The palltronic AquaWIT IV system is delivered ready-to-use.To get started, an electrical connection and a stable source of pressurized air of at least 4.5 bar (58 psi) must be supplied.The system can be connected to a water source to fill the onboard 18 L (4.5 gallon) water tank.

Water Source and Filling

Water Intrusion Tests are normally performed with de-ionized (DI) water, or water of comparable quality.The removable water tank of the palltronic AquaWIT IV system can either be filled manually or automatically.The system can recognize if the water level is too low or that the tank is full, and can close the water supply.If an appropriate water supply is permanently connected to the system, the system is also capable of refilling the water automatically.

Fully Automated Water Intrusion Testing

The palltronic AquaWIT IV system can also perform a complete Water Intrusion Test fully automatically.Once the filter housing is connected to the system and the relevant test parameters are programmed, the system can control up to three pneumatic valves around the filter housing in order to isolate the filter from the process, fill the housing with water, perform the integrity test and drain the housing after the completed test.The test result can then be printed, or saved as an electronic record.

Fully Automated Forward Flow and Bubble Point Test

The Auto Test Time function is available for the Forward Flow Test and the Water Intrusion Test in order to shorten test times while maintaining the reliability of the result.Results of Forward Flow or Water Intrusion Tests are interpreted by this algorithm during the test.If the measured flow rate is evidently below the test limit and the measurement is stable, the system will interpret this as a passed test.Filter integrity test times can be reduced by over 50%, without any risk of false pass results.

Auto Test Time

The Auto Test Time function is available for the Forward Flow Test and the Water Intrusion Test in order to shorten test times while maintaining the reliability of the result.Results of Forward Flow or Water Intrusion Tests are interpreted by this algorithm during the test.Again if the measured flow rate is evidently below the test limit, and the measurement is stable, the system will interpret this as a passed test.Filter integrity test times can be reduced by over 50%, without any risk of false pass results.

Electronic Records and Signatures (21 CFR Part 11)

The palltronic AquaWIT IV system has been designed to be used in an environment subject to the regulations of 21 CFR Part 11 for the storage of electronic records and signatures.The system presents three levels of access – Operator, Supervisor or Administrator.Operators have access to the test functions only, supervisors can modify test programs in addition, but only administrators have full access to all functions, also performing changes to the system configuration or access management.The system can also be used in two different modes to limit access to the protected functions.When the password-controlled access function is activated, supervisor and administrator levels are each protected by a password.In the login-controlled access mode, each user must log in to the instrument with an individual user name and password before having access to its functions.The level of access can be defined for each person separately.All the changes performed on the system or the programs are recorded for audit purposes.For increased flexibility, test results can be electronically signed, and configuration, test programs, user data and test results easily and quickly exported to a network or external USB drive.

External Connections

A number of connections at the side of the palltronic AquaWIT IV system allow interaction with external control systems.The USB port can be used to connect USB devices such as a printer, barcode reader or flash drive, and the Field Bus port allows connection to a process PLC (Programmable Logic Controller).The Ethernet (LAN) port or onboard wireless network adapter can be used to link the system to an external network, and an additional port for an external pressure sensor is provided.

Remote Operation

The palltronic AquaWIT IV system can be quickly and simply connected to a remote PLC, thanks to its onboard internal adaptors.The PLC can fully control the system, with adapters available for all common communication protocols.The instrument can also be fully controlled via a Supervisory Control And Data Acquisition (SCADA) system by simply connecting it to the OPC UA server that is running on the system.

Remote Printing

As an alternative to use of the integrated printer, print data can be exported to an external printer, either networked or connected via USB.Print data can easily be exported electronically in a variety of standard formats including PDF or XML.

Controlling Critical Test Parameters

With several factors potentially having an adverse effect on the Water Intrusion Test result, some (e.g. water quality) can be easily controlled and need not be monitored by the test system.Others, like potential contamination of the filter with a low surface tension liquid, need to be controlled in the processing system.The palltronic AquaWIT system controls the remaining parameters and assures meaningful, reproducible results.

Water and Environmental Temperature

The temperature of the test water directly influences the water evaporation rate through the hydrophobic filter membrane.If the test water is much colder than the water used for filter validation, the flow rate will be lower than in the validated system.This needs to be avoided, as it could lead to a false positive result.The palltronic AquaWIT IV system checks the temperature of the water before the test and will display a warning if it drops below 18 °C.While the water temperature can directly influence the test conditions, environmental temperature will have an influence on the measurement conditions.All instruments that use a gas flow measurement to determine the flow rate require that the gas temperature is stable and within validated limits for the duration of the test.In a pharmaceutical process, this cannot always be assured – air conditioning outlets or steam lines close to the filter housing could potentially change the temperature during the test.The palltronic AquaWIT IV system transfers the gas measurement into a better-controlled, internal environment, minimizing the affect of environmental factors.

Controlled Filling

The filter system must be filled with water in order to perform a Water Intrusion Test, but test results can be affected if air is trapped in unwanted places in the filter system during filling.However, the palltronic AquaWIT IV system can control the filling pressure, enabling a very controlled filling step and eliminating the risk of trapped air.

Flow Measurement

Very small flow rates must be measured accurately in a Water Intrusion Test.As a water flow rate is measured, the upstream gas volume changes over the course of the test.The palltronic Flowstar IV instrument inside the palltronic AquaWIT IV system uses a special volume-dosing flow measurement technology.This unique measurement principle was developed by 颇尔 to improve the accuracy and reproducibility of the filter integrity test relative to other test instruments, eliminating the need to validate system-specific correction factors.

Self Test

The palltronic AquaWIT IV system will automatically run an internal Self Test once per day when it is switched on.This Self Test can also be initiated manually by a user at any time.During the Self Test the instrument carries out a full check of its functions:
  • Inlet gas pressure
  • Function of the internal valves
  • Function and signal of the internal pressure sensors
  • Function of the internal pressure regulator
  • Check for internal leaks
  • Internal communication
  • Integrity of the operating system and its software
  • Data integrity of user lists, test programs and test results
The full result of each Self Test is saved and can be printed at any time.The combination of the self test along with a regular calibration and preventive maintenance program can help to assure continuous, reliable operation of the system.

Increasing Process Safety

Even if the critical test parameters are well controlled, there is still a small risk of filter integrity test failure.The palltronic Flowstar instrument can detect inconsistencies and reduce the risk of false positive test results.

Fault Detection

In some cases, pneumatic conditions for a successful test are not met.These may be caused by leaks in the test system or an unstable pressure source.The palltronic AquaWIT IV system can identify such conditions and prompts the user by providing specific screen messages on where to locate the problem.

Low Flow Rate

In a Forward Flow Test, the gas diffusion rate is measured across a wetted filter membrane, along with any bulk flow through open pores, and in the Water Intrusion Test a water evaporation rate through a hydrophobic membrane is measured, along with any bulk water flow.With integral filters, both values must have a certain amount, and cannot be zero.'Zero' or 'Undetectable Flow' indicates an invalid test.The palltronic AquaWIT IV system compares the measured flow rate to an expected minimal flow rate.If this measure is lower than the expected minimal flow, the instrument will terminate the test and notify the user.

Downstream Pressure Sensor

In certain cases, the volume downstream of the filter cannot be as large as required.If so, there is a risk that the pressure on the downstream side could rise during the test so that differential pressure over the filter membrane cannot be maintained.As a consequence the measured flow rate could decrease, increasing the risk of a false pass result.The palltronic AquaWIT IV system can help to avoid this, as a pressure sensor can be installed downstream of the filter and connected.If the downstream pressure should rise above a specified value, the test is aborted and the user notified.
