QUBICON – Quality by Control

QUBICON® – Quality by Control
Software Solution for Advanced Process Monitoring and Control

Qubicon: Quality by Control software


Qubicon® is a software that enables advanced real-time monitoring and control of processes in a flexible way. Qubicon® offers data-alignment, processing, management and reporting as well as the use of user-defined control strategies, the implementation of software-sensors and a flexible way to combine equipment, sensors and actors. On-line and off-line data integration allows real-time visualization and analysis as well as quick and straightforward comparison of different live-processes or live and historical ones (golden-batch).


The web-based software runs on a server infrastructure on-premise and can be accessed via clients. The complete user interface is in English language. A flexible database, representing the heart of Qubicon®, enables easy integration of new equipment and measuring devices (e.g. PAT-sensors).

Qubicon® has been designed with the industry’s priorities in mind. It makes advanced planning, execution and analysis of processes intuitive. The modular architecture of Qubicon® allows custom-tailored implementation of functionalities needed in the user‘s workflow.

Qubicon® ultimately enables the implementation of the "Quality by Control" concept to bioprocesses.

Quality cannot be tested into products;
it should be built-in or should be by design.

Qubicon Features

Flexible hardware setup

The heart of Qubicon® is a database, storing and managing data from different sources. Process equipment is connected to the Qubicon® server via Ethernet and provides the signals via the communication standard OPC-UA, either directly or via the communication bridge PAT-Box. Qubicon® supports the integration of up to 100 process entities, delivering data at varying time intervals.

In addition, off-line measured values can be imported either manually or via an import function. The thus acquired additional data is then correctly time-aligned within Qubicon®, enabling the export of complete datasets. Accordingly, the data can be directly used for statistical analyses or model development in the user's standard environment without prior manual processing.

Advanced monitoring and control

Developed process models or soft-sensors can be integrated into Qubicon® using the Python scripting language or model runtime files. Calculations can be performed on historical as well as ongoing batches in real-time.

Qubicon model calculation

Mathematical models can be further used to control the process (e.g. feed-on-demand). A Wizard guides the user through a straightforward process planning module, including the intuitive mapping of scripting-variables to process sensors.

Qubicon two chart view

The Charts module visualizes multiple data sets, such as on-line, off-line historical- or live values, as well as calculated data within one chart using up to five different y-axes. A navigator below each chart allows for easy orientation and quick navigation through the whole process in zoom mode. In addition, various view modes facilitate and speed up the visualization and inspection of all data.

Further functionalities

All actions within Qubicon® are tracked and linked to the operator through identification and authentication upon login. User access rights can be defined by the system administrator by assignment to pre-defined user groups.

The Status module gives a quick overview of the whole system environment including all equipment connected to Qubicon and their actual status information.

The multi-client access allows several users to operate on the software simultaneously without interrupting each other.

Qubicon® is constantly being improved and additional new functionalities are currently in the planning process, such as an improved workflow for design of experiment (DoE) execution as well as the integrated control of continuous manufacturing setups.


The state-of-the-art for process control and quality assurance in biopharmaceutical manufacturing is based on a static Quality by Testing approach. The production process is fixed and tightly specified to guarantee a constant and defined product quality, which is verified by intensive testing. Exceeding the specification ranges of such processes results in rejection of batches and consequently leads to increased consumption of raw material and energy. In 2002 the US Food and Drug Administration started the Process Analytical Technology (PAT) initiative, aiming to guide the industry towards more dynamic manufacturing processes. PAT is focusing on the identification of Critical Process Parameters affecting the product’s Critical Quality Attributes and subsequently their real-time monitoring and control.

However, these quality attributes are usually not directly measurable. The proposed strategy to be followed is to employ complex on-line analyzer systems (f.i. 2D fluorescence spectroscopy or Raman spectroscopy) in combination with mathematical techniques to build up correlations between nonspecific signals and process variables for real-time estimation of process performance and product quality.

The main hurdle of this approach is the implementation of advanced sensor systems, delivering hundreds or thousands of values at each measurement, to the Process Control System. This includes data storage, pre-processing and data alignment in a GMP conform manner.
