Electrical Conductivity Test

What Is Electrical Conductivity?

When voltage is applied to both ends of a conductor, electrons in the conductor exhibit the behavior of flowing in a certain direction, creating an electric current.

Electrical conductivity is a parameter used to describe the ease with which a charge flows through a substance per unit length and unit area. It is represented by the Greek letter σ. The standard unit for electrical conductivity, σ, is siemens per metre (S/m).

Why Measure Electrical Conductivity?

• Material identification - Electrochemical conductivity is a fundamental property of materials, and different substances have varying electrical conductivities. By measuring the electrical conductivity of a material, we conduct qualitative testing of substances.
• Quality Control - During the production process, conducting electrical conductivity tests on products can quickly detect potential deterioration that may arise in production, ensuring product quality.
• Environmental monitoring - In environmental monitoring, electrical conductivity tests can be used to assess the level of water pollution. For example, the amount of dissolved salts in water affects its electrical conductivity. By measuring the electrical conductivity of water, we can indirectly determine the salt content in the water.
• Drug Development - Electrical conductivity testing can be used to measure the electrical potential, conduction speed, and ion channel activity of isolated organ tissues, nerves, and cells. This is important for studying drug mechanisms and developing new drugs.

How to Measure Electrical Conductivity?

The instrument used to test electrical conductivity is a conductivity meter, which places two parallel electrodes in the solution to be tested (or specialized probes for solid samples), applying a certain potential difference across the electrodes and then measuring the current flowing between the electrodes.

Service Process

Initial Consultation & Project Planning

We first engage with clients for an initial consultation to ascertain their unique needs.

Our service begins with an initial consultation where we gather crucial information about the sample. This includes understanding the sample's appearance, whether it's a liquid or solid, which is essential for selecting the appropriate testing method.

Our team of experts then designs a comprehensive project plan. This plan covers the test method, instrument selection, testing conditions, and the proposed timeline. It is shared with the client to ensure transparency and alignment with their specific requirements.

Sample Preparation & Testing

Upon receiving the sample, our laboratory professionals carefully handle and prepare it for analysis.

For electrical conductivity testing, this may include cleaning the surface of solid samples or, for those with irregular shapes or complex structures, additional preparation to obtain an appropriate sample that can be used for testing.

We use state-of-the-art conductivity meters to conduct the tests.

Data Analysis & Reporting

Our experienced analysts conduct electrical conductivity tests and gather all relevant data, ensuring precision and accuracy. We then provide clients with a final report that includes the electrical conductivity measurement data, details of the testing conditions, and experimental steps.

Follow-up Support & Consultation

After the submission of the final report, we stay in contact with our clients, ready to answer questions, address concerns, and provide additional guidance.
