We are trying to develop some new routines in our lab and we would like to use Iolite for data processing. We are trying to create/modify a DRS but we are founding some problems.
The first one is related to δ values (“delta values” – I hope you could see the symbol properly). We want the δ to be calculated directly by using the DRS, and for that purpose, it is necessary to divide “sample ratio wave” by “reference standard ratio wave”. However, we are not able to do it… Is there any specific function to do it?
Additionally, we would like to know if it is possible to make the baseline subtraction only in some of the waves? We are using liquid standard (continuously introduced) together with the laser input in order to correct mass fractionation of the unknown. If we select a baseline integration time to subtract it to the main signal for the lasers’ input channels, those time ranges are used also to calculate the ratios of the standard. But as we mentioned before, the liquid standard is continuously introduced, so the “baseline” and the “main beam” are the same signal, i.e. if we subtract the baseline to the main beam it results in zero.
We have thought that by using a high enough standard concentration the blank levels could be discarded in solution. However, the blank introduced by the laser system could be also significant in some cases.
So is it possible to subtract the baseline in some masses and to use the signals without baseline subtraction in others?
Thank you in advance. Best regards,
