Biosensors

At The Gwent Group we provide a range of one-shot disposable biosensors for the agri-food and environmental analysis

Ammonia Sensors- AE2071122D6

A biosensor suitable for electrochemical measurements of ammonia in aqueous solutions. The combination of Glutamate Dehydrogenase and NADH drop coated onto the sensor gives a response to ammonia in water solutions in the range 1 to 10ppm. Ammonia measurement in sewage water is the typical test done using this type of biosensor. N.B. Product is not available at the moment. It is undergoing further development work. We do apologise for the inconvenience.


Pyruvate Sensors

A biosensor suitable for electrochemical measurements of pyruvate in onion samples. The combination of Lactate Dehydrogenase and NADH drop coated on to the sensor gives a response to pyruvate in onion solutions in the range 1 to 10mM. A pyruvate measurement for onion pungency is the typical test done using this biosensor.


Cholesterol Sensor - AE2140110D2

A biosensor electrode ideal for electrochemical measurements of cholesterol in aqueous samples. These biosensors are coated with Cholesterol Oxidase and Cholesterol Esterase that are fully soluble upon immersion in the test solution and will give a response to cholesterol in solutions prepared with 0.1% Triton X-100 solution. The biosensor can be used for measuring concentrations between 0-0.4mM.


Lactate Sensor - AE2131129D2

A biosensor electrode ideal for electrochemical measurements of lactate in aqueous samples. These electrodes are biosensors are coated with Lactate Oxidase and peroxidase that are fully soluble upon immersion in the test solution and will give a response to lactate in aqueous solutions. The biosensor can be used for measuring concentrations between 0.04-0.5mM.


Glucose Sensor - AE2140725D2

A biosensor ideal for electrochemical measurements of glucose in food samples. The biosensor uses Glucose Oxidase and an electrochemical mediator to measure glucose concentration in aqueous solutions. The biosensor can be used for measuring concentrations in the range 1 to 30 mM glucose.


All our biosensors can be supplied in batches of several hundreds
