We have an ELAN 6000 that seems to behave a bit strange sometimes. What
happens is that when we run a sample an for a given element and have a
stable signal, suddenly one reading gives "S" which means that the signal
is higher than can be read in pulse counting mode (>2.000.000 cps). It can
happen with only one reading in a long line of readings around 50.000 cps.
This also happens when I look at two different isotopes of the same
element, with short dwell time, then suddenly for one of the isotopes in
one reading "S" appears???
It seems unlikely that it actually should give this high readings (from a
particle etc.) just in 10 ms on one isotope of an element (It happens with
many different elements).
Have any of You Elan 6000 users out there experienced anything like this?
Can anyone tell me why this happens or if there is anything to do to avoid
Thanks for Your reply.
