Hello, i would like to create a custom field, which i inject 5 standards. Each standard contains 5 peaks and one peak internal standard (total 6 peaks). Then i inject the second standard for % recovery. The calculation for each peak: (ARstd2/ARstd1)*(Wstd1/Wstd2)*100 ARstd2=Area(solvent)/Area(internal std) (of second…
I have the following four components: Single Peak 1 Single Peak 2 Single Peak 3 Named Group (which is a group of Peak 1, 2 and 3) Each individual peak also has a unique RRF: Peak 1 has an RRF of 1.0 Peak 2 has an RRF of 1.3 Peak 3 has an RRF of 1.5 The equation in my method is: (Sample Total Peak Area) / (Std Total Peak…
We have the "Photo Diode Array" option enabled on all of our projects. While the majority of our analysis does not require to use this feature, we do occasionally need to use it hence it being activated in all projects. When I open a Result Set or Sample Set in review it will automatically open the spectra window alongside…
Hi all, regarding the Report, is there any way to customize the component amount for STD and Control? I didn't find any way to do this using the "Sample Component amount group." Thanks.
Hi all, I create a Named Group (Know Imp Perc) and CF (Know Imp Percentage). Unfortunately, I don't have the sum results as expected (highlighted in yellow). Any help.
Hi I'm now and I like this forum so far
I found it I have no access to copy preference to other project in Configure System in Empower. Which privilege do I need?
My wash syringe leak test is failing after PM, only the strong side failed. No leaks were observed. Strong wash syringe replaced again, but the results are the same. Put the original syringe back on and still failing. Looking for ideas on what to try next
Hi! I'm a graduate student searching for answers for why the accumulator for our UPLC leaks all solvent to the seal wash (red circle). Normally our system runs at ~10000 psi but currently maxes out at ~200-300 psi. If I separate pump B/accumulator from the line, pump A works fine but when they are connected, both pumps…
Hi all, I traying to do a CF to calculate the ratio between STD (API = CCalRef1) and Internal STD (IS = CCalRef2). So I have de Ave_Area of STD and Ave_Area of IS. S%.%..AVE(CCalRef1[Area])/AVE(CCalRef2[Area]) But the CF is not working. Thanks.
