Virtually every laboratory has equipment for measuring a physical property, and this equipment requires regular calibration against certified standards
LGC Promochem, a supplier of certified reference materials, launches an extended range of physical properties standards. Researchers, analysts and quality control technicians in all sectors of industry and science measure physical properties.
The measurements complement those of chemical properties in identifying and characterising substances, providing an indication of the purity of a substance or identifying impurities.
Virtually every laboratory has equipment for measuring a physical property, even if it is just a pH meter or a melting point apparatus and, to ensure the accuracy, traceability and repeatability of these measurements, this equipment requires regular calibration against certified standards.
To meet this requirement, LGC Promochem has produced Reference materials for physical properties, its first catalogue devoted purely to physical standards.
Physical standards cover a wide range of properties, from viscosity to infrared absorption and from density to optical rotation.
The applications for these standards are even more diverse, spanning industries from pharmaceutical manufacturing to automobile production, oil refining to food, as well as areas such as healthcare, environmental protection, forensic science and clinical research.
The reference materials are catalogued according to the type of physical property being measured which, in most cases, is related to the type of energy involved, including electricity, heat, light and sound.
For example, there are standards for optical properties such as light absorbency or transmittance, which are used to calibrate spectrometers.
Other categories include thermal standards for melting point or flash point, standards for properties of particles such as surface area, shape and size, and amperometric and potentiometric standards concerned with pH, redox, ion activity and conductivity.
The products listed in LGC Promochem's new catalogue include reference materials and standards from commercial sources, as well as from national and international bodies, and each product is accompanied by a certificate of analysis containing details of the values associated with the material and other information about the product.
The catalogue, which has been designed to be simple to use, provides a brief description of each product together with details of the relevant parameters from the certificate of analysis.
LGC Promochem says it offers the widest range of certified reference substances available from a single source in Europe.
LGC Promochem sources its products from the world's leading reference material manufacturers to ensure that they meet the exacting needs of customers.
LGC Promochem's distribution network across Europe and India, combined with its experience in reference materials distribution, means the company can provide faster delivery, local technical support and assistance with import requirements.
Analysts can access LGC Promochem's wide range of products, including Reference materials for physical properties, via its interactive website, which offers an advanced search facility and online ordering to account holders for over 11,000 reference materials in English, French or German.
