How do I maintain my ammonia electrode?

The tip of the electrode should be rinsed with deionised water between measurements. To maintain electrode health strongly acidic samples, strong detergents or organic solvents should be avoided. To take a reading ammonia electrodes require the end cap to be filled with ammonium chloride solution. This solution should be removed after each usage, so that… Continue reading How do I maintain my ammonia electrode?

Testing Dissolved Oxygen in Wine

Dissolved oxygen in wine can be beneficial to some varieties in small amounts, but otherwise is known for reducing the quality and lifetime of the wine. It is therefore important to be able to measure and control dissolved oxygen throughout the production and bottling stages. Flint Vineyard measure both pH and dissolved oxygen throughout their… Continue reading Testing Dissolved Oxygen in Wine

How can I improve the performance of my crystalline ion selective electrode (ISE)?

How can I improve the performance of my crystalline ion selective electrode (ISE)?

Crystalline ion selective electrodes (ISEs), such as the TRUEscience chloride, bromide and copper, tend to develop an oxidised layer on the crystal sensing tip after a period of time. This may lead to the electrode having a slower response.   To improve performance first make sure the cyrstal surface is dry, then use a very fine… Continue reading How can I improve the performance of my crystalline ion selective electrode (ISE)?

Will temperature effect my Ion Selective Electrode (ISE) measurements?

Will temperature effect my Ion Selective Electrode (ISE) measurements?

The answer is yes, temperature is an important factor when making any type of electrochemistry measurement. A rise in temperature of a solution will increase the kinetic energy and accelerate the speed of which the ions move around. This will higher the chance the ion you are measuring will hit the sensing tip of the… Continue reading Will temperature effect my Ion Selective Electrode (ISE) measurements?

How to refill your Ammonia detecting Electrode

How do I refill my Ammonia Cap? When using an ammonia detecting electrode caring for your electrode is essential in order to extend your equipment’s lifetime. Your electrode should ideally be emptied of solution after every use and stored dry to prevent degeneration and when the electrode is needed it needs to be refilled again.… Continue reading How to refill your Ammonia detecting Electrode

How does an Ammonia Ion Selective Electrode (ISE) work?

The TRUEscience Ammonia ion selective electrode is made up of three parts: a flat surface PH electrode, a Teflon membrane located in the end cap and a refillable ammonium chloride solution. The Teflon membrane is partially permeable and allows gas to pass through. This means that ammonia gas can pass through the membrane and react… Continue reading How does an Ammonia Ion Selective Electrode (ISE) work?

Top Tips for dissolved oxygen measurements

As with all electrodes maintenance is key to keeping your readings stable and accurate. The TRUEscience Dissolved Oxygen probe is a galvanic sensor with a fixed membrane cap. This galvanic probe provides good performance without the problem of membrane replacement associated with polorgraphic electrodes. It offers good sensitivity and response but the sample must be stirred during readings. Take care… Continue reading Top Tips for dissolved oxygen measurements
