Calcium (Ca2+) ion-selective electrode for 300 seriesThe new electrode is suitable for the LAQUA WQ-300 series from Horiba and offers precise and reliable measurements for ions in aqueous solutions. It is characterised by its user-friendly handling and environmentally friendly design and can be used for a wide range of applications.Linearity in measurement range:The range where the calibration curve has linearity is called the measurement range. When lower concentration is measured where the linearity is not established, perform calibration at two points in the lower concentration range.Below graph shows the theoretical calibration curve of a calcium ion selective electrode.Influence of pH:The impact of the pH may cause a decrease in the slope of the ion selective electrode, or parallel shifting of the calibration curve. To prevent these effects, set the pH to an appropriate value in advance and keep it constant.Interfering ions:Ion selective electrodes have good selectivity with respect to the ions to be measured, but they may react to the other ions. When using the ion electrode method, it is important to know the effects of coexistent ions and take measures to avoid them. Interfering ions may form compounds with poor solubility or may form complex salts with the structure material of the ion selective membrane, these may to have a significant impact on the measured value.Conditioning:An electrode is conditioned by soaking it in a standard solution for 1 hour or longer. Use a standard solution whose concentration is 100 mg/L or more.In the following cases, perform conditioning of the electrode before calibration.• Before the first use.• Before use after storage for 2 weeks or longer.• If the electrode is less responsive.Calibration:Always calibrate with at least 2 calibration solutions which are 1 decade apart and bracket the expected measurement value.Use fresh calibration solutions and do not re-use them.• Below 10 ppm (mg/L)First solution between 1 and 10ppmSecond solution between 10 and 50 ppm• Between 10 and 100 ppm (mg/L)First solution between 10 and 100ppmSecond solution between 100 and 1000 ppm• Above 100 ppm (mg/L)First solution between 100 and 1000ppmFurther information can be found in the download area of the store.

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.
