Column Temperature Control

Rugged chromatographic methods ensure success for routine analysis. The effects of temperature control offer the benefit of stabilized retention times which are both rugged and reproducible. Lower column back pressure is also achieved when heating your mobile phase, due to a decrease in liquid viscosity. This enables more efficient use of high pressure and ultra-high pressure columns and devices which are becoming the standard in today’s industry.

So, which column heater is the best for your application? Three important factors should be considered when deciding:

Temperature repeatability, or the capability of the heater to reliably heat to the same set temperature time and again.

Temperature stability, which is the ability to maintain consistent temperature balance through the entire course of your method, and

Temperature accuracy - the degree of closeness of a heater’s actual temperature compared to the temperature you set. Keep in mind that the lower the stated specifications are, the better the heater performance. Typical heaters have an accuracy of ± 0.5 ºC which could potentially result in a full 1ºC swing in the actual temperature reading. Heaters with an accuracy of ± 0.1 ºC, such as those from Analytical Sales and Services, would potentially have a swing of only 0.2 degrees.
