Abstract
A flow cell (200) for a sample separation apparatus (10) for separating components of a sample fluid in a mobile phase, the flow cell (200) being configured for detecting the separated components and comprising a tubing (202) having an inner wall (204) and an outer wall (206), the inner wall (204) defining a lumen (208) for conducting the sample fluid, the tubing (202) further having at one end an end face (210), and a detection unit (212) configured for detecting electromagnetic radiation (214) exiting the end face (210) after propagation of the electromagnetic radiation (214) through the sample fluid in a portion of the lumen (208) and through a portion of the tubing (202) between the inner wall (204) and the outer wall (206).
Claims26
A flow cell for a sample separation apparatus for separating components of a sample fluid in a mobile phase, the flow cell being configured for detecting the separated components and comprising:
- a tubing having an inner wall and an outer wall, the inner wall defining a lumen for conducting the sample fluid, the tubing further having at one end an end face;
- and
- a detection unit configured for detecting electromagnetic radiation exiting the end face after propagation of the electromagnetic radiation through the sample fluid in a portion of the lumen and through a portion of the tubing between the inner wall and the outer wall.

A method of detecting separated components of a sample fluid in a mobile phase, the method comprising:
- conducting the separated sample fluid through a lumen of a flow cell comprising a tubing having an inner wall and an outer wall, the inner wall defining the lumen, the tubing further having at one end an end face;
- and
- detecting electromagnetic radiation exiting the end face after propagation of the electromagnetic radiation through the sample fluid in a portion of the lumen and through a portion of the tubing between the inner wall and the outer wall.
