  2. Dilution ratio - Wikipedia

    en.wikipedia.org/wiki/Dilution_ratio

    Dilution factor is a notation often used in commercial assays. For example, in solution with a 1/5 dilution factor (which may be abbreviated as x5 dilution ), entails combining 1 unit volume of solute (the material to be diluted) with (approximately) 4 unit volumes of the solvent to give 5 units of total volume.

  3. Dilution (equation) - Wikipedia

    en.wikipedia.org/wiki/Dilution_(equation)

    Dilution is the process of decreasing the concentration of a solute in a solution, ... where the ventilation rate has been adjusted by a mixing factor K: ...

  4. Serial dilution - Wikipedia

    en.wikipedia.org/wiki/Serial_dilution

    A serial dilution is the step-wise dilution of a substance in solution, either by using a constant dilution factor, or by using a variable factor between dilutions. If the dilution factor at each step is constant, this results in a geometric progression of the concentration in a logarithmic fashion. A ten-fold serial dilution could be 1 M, 0.1 ...

  5. Titer - Wikipedia

    en.wikipedia.org/wiki/Titer

    The titer corresponds to the highest dilution factor that still yields a positive reading. [2] For example, positive readings in the first 8 serial, twofold dilutions translate into a titer of 1:256 (i.e., 2 −8). Titres are sometimes expressed by the denominator only, for example 1:256 is written 256. [3]

  6. Solution (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Solution_(chemistry)

    Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.

  7. Standard addition - Wikipedia

    en.wikipedia.org/wiki/Standard_addition

    The dilution factor is multiplied by this initial concentration to determine the original concentration. Matrix effects occur even with methods such as plasma spectrometry , which have a reputation for being relatively free from interferences.

  9. Van 't Hoff factor - Wikipedia

    en.wikipedia.org/wiki/Van_'t_Hoff_factor

    The van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non- electrolytes dissolved in water, the van 't Hoff factor is essentially 1.
