5.14 The molecular weight vs. response factor graph
The Molecular Weight Vs. Response Factor window, which can be useful
in checking valve function, displays a graph that consists of the following
information:
• Log (Molecular Weight) vs. Log (Response Factor) scatter plot graph
showing the actual measured values for the following "normal"
alkanes:
-Methane (C1)
-Ethane (C2)
-Propane (C3)
-Butane (C4)
-Pentane (C5)
• A trend line (best fit straight line);
Note
The ideal trend line would be linear.
• R-squared correlation coefficient.
Note
The closer RSq is to 1, the better.
