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.
Dear team, I am facing %RSD failing problems in HPLC waters systems which leads to bracketing failures. Can u guide me what precautions need to take before to start of analysis. We observed that due to RT change only %RSD failures happens.bubble found on compression observed on display in log. We are taking all the…
I am trying to set up a processing method in Empower. I have 6 standard components, which are in equal concentration in Level 1, and then serially diluted 8 times to get 8 levels. Then to each I add the same amount of an internal standard. I am trying to figure out how to do this. * For the "Default Amounts" page, do I…
After processing my data and opening it in review the % deviation field in the "Peaks" tab remains un-populated, however the % deviation field in the "calibration curve window" contains the data. Why is the field in the peaks tab not populating?
I have created a custom field to display % deviation values from my bracketed standards in the peaks tab for the purpose of making data review more convenient for my users. I have used the following calculation: %.%.%((Entered X Value(Area/B)/Entered X Value)*100, Search order: Result Set Only, Sample Type: Standards Only.…
Is it possible to set up a Report Method that only reports certain peaks within a sample exceeding a certain threshold?
I have a sample set like Blnk 1A Blnk 1B Smpl 1 Smpl 2 Blnk 2A Blnk 2B Smpl 3 Smpl 4 I need to subtract the average Amount of Blnk 1A and Blnk 1B from Smpl 1 and Smpl 2 and then subtract the average Amount of Blnk 2A and Blnk 2B from Smpl 3 and Smpl 4. Is it possible to create just one CF that calculates the average Amount…
