# User-Defined Designs¶

User-defined designs include all points from a specified candidate set.

Mixture Components: How many components are involved in this experiment?

Note

Fillers may be components too unless their proportion of the mixture is held constant.

Note

Components that will remain a constant proportion of the total can be added to the design by setting the low and high limits to the same value.

Total: The sum of all the components must equal the total for all runs.

Units: (optional) All components must use the same units of measurement. .

Note

Common units of measure include direct amounts (mass or volume), weight %, % volume by weight, and molecular equivalents.

Name: Provide names for the components to help with later documentation

Low: The lowest value a component can take (often zero).

High: The highest value a component can take (no larger than the Total)
