Scientific experiments are fundamental to the exploration and validation of scientific theories. As experimental techniques advance, laboratory instruments have become increasingly sophisticated. Correspondingly, the purity standards for reagents and water used in testing processes have risen. In most experiments, the water environment serves as a critical foundational setting, where high-standard water quality not only ensures the precision of results but also reduces material consumption and avoids time-consuming repetitive analysis. Thus, the quality of water is crucial for scientific research experiments.

Classification of Laboratory Pure Water and Application of Ultra-Pure Water

In scientific experiments, pure water levels are selected based on the required precision. Laboratories typically use four levels of pure water: pure water, deionized water, Type II pure water, and ultra-pure water.

Ultra-pure water, also referred to as Highly Purified Water (HPW), represents the highest purity level of laboratory water. Its extremely low impurity content minimizes interference in experimental results, ensuring accuracy, reliability, and reproducibility. Hence, maintaining the high quality of ultra-pure water is vital for precision analysis experiments.

The key indicators in assessing the quality of ultra-pure water include resistivity, Total Organic Carbon (TOC) content, and endotoxin levels. These not only determine the water's application scope but are also crucial for measuring its precision.

To meet these stringent quality standards, ultra-pure water preparation involves various purification technologies. Significantly, the ultra-pure water preparation industry highly favors ultraviolet photo-oxidation for its efficiency in degrading TOC and effective water disinfection and disinfection.

GMY Laboratory Ultra-Pure Water TOC Degradation and Disinfection Solutions

For many years, the ultra-pure water preparation equipment industry has relied on imported core light sources. In response, GMY, with its over 20 years of experience in R&D and manufacturing in the field of lighting technology, has been committed to innovating supply chain solutions. GMY offers more tailored and cost-effective lighting application solutions for the laboratory ultra-pure water preparation industry, addressing the long-standing reliance on imports for core lighting components.

01.185nm+254nm Laboratory Ultra-Pure Water TOC Degradation and Disinfection Equipment

GMY's ultra-pure water TOC degradation and disinfection equipment, as a core component of advanced ultra-pure water systems, uses high-dose ultraviolet light technology at 254nm and 185nm wavelengths, achieving dual-effect disinfection and efficient TOC degradation.

  • 254nm Ultraviolet Light: Utilizes 254nm wavelength UV light to disinfect bacteria, viruses, and other microorganisms in water, preventing bacterial growth and inhibiting microbial proliferation.

  • 185nm Ultraviolet Light: Decomposes water molecules with 185nm wavelength UV light, producing hydroxyl radicals (OH·) and hydrogen radicals. These radicals further oxidize the water's hydrocarbons, transforming them into carbon dioxide and water, thus achieving ppb-level TOC degradation and enhancing water purity to ultra-pure standards.


02. 172nm Ultra-Pure Water Preparation

Furthermore, to fulfill the strict requirements of ultra-pure water preparation, GMY also provides advanced mercury-free ultraviolet technology—172nm excimer lamp ultra-pure water treatment. This innovative technology radiates higher-energy 172nm UV light for more efficient and faster TOC degradation, meeting higher standards in organic pollutant removal for ultra-pure water equipment.


Application Fields

This equipment system finds application not only in laboratory ultra-pure water preparation but also in the electronic industry and pharmaceutical sector, among other fields.
