Aspen Inferential Qualities
Measure Product Quality without Costly Lab Analysis.
Reduce off-spec product and ensure faster, more reliable quality measurements with Aspen Inferential Qualities. Now you can implement on-line linear or non-linear inferential sensors that provide real-time estimates of unmeasured properties while reducing expensive, time-consuming lab work.

Improve control with feedback between lab samples.

Augment costly or infrequent lab analysis with continuous prediction of key process variables. Infential measurements improve input information to the controller and reduce your reliance on laboratory analysis.

Simplify usability with zero-code configuration.

Valuable information is often lost in translation between those that configure code and those that operate processes. The AspenTech solution requires no programing, no nested code, no hidden routines, no maintenance nightmares.
