Not only was Abraham Lincoln the 16th President of the United States of America, but he was also a patent attorney and a patent holder. Lincoln holds US patent #6,469 "Buoying Vessels Over Shoals". This patent describes a method of increasing the buoyancy of vessels through the use of inflatable bladders to guide them over, or free them from shoals or shallow waters.
The most important physical property of a lubricating oil is viscosity. It determines the load carrying ability of the oil as well as how easily it circulates. The correct balance between high viscosity for load carrying and low viscosity for ease of circulation must be considered for any lubricant and its application. Oil provides benefits in addition to lubrication, and it is vital that it be able to flow under all conditions. When in use, contaminants such as water, fuel entering the oil, oxidation, and soot all affect the viscosity. Therefore viscosity measurement is one of the more important tests for oil in a mechanical system. For machine condition monitoring, kinematic viscosity, defined as the resistance to flow under gravity, is the established method.
Monitoring TAN and TBN is an important test for measuring lubricant condition. There
are several methods available ranging from expensive laboratory methods to quick field
tests. In a laboratory setting, methods are chosen based on the highest accuracy and
repeatability that can be achieved with a decent throughput. Out in the field, it is most
important to get a trustworthy result quickly enough that preventative or corrective
maintenance action can be taken before major equipment failure. The best method to
use depends on the application need.
Compressor oils can create unique challenges when trying to measure viscosity. Dissolved gases from refrigerants, in particular, tend to bubble out when these oils are measured using traditional viscometers. This can create errors in the measurement, typically causing readings to be much lower than they should be.

Certain types of samples, such as those containing detergent, may form emulsions when doing an oil in water extraction into a solvent. The boundary between the solvent and the sample will have an emulsion layer that has a cloudy or milky appearance as shown in this photo.
1. It takes a lot of specialized instrumentation
The days of needing a laboratory full of specialized equipment to do oil analysis are long gone. The MicoLab® all-in-one oil analyzer combines four separate analytical instruments into one compact device. The MicroLab is used to test for elemental analysis, viscosity, oil chemistry and particle contamination. It only requires a small amount of space and is designed to be operated in non-lab environments, like garages, so it is easy to incorporate into your existing work space.
MicroLab is a “lab in a box”
