CAS touch! - Charge Analyzing System

The new CAS touch! Charge Analyzing System combines proven methods of particle charge measurement with the known great simplicity of handling and functioning of the previous CAS versions, but enhanced with new features and an immense reduction in weight and size.

Basics:

Using standard techniques of titration, the CAS touch! determines cationic/anionic and acid/base demands of aqueous charge systems. Modern electronic components enable the high accuracy of measurement. Both, Streaming Potential (mV) and pH can be measured simultaneously, making it possible to easily determine isoelectric and flocculation points of a sample and examine the correlation between pH, titrant demand and streaming potential.

Customer’s choice:

The CAS touch! uses integrated high precision titrators, optionally with 1 or 2 titration systems (CAS-I touch!, CAS-II touch!), while also a version for use with external or hand titration is available to the customer (CAS-E touch!).

Measurement / Result evaluation:

The CAS touch! can be operated via Touch Screen, which displays the data including titration curves, optionally in combination with an external keyboard. Moreover, there is no need to adjust to a new software, as the device can also be used with the common easy-to-handle CAS PC software. The efficient testing procedures implemented in extremely user-friendly PC software make it very easy to handle. Different titration procedures are available: fixed increment titration, dynamic titration and back-titration are selectable from given procedures or are freely configurable. Default standard titration procedures and customer-specific processes can be stored in the CAS touch! via the PC software or Touch Screen. Data can be stored internally as well as externally on an USB flash drive, analyzed with PC software and exported to Excel (only two mouse clicks).

Transport / Assembly:

The low weight device can easily be transported in a carry-on size case, which is especially important for chemical suppliers for customer visits.
After unpacking the device and connecting it to the mains voltage, the CAS touch! is ready for starting the measurement! There is no complicated assembly and no tubes are needed.

Features:

Smaller and significantly lighter than comparable devices
-> Comfortable transport (carry-on luggage size)
Latest state-of-the-art Touch Screen with display of results and curves
External keyboard connectable (USB or wireless)

Features:

The new FPA touch! Fiber Potential Analyzer combines proven methods of Zeta Potential measurement with the known great simplicity of handling and functioning of the previous FPA versions, but enhanced with new features and an immense reduction in weight and size.

Surface charges of fibers, fillers, particles or colloidally dissolved substances in stock suspension are defined by the Zeta Potential on their surfaces. The charge of the stock suspension can be split into the colloidal and particle charge, measured with the CAS touch! Charge Analyzing System, while the fiber and filler charge is measured with the FPA touch! Fiber Potential Analyzer. All both charge levels together define the overall Zeta Potential of fiber suspensions.

The knowledge of the fiber charges in the pulp is the key for optimized dosage of chemical aids, which should be adsorbed onto the surface of the fiber. The mostly negatively (anionic) charged fiber is adsorbing the positive (cationic) charged additives in the papermaking process. The optimized dosage of such aids always depends on the Zeta Potential within the pulp.

The FPA touch! is designed to determine the Zeta Potential of fibers according to the Helmholtz-Smoluchowski equation by simultaneously measuring conductivity, pressure and the streaming current potential. The measuring principle is based on the streaming current potential measuring method in a fiber plug. That fiber plug is automatically building up on a screen electrode in the measuring cell of the FPA by a vacuum. By periodically changing the vacuum during the measurement the charge clouds absorbed on the fibers are moving with the liquid stream and generating the streaming current potential measured by the screen and ring electrode.

The knowledge of the fiber charge enables a correct and effective dosage of the charged chemical additives. The fiber adsorption of cationic starch, wet strength resin, and many other chemical aids can be easily measured with original samples on-site to optimize the dosage of chemicals in the wet end of the paper manufacturing process.

  • No external connection cable for electrodes - thereby prevention of handling errors
  • Display of measuring results on touch screen or via high-performance PC Software with display of trends
  • Storage of data on internal data memory of the device, USB flash drive or on the PC when connecting PC software
  • All components at latest technological standard

CAS - Charge Analyzing System

 

casThe CAS particle charge measurement system takes traditional methods of measuring Streaming Potential and established a new era of technology and comfort in particle charge analysis. Using industry accepted techniques of titration CAS determines cationic/anionic and acid/base demands of aqueous charge systems. Both Streaming Potential (mV) and pH are measured simultaneous.
Making it possible to easily determine isoelectric and flocculation points of a
sample.

How the CAS differs from conventional charge detectors is its integrated
titrator and the use of a modern and user-friendly PC software. No longer is it necessary to have separate devices – Charge Detector, pH Meter, Thermometer, Titrator – to conduct charge analysis. The CAS brings it all together in one simple to use portable package. The instrument comes with a highly accurate computer-controlled dosing pump. Expensive external titrators are no longer necessary. The integrated titrator also eliminates the need for hand titrations, saves time and increases accuracy. Essential in busy labs and situations where the consumption rate is very low.

The user-friendly and powerful PC-software allows for easy handling and transfer of test results. Data can be stored, analysed, exported to Excel or e-mailed from one platform. The CAS system comes with a temperature compensated pH-detector. This feature allows determination of the isoelectric point (IEP), but also the examination of the correlation between pH, Titrant Demand and Streaming Potential.
