Standard component concentration*sample component area/(sample weight*(standard component area-sample component area))
This is a straight forward calc but when dealing with multiple solvents I'm running into issues because each component is added individually to the a portion of the sample solution so I'm comparing multiple standard to one sample, and if the sample has more than one solvent it's going to calculate the one I'm not considering with that standard. I would love to be able to perform this calc as a calibrate/quantitate function in the sample set, but it won't work with the way empower does "calibrate" even changing the x/y variables in the processing method (unless I'm missing something, some magical property of empower that's evaded me).
I've gone through several iterations of this calc in my attempts, but those that have experienced empower software know it's not the most user friendly thing and is beyond vague in its help topics.
My next attempt will be trying to use the standard amounts to cancel out sample matrix peaks in the standard:
ResSolv = (S%..(CCompRef1[Amount])*CCompRef1[Area])/(Sample weight*(S%..(CCompRef1[Area])-CCompRef1[Area]))
Plugging 0 into the standard amount for components that aren't in the respective standard. Not sure exactly how empower will treat this, if it will complete the calc and if it does how it will report the result, average, highest value or what.
Any input would be greatly appreciated, if you have a single point standard addition calc that works with multiple components and samples and your willing to share that would be awesome.
