Quantification of mathematical statements is done using quantifiers such as "for all" (∀) and "there exists" (∃). The symbol ∀ is used to indicate that a statement is true for all elements in a set, while the symbol ∃ is used to indicate that there exists at least one element in a set for which the statement is true. These quantifiers help to make precise and formal statements about mathematical properties and relationships. By using quantifiers, mathematicians can express universal and existential statements in a clear and unambiguous way. **

The detection limit is the lowest concentration of a substance that can be reliably detected but not necessarily quantified. It is typically defined as the concentration at which the signal is distinguishable from the background noise. The limit of quantification, on the other hand, is the lowest concentration of a substance that can be accurately measured and quantified with a known level of certainty. It is usually higher than the detection limit and is determined by the precision and accuracy of the analytical method being used. **
