The LoQ is the limit at which the difference between two distinct signals / values can be discerned with a reasonable certainty, i.e., when the signal is statistically different from the background. The LoQ may be drastically different between laboratories, so another detection limit is commonly used that is referred to as the Practical ...
Of course, +/- the MDL is probably too generous even if the result is slightly above the LOQ, but the problems with the relationship between the MDL and the claimed uncertainty will normally continue well above the LOQ. For example, a hypothetical method has an MDL of 1ppm, a claimed uncertainty of +/-10%, and an LOQ of 5ppm. I get a result of ...
A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

The NFL's six wild-card games feature some potentially entertaining affairs – and maybe a few duds along the way to boot.
Social Security is the U.S. government's biggest program; as of June 30, 2024, about 67.9 million people, or one in five Americans, collected Social Security benefits. This year, we're seeing a...

Sweeping deportations pledged by President-elect Donald Trump could pose an economic shock for the restaurant industry in ways that echo the pandemic: pricier menus, rising wages, and shuttered ...
The difference between MDL and MML is a source of ongoing confusion. Superficially, the methods appear mostly equivalent, but there are some significant differences, especially in interpretation: MML is a fully subjective Bayesian approach: it starts from the idea that one represents one's beliefs about the data-generating process in the form ...
