Baseline Dip using PA800 Plus SDS-MW Application by Priya Patel | Jul 13, 2023 | CE, Development, Questions, SCIEX OS softwareWe’ve noticed that with some gel buffer lots, we see a dip in the baseline at 280 nm when analyzing proteins per the SDS-MW protocol. Has anyone experienced this before? We don’t always see it and are wondering what causes the dip.
N-Methyl Pyrollidone by Suresh Narayanasamy | Jun 22, 2023 | Development, Pharma, QTRAP / Triple Quad, QuestionsI am in the process of analyzing nitrosamines using QTRAP. One of the difficulties in my sample preparation would be using NMP as solvent to dissolve the material. Is it safe to inject approximately 10ul of NMP is QTRAP??
Please provide at least 3 decimal places for expected retention time for scheduled MRM at EchoMS by Riyo Imamura | Jun 22, 2023 | Data acquisition, Echo MS, Questions, SCIEX OS software, TechnologyExpected retention time for scheduled MRM at EchoMS must have at least 3 decimal places, because the minute display with two decimal places is insufficient to show the difference in seconds. Thank you.
Standard peaks are noisy by Vasu Medikonda | May 17, 2023 | Industrial, QTRAP / Triple Quad, Questions, SCIEX OS softwareI am Using Sciex Qtrap 4500 for quantification of nitrosamines (NDMA&NDBA). I am facing issue with higher baseline intensity. When developed the method in APCI the basline was at about 5e4. but now even after cleaning the source (i.e. Changed capillary to new, Curtain plate & Corona needle cleaning, given blank injection overnight ), my base line decreased from 1e6 to 4 e5, but settled at 4 e5 from past 24 hours. can you suggest me how decrease my baseline intensity further to below 1e5. My standard peaks are like noise now.
