Essential water quality for COVID-19 testing

Essential water quality for COVID-19 testing

COVID-19 or novel coronavirus is wildly spreading across the world and its outbreak has set alarm bells ringing globally. Effective diagnostic methods are crucial to the early diagnosis, prevention and control of the pandemic, such as nucleic acid detection and antigen-antibody detection. At present, nucleic acid test plays a critical role in the diagnosis of an active COVID-19 infection, especially

Which grade of water to use for Silver Staining

Silver staining is used to detect proteins after electrophoretic separation on polyacrylamide gels. Among the various protein detection methods, the technique of silver staining has gained wide popularity because of its higher sensitivity (in the low ng range) than that of Coomassie blue. Meanwhile, it can be achieved with simple and inexpensive laboratory reagents and no complicated and expensive hardware for the

Standards Set by USP on TOC Test

TOC, short for (Total Organic Carbon), is the total amount of carbon in water dissolved and suspended organics. There are many kinds of organics in water, and different organic compounds have different carbon content. TOC is often used as one of the most important composite parameters in the assessment of water quality and an indirect measure, as carbon, of organic molecules

Water Quality Standards

International Organization for Standardization specification for water for laboratory use ISO 3696: 1995This standard covers three grades of water as follows:Grade 1 Essentially free from dissolved or colloidal ionic and organic contaminants. It is suitable for the most stringent analytical requirements including those of high performance liquid chromatography (HPLC). It should be produced by further treatment of grade 2 water for

UV Irradiation Method

UV IrradiationUV Irradiation is another technology which can be applied to water purification for Bacteria & Organics. These technology uses high intensity ultra-violet radiation to destroy bacteria and other micro-organisms and to cleave and ionize any organic compounds for subsequent removal by ion exchange cartridges. Radiation with a wavelength of 254 nm has the greatest bactericidal action, while radiation at

Reverse Osmosis (RO) Method

Reverse Osmosis (RO) Method

Reverse osmosisReverse osmosis (RO) is a process that overcomes many of the shortcomings of distillation and ion exchange. To explain reverse osmosis let us first look at osmosis. This is a natural process, which occurs whenever a dilute solution is separated from a concentrated solution by a semi-permeable membrane. Water, driven by a force caused by the concentration difference –

Ion Exchange Method

Ion ExchangeIon exchange is widely used in laboratories for providing purified water on demand. Laboratory deionizers invariably incorporate mixed-bed cartridges of ion exchange resins that are either returned to a regeneration station for recharging when they become exhausted, or else discarded. Anions and cations in the feed water are removed by the ion exchange resins and are replaced by hydrogen
