modelling clay

taray singh #1906 Hi guys I sometimes? use? modelling clay as a mount to hold odd shape samples . This "clay"? is usually made of? ?calcium salts,petroleum jelly and aliphatic? acids. This xrf is? for a red clay. The xrf show a prominent calcium peak. This show si pin detectors can detect Ca clearly There may some other peaks due to the pigment used There could be a sinister Pb? peak but the count rates are low Taray modelling clay.mca modelling clay.mca modelling clay.PNG
[email protected] All Messages By This Member #1907 Thanks Taray, good on the calcium, yes it is definitely in the range of a Si-PIN, Usually the peak is cluttered and had to see in dense objects but just the other day there was a sample here that was predominately Ca and it was good to? see that old friend.
