By now you may have heard the exciting news that Paragon Scientific (Paragon) has joined the LGC Standards family, and has joined forces with VHG, ARMI, and MBH to create LGC Industrial.
What does Paragon specialize in? Revered as a trusted partner in European markets, Paragon specializes in the production of premium quality reference materials including Density, Flash Point, Refractive Index, and Viscosity standards. We are excited to bring these products to the global markets.
Signed in 2016, The Paris Climate Agreement aims to usher in a carbon-neutral society by 2050. Greenhouse gas emissions released from vehicles play a significant role in achieving the overarching goal of the agreement.
Copper is a versatile metal used for a wide variety of applications. The alloying elements that are combined in Cu provide properties, such as strength, electrical conductivity/resistivity, ductility, luster, and even anti-microbial qualities, that are very desirable for the end user. Verification of the composition of the final alloys is critical to ensuring the material will be fit for use.
Flash point is the lowest temperature at which a liquid (usually a petroleum product) will form a vapor in the air near its surface that will “flash,” or briefly ignite, on exposure to an open flame1. Back in the late 1800s, flash point was a lived experience. Households primarily used kerosene for heat and light, and open flame was a part of every day. Bad kerosene – fuel diluted with gasoline or other contaminants – delivered unpredictable flash points and bad results. Fires and explosions were fairly common. These shared catastrophes ushered in a focused effort to establish meaningful standards for various grades of petroleum. Both ASTM2 and OSHA3 have created standard flash point measurement methods that are used today.
If you asked Canadian petroleum chemist J.S. Charlesworth in 1947 what the most important characteristic of lubricating oil was, he would have said, Viscosity1. After all, he said, “it’s a measure of the oil’s resistance to flow, or of its internal friction…[i]t indicates…the ability of an oil to support loads.” At just about the mid-20th century, the American Society of Testing and Materials (ASTM) published a set of standards for the measurement of viscosity of petroleum products2. Of course, the importance of viscosity is well known today, and there are standard methods worldwide to ensure uniformity of testing.
We are pleased to announce that we have added a complete range of physical reference materials to our product portfolio through our recent acquisition of Paragon Scientific. The Paragon portfolio compliments the elemental analysis products we currently offer under our VHG, ARMI and MBH Industrial sector brands and provides a more complete offering to our customers.
Our team has been hard at work and we are excited to add five new copper CRMs to our product portfolio. Copper can be alloyed with a wide range of elements enabling highly specific functions and applications. The large compositional range of copper alloys means that high-quality, matrix-matched reference materials are needed for proper analysis of each alloy.
Sulfur is nearly always found in petroleum products and feedstocks.1 It is usually removed during crude oil processing as it is considered an undesirable contaminant that leads to the formation of harmful pollutants such as sulfur oxides.
