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.

Positive material identification or PMI is the act of confirming a type of metal alloy based on its chemical composition. This methodology is used in a wide range of applications where the specific chemical composition or grade of the alloy is critical and specific for its end use. PMI is used most commonly in industrial settings where use of the wrong metal alloy grade can result in premature corrosion or even failure of a structure, creating a potentially serious safety hazard. The chemical verification of alloys already in use in various industrial applications often requires that the analysis be non -destructive and performed insitu. The analysis is most commonly performed using a handheld XRF unit often called a "PMI gun" or with a portable Spark-OES instrument.
- Is your instrument optimized?
In a recent blog we explored the importance of instrument optimization for ICP-OES and ICP-MS, but all instruments should be frequently checked to confirm they are operating as expected. Preventive maintenance and appropriate start up and shut down SOPs are key to the integrity of analysis.
