Unlike conductivity, resistivity is primarily used in the assessment of ultrapure water. As such, it also provides a measure of the water's ionic content. Reported as Mega-Ohms per centimeter (MO-cm) at 25oC, resistivity is related to conductivity: a high resistivity equals a low conductivity. Conductivity is typically used when assessing water ranging from 'raw water' through to 'drinking water' and provides a valuable, non-specific indication of the level of ions in the water. The Conductivity of WaterĬonductivity is reported as microSiemens per centimeter (µS/cm) at 25oC and is the reciprocal of resistivity and provides a measure of a fluid's ability to conduct electrical current. To implement a coherent classification system for water purity, we make use of several key factors describing the various properties of water. How is Laboratory Water Purity Assessed and Defined? It can also be used as a feed water for Type I water production. Of all the pure water types it has the lowest level of purity, but is typically the starting point for basic lab applications, such as cleaning glassware, heating baths or media preparation. Type III grade water, also known as RO water, is water produced through the purification technology reverse osmosis. It can also be used as feed water for Type I water production. Microbiological Analysis and preparation.It can also be used in applications such as: It is a good feed water for clinical analyzers as the calcium build-up is reduced with this water type. Type II water grade doesn’t have the same pureness of Type I, but still maintains high levels of purity. This is quite a common practice that can help to avoid the generation of by-products during applications. Type I can also be used in applications that require Type II water. Inductively Coupled Plasma Mass Spectrometry (ICP-MS).Liquid Chromatography, including High Performance Liquid Chromatography (HPLC).It’s used for the most critical applications and advanced analytical procedures. Type I grade water, also known as Ultrapure Water, is the purest form of water to be produced. (c) ELGA LabWater 2020 Type 1 Water (Ultrapure Water) Diagram showing the different types of water used in the lab: ultrapure water, pure water and primary grade water. Knowing this informs the purification technology you use and systems you require to produce the right water grade.Īs we’ve said, there are several different types of water, however at ELGA we specialise in the production of three types in particular: Type I, Type II and Type III. Making the decision on which type of pure water you need for your application can be challenging. This includes a range from Type III for general use such as rinsing out your beakers, all the way up to Type I+ for sensitive applications like the intriguingly sounding ‘graphite furnace atomic absorption spectrometry’ (GF-AAS).
