Liquid-In-Glass Thermometers. A liquid-in-glass thermometer is the simplest and most commonly employed type of temperature measurement device. It is one of the oldest thermometers available in the industry. It gives fairly accurate results within the temperature range of -200 to 600Â°C. No special means are needed to measure temperature via these thermometers.
This brings us to the definition of detection or reporting limits. The smallest concentration (or amount) of analyte, that can be reported by a laboratory is called reporting limit. AIHA requires RL (reporting limit) which is LOD times a safety factor selected by the laboratory.
Limit of Detection (LOD) or detection limit, is the lowest concentration level that can be. determined to be statistically different from a blank (99% confidence). The LOD is typically. determined to be in the region where the signal to noise ratio is greater than 5.
