Horiba 9600-10D PUREIL pH electrode for measuring low conductivity water and solutions that react with KCl

The Horiba 9600-10D PUREIL pH electrode can perform pH measurements in water within five minutes without affecting its conductivity thanks to its gel ion liquid salt bridge. This pH electrode allows pH values in water with low conductivity to be measured accurately and quickly.

An innovative pH electrode that does not release KCl

Accurate readings through quick and easy measurement

This pH electrode is used to determine pH values in water in order to reliably determine pH values. It supports measurements in the pH range 0-14 and is ideal for water with low conductivity (<100 µS/cm) such as ultrapure water samples (e.g., distilled water, rainwater, reverse osmosis water, and boiler water).

KCl is usually diffused in pH electrodes, but the use of a newly developed ionic liquid salt bridge now makes it possible to stabilize the potential difference at the liquid interface.

When measuring with the 9600-10D PUREIL pH electrode, no potassium chloride is released that could influence the measurement or the pH value in samples with low ionic strength or special solutions.

Advantages:

• Maintenance-free and waterproof
• Built-in temperature sensor for automatic temperature compensation
• Minimal dissolution of the ionic liquid during the measurement process
• Precise and fast measurement even with samples with low electrical conductivity
• The impact on the sample is a maximum of 1/10,000 compared to conventional methods
• Measurements are also possible with samples that react with KCl
• Waterproof construction

Suitable for:

Can be used for water with low electrical conductivity (pure water, rainwater, river water) and medical solutions (injections).

Solutions that react with KCl (potassium chloride) or contain ions, such as injection solutions.

Not suitable for:

Since the Pure IL pH electrode uses an ionic liquid as a salt bridge as a reference electrode, it is not suitable for measuring samples containing surfactants, heavy metal ions, or organic solvents.

For acidic samples, citrate buffer (pH 3.776 at 25 °C) is recommended for calibration instead of phthalate buffer (pH 4.01 at 25 °C) in order to achieve a more accurate measurement.

Why should I use this electrode?

The 9600-10D PUREIL is a very good and stable pH electrode. If you value speed and accuracy, this electrode is the right choice.
