AI Technical Summary

Technical Problem

In existing chromatographs, after heating is stopped, the actual temperature range of the chromatographic column is higher than the target temperature, which leads to a decrease in the accuracy of temperature retention time and affects the normal precipitation of components in the mixture.

Method used

By analyzing the sample type and the initial temperature of the column, the window heating rate and target temperature are determined. The operation of the heating and cooling components is controlled to ensure that the column temperature is consistent with the target temperature. The temperature difference inside the column oven is adjusted using the evacuation and purging components and controlled within the standard range.

Benefits of technology

It improves the precision of column temperature control, ensures the normal precipitation of components in the mixture, reduces the temperature fluctuation range, and enhances the accuracy of analysis.
