You got the answer right!
Water can be found in each laboratory type, be it medical, pharmaceutical, chemistry, and microbiological.
These laboratories need different levels of water purity for the different levels of sensitivity of their analysis and experiments. The whole water purification process is long and involves many steps. For example, activated carbon -known as adsorption media and works effectively removing chlorine in water by a catalytic mechanism and dissolved organics by adsorption. Storage of distilled water is also important to keep it from contamination. Of course, reverse osmosis -Osmosis is the movement of water from higher concentration to lower concentration as caused by the osmotic pressure. Loads of us know that there are still impurities found in distilled water just like silica, ammonia, and similar organic compounds.
In reverse osmosis, water is passed through a filter using a higher pressure than the osmotic pressure to separate the impurities.
Distillation -Water is heated and the condensed vapor is trapped and collected.
Ion exchange -This process removes various metals particularly heavy metals present in water however ion exchange will retain microorganisms. However, ultraviolet disinfection -It uses ultraviolet light which is a powerful sterilizing agent to kill bacteria and similar microorganisms. There are also different kinds of water types in consonance with their use in the laboratory. Type This is the ultrapure water which has very low levels of ions, organic molecules, bacteria, and particles. It is used for analytical methods just like highpressure liquid chromatography, gas chromatography, and inductivelycoupled plasma mass spectrometry.
It is commonly manufactured by combining purification technologies similar to activated carbon, reverse osmosis, ion exchange resins, ultraviolet photo oxidation, filtration processes, and electrodeionization. Type This send water type is known as pure water and may contain a minute quantity of ions, organic molecules, and possibly a small percentage of microorganisms. Contrary to popular belief, tap water can not be used for just about anything in the lab because of the impurities found in it. Notice, for the most part there’re different kinds of water types corresponding to the different needs of a laboratory.
