What is laboratory water purification systems?
Water is the most commonly used solvent in laboratories. It is used for cleaning and is the basis for cell cultures, buffers, and reagents, making water quality critical to experiment success.
Although tap water is generally considered to be relatively pure, there are five types of contaminants that may pose a problem for laboratory tasks.
Inorganic ions, organics, particulates/colloids, bacteria, and gases are all included.
For technical and economic reasons, water grades (Types 1–3) aid in defining different levels of water quality. This assists the user in determining the best water quality for a given application. The technologies used to remove contaminants determine water quality.
Contamination in the laboratory pure water impairs process performance!
The purity of the water used in clinical and research laboratories has always been critical to the integrity of the results. However, advances in scientific instrumentation have meant that even minor differences in water quality can now make a significant difference. The sensitivity of instrumentation has evolved over time in an effort to improve data accuracy and precision. As a result, contamination in the laboratory pure water will not only impair process performance but will also increase the signal-to-noise ratio and lower detection sensitivity. Water quality and impurities are thought to be responsible for 70% of problems with high-performance liquid chromatography (HPLC) processes.
When it comes to selecting pure & ultra-pure water, there are some common misconceptions!
The purity level (Type I, Type II, Type III, etc.) for example, only indicates the purity of the water used to fill the containers. The conditions under which the water is stored, the manner in which it is used, and the material, all have an impact on its purity at the point of use. Purified water is commonly delivered in plastic bottles, which, if not manufactured and handled correctly, can contaminate the water with organic plasticizers, molding release agents, solvents, and monomers – especially if stored for an extended period of time.
Furthermore, once the bottle is opened, the purity starts to deteriorate. When water is removed, air is drawn in, introducing bacterial, ionic, and organic contaminants. To reduce the degree of degradation, the Clinical and Laboratory Standards Institute (CLSI) recommends that labs only purchase bottled water in small quantities that can be used quickly. This is especially important for Ultra-Pure water (Type I), which, due to its extremely low resistivity levels, may become unacceptably contaminated as soon as the container is opened, and so care should be taken when storing it for later use.
An in-house purification system can provide an on-demand supply of water with the required level of purity as an alternative to bottled water!
This is frequently more cost effective, especially in the long run. Even when the system's total life cost is considered, which includes the initial investment, lab purification system consumables, and maintenance, very low costs per litre of water can be achieved. These systems also help to reduce the organization's environmental impact by eliminating waste.
There are a variety of systems available to meet almost any laboratory or pure water supply requirement. A purification system can also provide water purification flexibility as the lab's needs change over time.
Among the purification technologies used are-
· Reverse osmosis (RO).
· The exchange of ions (IX).
· Electro-deionization (EDI).
· UV (ultraviolet) light.
· Filtration to the extreme.
