Introduction to Particle Counting

Introduction to Particle Counting Particle counting may be performed using two different techniques, each with its own limitations and interferences, but one aspect they share in common is that they are both only a quantitative count. Neither method identifies the composition or source of the particles, they only provide a level of particles per ml…

Oil Analysis Trending vs. Alarm Limits

Oil Analysis Trending vs. Alarm Limits Many static alarm limits are based on statistical analysis of a common grouping of machines under similar operating conditions. As long as machine is operated under similar conditions (load, speed, temperature, ambient environment) for a similar sampling and drain interval, the limits may have merit.

Sources of Potassium

Sources of Potassium Potassium is an indicator of a coolant leak, often in conjunction with sodium and/or boron; these elements are present due to the additives used in many coolant formulations. The presence of these elements alongside detected glycol and water often indicate a severe or bottom-end leak, but the absence of glycol and water…

Sources of Lithium

Sources of Lithium Lithium is used in the most common form of a thickener system for greases. Generally, trace levels of grease migrating into a lubrication system are not harmful; however, the additives from the grease may create a negative synergy with the additives in the lubricant. Watch for the next article in the Elemental…

Sources of Boron

Sources of Boron Boron is an additive metal commonly used in detergent additives and occurs in some EP or AW additive chemistries. Only when the boron level deviates more than 25% from the new oil or reference value should a concern be raised, but the likeliest cause is mixing or topping-off with a different product.…
