Chromatography Troubleshooting Videos

High Pump Backpressure.
High back-pressure in the system results in the pump working under greater resistance which will lead to an increase in the need for maintenance.  Learn how to locate the source of high backpressure in your HPLC system and resolve the problem in this quick video guide.



Irreproducible Retention Times.
Retention time shifts are not uncommon in GC, and the magnitude of the shift can be both highly significant and problematic.  Watch this troubleshooting video guide to which instrument and method parameters can cause short or long term irreproducibility, how to fix the problem, and avoid it occurring in the future.



Cycling Baselines.
This video shows Tony Taylor (Technical Director, Crawford Scientific) explaining how to use the CHROMacademy interactive HPLC Troubleshooter to identify potential causes for the problem.  He then discusses each of the potential causes, how they might affect the appearance of our baseline and what to do to avoid the problems happening again.



Peak Area Reproducibility.
Learn how to solve the problem of irreproducible peak areas, and how to avoid this issue in the future, with this troubleshooting video.  Irreproducible peak areas may not be immediately noticed until your data is analyzed as the peaks themselves may exhibit good shape and consistent retention times.  Variable peak areas can have numerous causes and may indicate a problem with the GC system itself.
