The SENTEK Flow Plus range incorporates two solid state ISE’s in one 12mm epoxy body. One acts as the sensor whilst the other is incorporated into the system. All Flow Plus Electrodes have the following advantages:
· Solid State Sensor · Unlimited Shelf Life · Variable Flow Reference System for Greater Stability · Rounded Solid State Reference ISE for Smooth Electrolyte Delivery · Liquid Junction Provide Rapid Response · Adjustable Electrolyte Flow for Awkward Applications · Construction Allows Easy Cleaning of Components
|
|
Principal of Operations: The SENTEK solid state sensor provides rapid analysis as it does not require pre-conditioning or an internal solution. Its shelf life is also longer than that of standard ISE’s. The Flow Plus reference system has a liquid junction provided by a conical plug which is opened or closed by rotation of the electrode cap. The wider the gap between the plug and the epoxy the faster the flow of electrolyte from the electrode liquid junction. The electrolyte passes over a rounded, polished solid state ISE incorporated into the electrodes inner shaft. The internal ISE varies in type according to the ion being used as the sensor. The electrolyte and the internal ISE therefore always have the same potential and contact is made between the two ISE’s by the following electrolyte. Flow Plus Combination ISE’s have several technical advantages over conventional combination electrodes. These are clearly demonstrated upon use of the electrodes in real situations with awkward samples or in cases where stability, response times, or drift cause a problem.
