What is the difference between hydrogen conductivity and normal conductivity?

This is a concept in high-purity water analysis; the same type of conductivity meter is used for this purpose. However, when measuring hydrogen conductivity, a cation exchange resin column is placed at the sample inlet to convert the cations in the sample into hydrogen ions, thereby increasing the sensitivity of the detection. This type of measurement is generally carried out using an online method, which requires minimal sample processing, namely a conversion device. HACH and DKK can both be used.

I don’t understand; I’m just taking up a seat to study**

I need a detailed explanation. GB12145-2008 specifies the hydrogen conductivity; what would be the value for ordinary conductivity?

I don’t understand either; come and learn*, please give me some guidance

The definition of conductance is the reciprocal of resistance, and its unit is μS, which is the reciprocal of MΩ. Specific conductance is the same as conductivity; it is defined as the conductance between two electrodes of 1 cm×1 cm with a distance of 1 cm between them. This value is referred to as conductivity or specific conductance, and its unit is μS/cm. The water samples used for measurement were actual, untreated samples. Hydrogen conductivity and cation conductivity are the same; it is the conductivity measured of water that has first been passed through a hydrogen ion exchange column, and its unit is also μS/cm. However, it should be specified whether it is hydrogen conductivity or cation conductivity. Hydrogen conductivity essentially involves passing the water sample through an ion exchange column to eliminate the influence of ammonia ions, thereby providing a more accurate reflection of the concentration of harmful anions in the water
