Ultra pure water machines play a very important role in liquid chromatography. Before analyzing samples, liquid chromatography usually requires the use of high-purity solvents and water to prepare the solution, which is used to wash the chromatographic column and pre-treat the sample. The ultra pure water machine provides high-purity water, ensuring the accuracy and reliability of experimental results.

The following are several key roles of ultrapure water machines in liquid chromatography:

1. Preparation of solvents: The solvents used in liquid chromatography usually require high-purity organic solvents and water. The ultra pure water machine can provide high-quality solvents to remove ions, impurities, and organic substances from the water, ensuring the purity and stability of the solvent, and avoiding contamination of the chromatographic column and sample.

2. Preparation of mobile phase: A liquid chromatograph uses the mobile phase to separate the components in the sample. Ultra pure water machines provide high-purity water for the preparation of various types of mobile phases, such as gradient solvents and buffer solutions. High purity water can reduce background noise and impurity peaks, improve signal strength and separation efficiency.

3. Washing chromatographic column: The chromatographic column is the core component of liquid chromatography separation and requires regular washing and regeneration. The high-purity water provided by the ultrapure water machine can be used for washing the chromatographic column, removing residual samples and impurities, and maintaining the performance and lifespan of the chromatographic column.

4. Sample preparation: In liquid chromatography analysis, samples usually require pre-treatment and preparation. The ultrapure water machine provides high-purity water for sample dissolution, dilution, and washing, ensuring the purity and accuracy of the sample.

The ultra pure water machine provides a reliable and high-purity water source for liquid chromatography, ensuring the accuracy and repeatability of experimental results. High quality water can not only improve the sensitivity and resolution of analysis, but also extend the service life of chromatographic columns and instruments, providing a good foundation for scientific research and analytical experiments.
