Physical testing and chemical analysis services from MISTRAS give insight into material composition to determine performance.
MISTRAS labs offer physical chemical analysis solutions to give insight into the composition and make-up of materials. Our solutions help to determine material the physical composition of substances on a macroscopic level, giving insight into how materials behave and react under particular factors and in intense environments.
Optical emission spectrometry (OES) applies a small spark to a material with an electrical discharge, causing a small amount to be vaporized. MISTRAS' lab testing experts are then able to study the elemental breakdown of the material to determine the quantitative composition of the metal.
Corrosion Testing encompasses the analysis of a material’s resistance to corrosion and the affect corrosion has on a material. These tests accurately determine how certain components will operate in real-world conditions where the formation of corrosion and erosion is very likely.
Material analysis includes several test methods to determine chemical, physical, and mechanical properties of materials. These test methods include inductively coupled plasma (ICP) spectrometry, spark optical emission spectrometry (OES), inert gas fusion, combustion analysis, and many more. Material analysis services from MISTRAS are designed to qualitatively and quantitatively reveal the elements in a material sample. Material analysis services are primarily offered as metallographic procedures, which involve the study of the metal microstructure. Metallographic procedures include sectioning, cutting, grinding, polishing, etching, analysis, hardness testing, and more. Metallographic procedures helps to predict the end of the product’s lifecycle and ensure safety.
The properties of specific coatings and paints that are used in componentry and materials are tested to ensure that they are effective throughout the product lifecycle. There are various types of paint coating tests that include adhesion, resistance to liquids, thickness, and mechanical strength testing. Paint and coating tests are an essential part of physical testing and chemical analysis, ensuring that components are finished properly for efficiency while in commercial uses.
Titration, also referred to as volumetric analysis, is a technique where the amount of a specific dissolved substance is measured. A complete chemical reaction of the substance (analyte) with a reagent (titrant) added to the solution is required. Various types of titration with either visual or potentiometric end point detection are used to determine the concentration of products used for different kinds of surface treatment processes such as degreasing, etching and anodizing.
Ion chromatography is a versatile test method for ionic and polar species. Depending on the respective separation task various columns (stationary phase) are used with specific solvents, acids, bases, or mixtures of the aforementioned (mobile phase). The mobile phase transports the ions through the stationary phase where they are separated via adsorption and desorption processes, depending on their individual charge. Ion Chromatography is commonly used across industries as it is a reliable test method. It is a rapid, sensitive, selective, and accurate test method that is able to simultaneously quantify different ions.
