We were interested in the change in the intensity of the analytical signal at different interface temperatures.
A standard solution of alkanes was prepared for the experiment. Testing interface was carried out in the range of 200-300 °C. Injector temperature - 250 °C. The furnace temperature ramp was set at a rate of 10 °C min from 50 °C to 220 °C. Ion source temperature - 200 °C. Perkin Elmer Clarus 600T.
Finally, it was found that at higher temperatures, the intensity of the analytical signal decreases. The area of the peaks is also decreasing. We noticed that the retention time is slightly increasing
Could it be memory effects? Сan it affect the fact that the column has a temperature lower than the connecting line? Is it possible that due to the fact that helium heats up and expands at higher temperatures, we observe a similar image?
If you know any literature on this topic, then please share it. Thanks for the answer
