“To restore the gleam, use a microfiber towel dampened with a mixture of lemon juice and olive oil. Clean the surface in a circular motion, then rinse thoroughly with clean water. The olive oil ...
Gemstone refractometers are available both as classic optical instruments and as electronic measurement devices with a digital display. [3] In marine aquarium keeping, a refractometer is used to measure the salinity and specific gravity of the water. In the automobile industry, a refractometer is used to measure the coolant concentration.
Refractometers are frequently used by grape growers and kiwifruit growers for Brix testing of sucrose levels in their fruit. Refractometry is also used in the gelatin industry. To convert the RI of a gelatin sol (reported in Brix) to a gelatin concentration, one need only multiply by eight-tenths (0.8). A sol with a 10.0 RI would therefore be 8 ...
Extra virgin olive oil can go bad a little sooner, after around 12 to 18 months. To know how long your olive oil has been sealed, the most important date to look for on the bottle is the harvest date.
Digital handheld refractometers are generally more precise than traditional handheld refractometers, but less precise than most benchtop refractometers. They also may require a slightly larger amount of sample to read from since the sample is not spread thinly against the prism.
This process can be used to study, for instance, the growth of a thin film, [8] including calcium phosphate mineralization at the air-liquid interface, [9] etching or cleaning of a sample. By in situ ellipsometry measurements it is possible to determine fundamental process parameters, such as, growth or etch rates, variation of optical ...
Olive oil contains small amounts of free fatty acids (meaning not attached to other fatty acids in the form of a triglyceride). Free acidity is an important parameter that defines the quality of olive oil. It is usually expressed as a percentage of oleic acid (the main fatty acid present in olive oil
In the Abbe refractometer the liquid sample is sandwiched into a thin layer between an illuminating prism and a refracting prism. The refracting prism is made of a glass with a high refractive index (e.g., 1.75) and the refractometer is designed to be used with samples having a refractive index smaller than that of the refracting prism.
