B.2.4 Representation of a gas chromatograph Component ToC Previous Next

The concentration of a given Component and its related characteristics are represented using a Parameter of a type derived from EngineeringValueType.

The Value DataType is Float and its ValueRank is -1 because it is a scalar.

All components of this Variable are read-only.

Table 111 and Table 112 illustrate two example definitions of types that represent gas chromatograph Components.
