ALS Tribology receives regular inquiries regarding problems with prematurely plugged fuel filters. Inquiries have originated from both users of conventional middle distillate fuel and from those using biodiesel blends. The majority of these fuel filters were heavily contaminated with a black substance. Analysis of this black substance revealed that the predominant contamination species noted was carbon particulate.  Read More

The following report and picture is from a reduction gear used in a mining application. The time on the component was 3860 hours, and time on the oil was 300 hours. Sample frequency is every 1 – 2 months.  Read More

With waste reduction, sampling ease of use, and logistics efficiency in mind, ALS has added a 20 mL option to the PFAS in water container set (along with revised container considerations for Super-Trace and Super Ultra-Trace PFAS methodologies). Read More

The measurement of total arsenic concentrations is generally adequate for environmental compliance monitoring, but knowledge of discrete inorganic and organic arsenic species concentrations is crucial to understanding true toxicity and health risks to humans and aquatic or terrestrial organisms. Humans are exposed to arsenic in many ways, including occupational exposure (e.g. smelting, mining), drinking water, and food sources, but the toxicity of different arsenic species and sources varies greatly.

Even though an engine coolant system is an integral component for engine health, 20 times more engine oil samples are tested than coolant samples. Cooling system problems are related to a significant number of engine health issues. Read More

Hydraulic fluid viscosity is critical to optimizing pump and system efficiency. There is a narrower viscosity range where power losses are minimized and power transfer is maximized. The greater the viscosity of a fluid, the more energy that is required to move the fluid regardless of workload.  Read More

Selenium (Se) is an essential nutrient for humans and many microorganisms, as a component of selenoproteins such as selenocysteine (the 21st amino acid) and selenomethionine. The recommended dietary allowance for selenium is 55 μg/day, but excessive levels can cause human health problems (selenosis). Read More
