Abstract
A heating system for preheating a fluid. The heating system comprises a heating unit with a heating flow path; wherein the heating unit is adapted to be operated at a first temperature and to provide a heat transfer between the heating unit and the fluid passing through the heating flow path, with the heat transfer not being sufficient for heating up the fluid passing through the heating flow path to the first temperature.
Claims17
A heating system for preheating a fluid, comprising:
- a heating unit with a heating flow path;
- wherein the heating unit is adapted to be operated at a first temperature and to provide a heat transfer between the heating unit and the fluid passing through the heating flow path, with the heat transfer not being sufficient for heating up the fluid passing through the heating flow path to the first temperature.
A separation system comprising:
- a heating unit for preheating a fluid, the heating unit comprising a heating flow path, wherein the heating unit is adapted to be operated at a first temperature and to provide a heat transfer between the heating unit and the fluid passing through the heating flow path, with the heat transfer not being sufficient for heating up the fluid passing through the heating flow path to the first temperature;
- and
- a separation column adapted for separating compounds of a fluid sample, with the heating flow path's outlet being fluidically coupled with the separation column's inlet.
The separation system of claim 8, further comprising at least feature selected from the group consisting of:
- a fluid delivery unit, preferably a pump, located upstream of the heating unit and being adapted for moving the fluid in the separation system;
- a sample injection unit located upstream of the heating unit and being adapted for injecting the fluid sample into a mobile phase of the separation system;
- a detector located downstream of the separation column and being adapted for detecting separated compounds of the fluid sample;
- and
- a controller adapted for controlling operation of the separation system.
The separation system of claim 13, further comprising at least one feature selected from the group consisting of:
- a sample injection unit located between the main heating unit and the auxiliary heating unit, the sample injection unit being adapted for injecting the fluid sample into a mobile phase of the separation system;
- and
- a sample heating unit adapted for preheating the fluid sample before the fluid sample is provided to the sample injection unit.
A method for preheating a fluid, the method comprising:
- conveying the fluid through a heating unit, the heating unit being kept at a first temperature, with the heat transfer during the fluid's passage through the heating unit not being sufficient for bringing the fluid's temperature to the first temperature;
- and
- supplying the fluid to a separation system.
The method of claim 15, wherein composition of the fluid conveyed through the heating unit is varied according to a gradient.
The method of claim 15, wherein composition of the fluid conveyed through the heating unit is kept constant.
