The Answer to Chromatography Quiz #36

The answer is column temperature was set too low. Column temperature has a big affect on retention time stability. That it is why it is important to use a column heater for your analytical methods. We have used this principle to our advantage with our column temperature gradient methods. Our fast amino acid methods use a column temperature gradient where the temperature is changed throughout the run. This has cut some of our older run times in half. Please note that these methods can only be run on our Pinnace or Onyx PCX. No other post-column systems have our repeatable temperature gradient capabilities. See our amino acid method abstracts for more details: https://www.pickeringlabs.com/library/method-abstracts-2/
