What is Ultra Pure Water?
Ultrapure water is a high quality grade of water widely used in engineering applications and laboratory testing. Although it is produced in a similar way to deionised and demineralised water, ultra pure water retains some features that make it distinct from these products.
Popular uses of ultrapure water include:
- Research and testing in a range of laboratory environments
- Cleaning medical and healthcare equipment
- Diagnostic clinical analysis and testing
- Production of semiconductors.
Producing and Testing Ultrapure Water
As quality-assured chemical manufacturers, our ultra pure water is produced using a system that starts with an organic trap to remove any organic matter. This is followed by a twin-bed deioniser to remove cat ions and an ions, along with a mixed-bed resin to further reduce contaminants.
The resulting water is of an extremely high standard which we know as deionised or demineralised water. This then undergoes further testing to a higher specification, before being sold as ultrapure water.
Owing to customer demand, ReAgent now tests its ultrapure water to a higher specification than our deionised and demineralised water. Testing for ultrapure water now includes:
- Conductivity testing to less than 0.05 microsiemens when packed
- Chloride testing to less than 1 ppm
- pH testing
- Total chlorine testing
- Free thlorine testing
- Nitrate testing
- Nitrite testing.
Ultrapure Water vs. Deionised Water: What’s the Difference?
Many customers often ask about the differences between ultrapure and deionized water. Not only is ultrapure water tested to a higher standard than deionised and distilled water, it has also gone through a much more rigorous filtration process.
Ultrapure water has usually gone 12 filtration steps beyond reverse osmosis, with the final filter having pores just 20 nanometers wide. While deionised water is often the water of choice for lubricating and cleaning industrial machines and the production of cosmetics and medicines, ultrapure water is usually more preferable in the production of electronics and for precise chemical testing. Some deionised water is also safe to drink, whereas ultra pure water is not.
