Adapting a SCIEX high flow source for microflow LC by Christie Hunter | Sep 20, 2021 | Data acquisition, Development, Ion sources, LC, Life Science Research, Metabolomics, Pharma, Proteomics, SCIEX informationTo set up a SCIEX high flow source for microflow LC (Turbo V ion source, DuoSpray source or IonDrive Turbo V ion source), first you must replace the wider bore electrodes with more narrow bore hybrid electrodes. Note with the OptiFlow Turbo V ion sources, there are...
Troubleshooting low flow LC – LC-MS peak area is lower than expected by Christie Hunter | Sep 20, 2021 | Data acquisition, LC, Life Science Research, Optimizing Performance, Proteomics, SCIEX informationSymptom: LC-MS peptide peak are is smaller than expected in PepCalMix Test Test: Use PepCalMix Infusion tests to determine if it is a problem with LC or MS Solution: First perform the SCIEX recommended performance tests using infusion on your MS system. If these...
Troubleshooting low flow LC – Spread of peptide elution is compressed or delayed by Christie Hunter | Sep 20, 2021 | Data acquisition, LC, Life Science Research, Optimizing Performance, Proteomics, SCIEX informationSymptom: The observed retention times of the peptides eluting are compressed, are not as spread out as expected, suggesting the elution gradient is compressed Test: Use PepCalMix LC-MS test to check the peptide elution time and spread Solution: Make sure you are...
Troubleshooting low flow LC – Loss of early eluting peptides during trap-elute workflow by Christie Hunter | Sep 20, 2021 | Data acquisition, LC, Life Science Research, Optimizing Performance, Proteomics, QTOF, SCIEX information, ZenoTOF 7600 systemSymptom: Early eluting peptides are missing (based on monitoring PepCalMix LC-MS test or observing a change in the shape of the proteome TIC). Test: Use PepCalMix LC-MS test to monitor binding of early eluting peptides. There are a number of very hydrophilic peptides...
