Issues with the preparation of laboratory water
Thread Content
What are the advantages and disadvantages of each method for producing laboratory water—distillation, ion exchange, and electrodialysis? Which one is better?
Each has its own advantages and disadvantages; two commonly used types are distilled water machines and deionized water. Choose according to your actual situation.
Thank you both. I see. But are they all of first-class quality?
The poster can refer to \"GB 6682-92 Specifications and Test Methods for Water Used in Analytical Laboratories.\" As for which type of water to choose, it depends on what is convenient for you; grade 3 water from a regular laboratory will suffice. But in companies like ours, which have power plants, it is very convenient to use secondary water as a substitute for tertiary water, which can be used normally.
