4-2. Primary and Secondary Standard Solutions. In volumetric titrimetry one uses a standard solution the concentration of which is known with great precision and which reacts stoichiometrically with the analyte. Standard solutions are referred to either as primary standards or secondary standards.Primary standards can be prepared by weighing directly and dissolving to a measured volume the ...

Concentration of sodium ions inside the plasma (extracellular) is 130-145 mmol/l. Higher and lower concentrations are referred to as hypernatremia and hyponatremia, respectively. When a solution containing cations of sodium and potassium is spayed into flame, the solvent evaporates and ions are converted into atomic state.

A simple flow injection with flame photometric detection has been developed for determination of sodium, potassium, and total alkalies in portland cement, fly ash, admixtures, and water of concrete. A liquid sample or a digest of solid sample was injected into a water carrier stream which flowed to a flame photometer. A change in emission intensity at a selected wavelength was recorded as a peak.
