal when changing anything? Dud Sent: Sunday, November 1, 2020 6:24 AM To: [email protected] Subject: Re: [XRF] Chinese water filter

Geo I think it is Bi 10.84 and Am 59.5Taray

Can you send short only -Am looking at the sensor scan? 60 seconds.mca please?

Taray, send CAL data please picture of CAL or just the two channel/energy point #s.Geo

"Without any doubt there is lead in my drinking water"Hi Taray, a great application for the Si-PIN detector, thanks for setting up that experiment.Test everything! (you never know what you'll

Hi guys I repeated this test with additional RO discharge residue soaked in filter paper pressed against a yellow sample cap As a control I also checked a new dry filter paper with the cap Both

Charles, This is a classic example of what I have been trying to get across with respect to thermion, calibrations and interpretation You’re not exactly sure what you are looking at here because
