Creating Gas Project Properties
Overview
Gas project properties are designed to enable you to create your own gas properties in p:IGI+. To define a gas project property you need to provide very similar information to a standard project property. Gas properties can only be of numerical type.

How to use in practice
Creating gas project properties
Creating gas project properties works in a very similar manner to the creation of standard properties, however additional information must be provided for each of the gas property indicators. The gas property indicators are used to describe whether the gas proportion is measured as a volume, mass or mol fraction, and includes an unknown fraction for data of unknown source.
For each indicator it is necessary to define the units to use. We strongly advise that for gas data you retain the unit groups we provide by default. These are really the only sensible unit groups for their indicators. However it is reasonable to select the default unit, and change this if you wish. By default we select parts per million as the default units.
Note that equations can also be defined for gas properties. If you create a ratio of two, or more, gas properties then we strongly suggest giving each the same ratio type. It is useful to be able to define where the ratio is in terms of volume, mass or mol fraction, since these can be quite different for gases with different molecular mass.
Using and sharing gas project properties
Gas project properties can be used and shared like any other gas property.
