Operation
4.1.2 Load state
During the load state, the sample loop is being filled with sample. When the valve
switches back to the inject state, the sample flowing through the sample loop is
trapped momentarily.
This sample, whose volume can be calculated from the length and inner diameter of the
tubing used, is swept on the manifold by carrier for reaction and analysis. Refer to
Figure 27.
