APSS – AutomaticParticleScanSystem
The AutomaticParticleScanSystem (APSS) refers to an entire product family of our robotic solutions for automated filter integrity testing. The product family consists of RobotScanFlex (RSF), which scans cleanroom ceilings and walls, HEPA/ ULPA filters, laminar flow units, terminal S-filters, vertical flow workstations, and safety cabinets. Furthermore, it is possible to scan filter units within sterilization tunnels using LinearTwinScan (LTS). The integratedRobotScanFlex (iRSF) is used within isolators and RABS systems. All three robot systems include the two subsystems CBOX and RGM as well as a tablet with the ScanWare and ScanWorx software packages installed.
The subsystems that make up the respective robot system are supplied in separate storage boxes or bags for easier handling during transportation and storage. The tablet is stored in the transport box of the ControlBox (CBOX). The HPRC hard cases are equipped with castors and can therefore be moved easily. The transport case of the stand can be carried on the shoulder using the handholds. Only one certifier is required to load and transport the system. Assembly can also be carried out by a single person, whereby the system remains mobile when assembled.
The subsystems from our APSS robot family are taken out of the transport boxes before being transferred to a cleanroom. All subsystems are also packaged in textile sleeves. The textile inner packaging stays closed during the entire infeed process. The prerequisite for this is that the contents have been disinfected in accordance with the cleanroom regulations, packaged in a clean environment and are then not opened again. The inner packaging as well as all hoses and cables are disinfected and transferred as prescribed by the cleanroom operator.
For easier handling, the CBOX and RGM sleeves are equipped with grip pockets, while the three storage sleeves for the robotic arm, the linear module, and the stand are fitted with a carrying strap for easier transportation. The system can be disinfected both with the textile inner packaging and when assembled. This means that it is possible to insert the system without a cover.
CBOX
The ControlBox (CBOX) is the central component of the system and forms the interface between all electrical, electronic, and mechanical units of the system. It contains the PLC, which controls the entire system. All subsystems are connected to the CBOX via mechanical or electronic interfaces. An integrated Wifi router ensures a connection between all subsystems for communication and data transfer. The CBOX also has a USB port which can be used to store the data collected during the measurement on a system-compatible USB stick so that a report can be created in just a few simple steps once the measurement is complete. The CBOX can be moved on castors for easier handling in the cleanroom.
RGM
The RawGasModule (RGM) is used to generate and monitor the DEHS test aerosol which is applied upstream of the filter element. The aerosol generator integrated into the RGM generates a test aerosol from liquid DEHS, which is then fed into the filter system via hose connections. The RGM is equipped with a particle counter and vacuum pump to continuously measure and monitor the upstream challenge concentration. These results are used to determine the particle limit values of the filter to be measured. The aerosol concentration is automatically controlled by the RGM and can be monitored and adjusted using the ScanWare software. The RGM can be moved on castors for easier handling in the cleanroom.

ScanWare
The ScanWare software package is used to control and monitor the robotic solutions for filter integrity tests and collect all measurement data. ScanWare is operated via the system’s own tablet.
The measurement is initialized and the robot is moved to the start position using the respective touchpad. During the measurement, the status of the measurement can be traced and the results can be observed in real time as a heatmap.

ScanWorx
The ScanWorx software package is used to prepare the measurements in PreProcessing and to evaluate and log them in PostProcessing. All necessary data is recorded on a USB stick.
Once a measurement has been completed, the data collected during a measurement is summarized in a digital measurement log. In addition to the clearly listed measurement results, the 2D heatmap, and the used equipment, this report also contains all the necessary certificates.
Tablet
The robot systems are controlled using a tablet to set up and start the measurements. It can also be used to view the results live and monitor the measurement. Finally, a digital measurement report with all the necessary data is created via the tablet with just a few taps and in the shortest time possible.
