Abstract
Systems and methods for determining a boiling point distribution of a sample include controlling the rates of temperature increase for a column and an injection port. An analyzer includes a column having a column heating element and an injection port having an injection port heating element. The temperature of the column can be increased at a first rate, and a temperature of the injection port can be increased at a second rate. The first and second rates are selected such that the temperature of the injection port is within about five to fifteen degrees Celsius of the temperature of the column when the temperature of the injection port reaches a target temperature of minimal thermal decomposition.
