An Introduction to Viscometers

Viscometers are instruments that measure the fluid flow and viscosity of liquids. The viscosity of a liquid can affect its performance, whether this is pumping or piping it, or how it performs for dipping and coating. Measuring viscosity, therefore, applies to a wide range of materials, including: Oil Plastics Paints Coatings Adhesives Wax Asphalt Measuring viscosity and flow properties also applies to the production of familiar consumer items such as food and drink, toothpaste, cosmetics and shampoo. View Viscometers from Scimed What Does a Viscometer Do? Viscometers measure the viscosity and flow properties of liquids, and have a wide variety…

What is ICP-MS?

Atomic spectroscopy is the technique for determining the elemental composition of an analyte by its electromagnetic or mass spectrum. Several atomic spectroscopy analytical techniques are available and selecting the most appropriate one is the key to achieving accurate, reliable, real-world results. This article focuses on ICP-MS. Overview An inductively coupled plasma mass spectrometer is an analytical tool capable of measuring very low levels of about 72 different elements. Most of these elements have limits of detection below the part-per-trillion range with some even in the parts-per-quadrillion range. Samples are introduced into an argon plasma as an aerosol. The plasma dries…

What is Flash Point Testing?

Flash point testing is a procedure designed to determine whether a sampled mixture of vapour and air is flammable. It can also determine the temperature at which flammability occurs in a sample. The lowest temperature at which its vapours ignite from an ignition source is the flash point of a material. Flash point analysis is important for testing various products, including lubricants and petroleum-based materials. The oil industry uses flash point testing for oil analysis. View Flash Point Testing Equipment from Scimed Why is Testing for Flammability Important? Process industries routinely use flammable materials. This exposes them to frequent risk…

What is a Hydrogen Generator?

H-Genie Hydrogen Generator FAQ   What is a Hydrogen Generator? A Hydrogen generator is a machine that is used to produce hydrogen from water, using a process called electrolysis. If the supply pressure of hydrogen from the generator is high enough, it can eliminate the need for hydrogen cylinders by providing a safer and more user friendly alternative alternative. How does a hydrogen generator work? A hydrogen generator works by using electricity to split the hydrogen atoms in a water molecule apart form the oxygen atom. This is done by a process called electrolysis, and is performed in a cell…
