custom field and unknown peak amount calculation
I need to calculate sample concentration based on the formula, %v/v= (sample area/ standard area -sample area)x standard concentration/10000. I made a custom field: Area/((S01.%.(Area)-Area))*cconst1/10000. I specified the standard concentration of cconst1 in processing method. This custom field only works for the named peaks which have corresponding standard peaks in the standard. Is there a way to build a custom field that can calculate all the unspecified/unnamed peaks in my sample based on a particular standard peak? check default peak in processing method doesn't work.
