In order to convert the mass concentration to an equivalent concentration the following mathematical relationship is used:

For example, a water with a calcium concentration of 120 mg/L would have the following calcium equivalent concentration:

These observations have been confirmed in rats, where the accumulation was found to be 12.5-fold with absolute, equivalent concentrations exceeding 90 μM (Table 3).

Our finding also confirms previous reports that postprandial serum gastrin consists of approximately equivalent concentrations of G17 and G34.

By standard convention, Stiff diagrams are created by plotting the equivalent concentration of the cations to the left of the center axis and anions to the right.

It loads faster, is brighter at equivalent concentrations and is well-excited by the 488 nm line of the argon-ion laser which is often used in biological research laboratories.

However, in human post-mortem cases, mefloquine has been found to accumulate in the brain relative to plasma by as much as 30-fold, with absolute, equivalent concentrations exceeding 50 μM (Table 3).

Whether equivalent concentrations of relevant molecules can be achieved in the bloodstream of individuals who consume Essiac or Flor Essence in the amounts recommended by their manufacturers has not been determined.

Bicarbonate ions only contribute half as much carbonate hardness as carbonate ions, so bicarbonates that are present in the water are converted to an equivalent concentration of carbonates when determining KH.

The human equivalent dose (HED) or human equivalent concentration (HEC) is the quantity of a chemical that, when administered to humans, produces an effect equal to that produced in test animals by a smaller dose.

Chlorine in water is over three times more effective as a disinfectant against Escherichia coli than an equivalent concentration of bromine, and over six times more effective than an equivalent concentration of iodine.

The EIA kit is designed for the screening of samples according to their toxic equivalent concentration (TEQ) by responding to the toxic PCDD/F congeners in approximate correlation with their toxic equivalency factors (TEFs).

PMD can be synthetically manufactured; however, studies have found that repellents containing synthetic PMD mixtures are not as effective as those containing naturally derived PMD where the PMD content is in equivalent concentrations.
