Imacimus K-VI

The K-Vi analysis system allows the direct measurement of the exact concentration of potassium, this giving rise to rapid analysis and greater reliability. K-Vi is based on the selective electrode potentiometric technique, simple and effective, capable of performing analysis in a few seconds simply with a quick calibration, such as pH measurement.

Equipment for simultaneous analysis of process water, waste water, hydroponics systems, algae reactors, and anywhere automatic information

about ionic sample composition is needed.

Up to 7 ions simultaneously: Ca2+,Cl-,K+,Na+,NH4+, NO3-/pH Up to 4 sample intake.

Direct measurement: Not sample pre-treatment necessary, not interfered by sample colour or turbidity.

Readings are obtained through multi ion probe configured with specific modular ion selective electrodes. This method provides a wide measurement range (see specifications table for each ion) and allows eliminating cross interferences using combinations of electrodes.

The equipment is built on an IP66 box to be placed in or outside.
Sample intake configured according sampling point (atmospheric pressure or positive pressure) Auto diagnose functions are ready to inform users.

The simplicity of the measurement

The measurement of potassium in wine samples with K-Vi is a simple process, which basically can be summed up in 3 steps:

  1. Preparation of the sample Wine aliquot (5 ml) is taken and is made 1/4.
  2. Electrode calibration 2-point sensor calibration is calibrated, following the software instructions.

3. Measures The probe was inserted into the sample and in 1 minute the result. You can perform multiple measurements with a single calibration

The Potassium in wine

Wine contains different dissolved salts, especially salts of potassium, calcium, iron and copper, among others. These elements may give rise to instability phenomena, but the most important is due to potassium cation. It is capable of forming a bond with tartaric acid to form potassium bitartrate. Upon reaching a predetermined concentration of potassium bitartrate may precipitate, which leads to a decrease of the total acidity and a slight increase of the pH of wine. Tartaric stability of wine remains one of the major problems that can affect your marketing. The consumer demand can taste wines that are biologically and chemically stable. For this reason, it is essential to monitor the level of potassium in the wine, so know the levels bitartrate and avoid unwanted precipitation.

Potassium content analysis

The most commonly used for controlling the precipitation such as potassium bitartrate and its technique is the measurement of the electrical conductivity. This technique measures the total ion content in an aqueous sample, not be able to distinguish each type of ion, leading to low reliability measures. Analysis system K-Vi allows direct measurement of the exact amount of potassium, thereby resulting in a faster and more reliable analysis. The K-Vi system is based on selective electrode potentiometric technique, simple and efficient, capable of performing analysis in just a few seconds with a quick calibration and pH measurement technique.
