Re: Rolling Bracket Recovery by Custom Field
This can be done quite easily by altering your labels slightly. Label the bracket standards as SB02 and SB03. Then create a peak real CF with results set only search order and formula: (S0101.%..AVE(…1 -
Re: Reporting Custom Field Values
Check the sample type and peak type of your custom fields. They should be set to All for all your custom fields so that standard custom field values can still be applied to unknown and control sample…1 -
Re: Bracket Standard Recovery
That's tricky because I cant think of a label system which wont affect the order in which you run the standards, the label for "after" is going to overlap with the next set of samples and b…1 -
Re: SST Difference
Ok so the formula can then become: ((CConst7-D0101.1.(Area)/CConst7*100)*EQ(Label,"D010")+NEQ(Label,"D0101")*-1*50000 or if you only have one active peak, set it in CCalRef1 of yo…1 -
Re: SST Difference
Instead of using CConst7 and to be more accurate, can you label the sample where you get the Initial Area from, for example Ref, and then make a peak, real CF result set only search order, formula: (…1 -
Re: I need a custom field equation in Empower 3
Peak, Real, Calculated custom field. Set Sample Type to All and Peak Type to All. Search Order is typically Result Set Only which means you process a sample set to generate a result set. You will nee…1 -
I need a custom field equation in Empower 3
Hello I want a custom field equation to calculate % amount: % amount= (AREA OF STANDARDS / AREA OF UNKNOWN SAMPLES) * 100 Note: 1- I inject 6 standards in the beginning of the sequence then 3 unknown…1 -
Re: Tricky custom field required
That is sad. I would think it should work one way or another. Maybe something to ask Neil Lander in one of his tip of the week posts :)1 -
Re: Performing Internal Standard Calibration and Quantitation
Set your CCompRef1 to the name of the internal standard component. If you need the AVE of the area make your custom field as a: IS%.%..AVE(CCompRef1[Area]) Add the summarize custom field to your samp…1 -
Re: Impurity calculation for unknow Impurity and Total Impurity calculation
I dont think that exists as default but if you want to use the Dilution or Sampleweights fields to "back calculate" that calculation then try and invert the Real_Concentration * 100 section…1
