Liquid Measurement

Technology for measuring the components and properties of liquids, such as pH, electrical conductivity, and chemical concentration

HORIBA provides measurement instruments for monitoring the concentration of chemicals used in semiconductor manufacturing processes, controlling the purity of ultrapure water essential for cleaning, and for wastewater treatment. From the production of increasingly high-performance semiconductors to wastewater treatment to protect the environment, HORIBA supports semiconductor manufacturing process and facility with our cutting-edge measurement technologies.

Absorption Spectroscopy

A method of detecting concentration by measuring how much light is absorbed as it passes through a sample.

Potentiometry (Glass Electrode Method)

A method of determining pH by measuring the potential in a solution.

Potentiometry (Ion Electrode Method)

A method that determines the ion concentration by measuring the ions in a solution.

Electrical Conductivity Method

A method that involves placing electrodes in a solution to determine the ease (or difficulty) of electricity flow.

Polarographic Method

A method also known as Diaphragm Electrode Method or Diaphragm Galvanic Electrode Method involves applying a voltage to the electrodes and determining the concentration of the target component by measuring the magnitude of the current, which varies depending on the components of the solution.

Light Transmission Method

A method that involves passing light through a solution and determining the concentration of the target component based on the degree to which the light is absorbed.
