Ion-sensing membranes directly cover the field-effect transistor’s gate region in ISFETs, which are potentiometric sensors (FET).
ISFET and glass electrodes (440-M4, Ingold, Switzerland) both exhibit a linear response over the pH range of 1.3 to 8.0, and in vitro tests have demonstrated that their reaction times and 24-hour drift are comparable.
A pH sensor, which has a range of 0 to 14, aids in determining the water’s acidity or alkalinity. Water begins to turn more acidic as the pH value falls below seven.
Any value over seven indicates a higher alkaline level. Different pH sensors operate in different ways to gauge the water’s quality.
Enzyme-based ISFET applications. On the idea of pH-sensitive ISFETs, which states that the concentration of hydrogen ions during an enzymatic reaction is proportional to the level of substrate, enzyme FETs are generally based.
Ion concentrations in solutions are measured using ion-sensitive field-effect transistors (ISFETs). As the ion concentration (such as H+, see pH scale) varies, the current through the transistor will also change.
By monitoring the activity of the hydrogen ions in the sample fluids, Campbell Scientific pH sensors determine the pH level.
Using a pH scale from 0 to 14, the activity compares the sample solutions to pure water (a neutral solution) to determine if they are more acidic or alkaline.
The Global ISFET pH Sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Endress+Hauser introduces the Memosens CPS47D, CPS77D, and CPS97D ISFET pH sensors for applications where glass pH sensors provide a breakage risk in difficult process conditions.
ISFET sensors are available with three different reference systems and are composed of unbreakable PEEK, offering a glass-free pH sensor to meet every need.
The CPS47D and CPS77D SFET Memosens sensors are designed to withstand the rigours of sanitary applications. These sensors are simple to clean because of their updated design and larger chip surface. They are TSE/BSE-free and provide stable and repeatable measured results even after being autoclaved and sterilised up to 275 °F (135 °C) in temperature.
They also have the standard sanitary certifications for the food and life sciences industries, including USP, EHEDG, and 3A.
They have a CIP stability that is far better than traditional ISFET sensors, lasting at least 25 CIP cycles. Additionally, the Memosens CPS77D’s microporous ceramic diaphragm provides optimal microbial tightness.
pH measurement is particularly difficult in chemical processes that occur at low temperatures or in which a significant amount of organic solvents or solids are present.
The Memosens CPS97D has a quick response time even at low temperatures and is chemically stable because of its PEEK stem.
Additionally, even in situations with high solids concentrations, its open diaphragm remains unobstructed. The referenced hard gel is very chemically resistant as well.
Memosens technology allows digital ISFET sensors to retain calibration, sensor, and process data. Combining the Liquiline platform with effective sensor management utilising Memosens Plus software would significantly boost process safety. The sensors can be cleaned and calibrated under ideal circumstances in a lab using Memobase Plus software.
In addition to extending the sensors’ useful lives, this also makes commissioning and maintenance much simpler and minimises process downtime. Additionally, predictive maintenance and process optimization can be done with the saved data.
