Gauges. This is a word that is incorrectly used by many people to describe the jewelry worn in stretched earlobe piercings. The Gauge system is actually a system of measurement, initially created to measure the thickness of wire and other cylindrical objects.
What is calibration and what is its importance? Calibration is defined as an association between measurements â one of a scale or accuracy made or set with one piece of equipment and another measurement made in as similar a way as possible with a second piece of equipment.
A calibration curve is one approach to the problem of instrument calibration; other standard approaches may mix the standard into the unknown, giving an internal standard. The calibration curve is a plot of how the instrumental response, the so-called analytical signal, changes with the concentration of the analyte (the substance to be measured). The operator prepares a series of standards across a range of concentrations near the expected concentration of analyte in the unknown.
