calculating a new input channel

jdavies1

I am trying to process some Hf isotope data, but we did not collect mass 171 on our mass spec. I tried to create a new input channel by calculating the 171Yb mass based on the 172Yb intensity. I saved it as an input channel, however it doesn't recognise it when i run the Hafnium DRS.

I suspect your calculator channel is not working because the DRS is looking up the channels by their mass (rather than their name). You could run the following two lines of code in the iolite's Python Workspace, and it will update the mass of your calculator channel:

Yb171 = data.timeSeries("Yb171")
Yb171.setProperty("Mass", 171)

Obviously, this is a little cumbersome. If you could send us some example data, I could take a look at what might make things a little quicker/easier for you. It might be as simple as adding a couple of lines to the python version of the Hf Isotopes DRS.
