Hi all, I am using a GC 6890 with split/splitless inlet to analyse reaction products. I installed a 60 m column in the GC and while running my usual method ,the GC shut down because of - Front Inlet Pressure Shutdown-. I revised the possible causes of this problem and thought that this might be a leak problem. I tried and "unobtrusive" leak… Show more
Hi I am building a complicated quantitation method using Masshunter. I have 65 analytes and 15 internal standards. The concentration of my analytes ranges from 10ng/mL to 500ng/mL, depending on the analyte, while the concentration of my ISTDs ranges from 200ng/mL to 1,000ng/mL. When I build my quant method I assign calibration levels to my… Show more
Hello , I'm using openlab chemstation edition software version C 01.07.SR2 and i'd like to create a sequence summary report which report the calibration curves and then the interval confidence of regression line. My sequence have 5 level of calibration with 3 run for level i'll try to create an IR based on calibration.rdl template.but the problem… Show more
(Running OpenLAB CDS Chemstation Edition, version C.01.07 SR1; with ECM) We have written into our SOPs that the data file and the sample name must match. This was done to provide another layer of data integrity. We also have a rule that system suitability must be verified as passing prior to injecting any samples. This leads us to create a lot… Show more
In MH Quant, is it possible via custom calculation (manual is really lacking on how this function works....) or some other function, to determine the concentration of compound B by using CF Formula of compound A (using same ISTD and ISTD normalized response ratios)? Thanks!
Hello: I am using Open Lab CDS C.01.05[35} There are several things I would like to be able to do. I am using a Seq. Summary Report Extended and I have added a column to the Percent Area Report to provide Concentration. Is there a way I can add another column that will provide % concentration (similar to Area %)? Using the Percent Area… Show more
