Sodium (Na-)

Sodium (Na-) is used in water purification. It may be used as a counter ion of calcium and magnesium in water softeners. Caustic soda and sodium percarbonate are applied to neutralize acids.

    Sodium Analyzer Edmund Eysler Overview

    The Sodium Analyzer Edmund Eysler can perform continuous analysis of heavy metals, such as Sodium (Na-), and many other parameters in water. Technologies employed are ion-selective electrodes (ISE) and colorimetric (photometric). Low consumption of reagents and very high reagent stability ensures person-free operation, direct measurements, standard addition, and titration support the ideal measurement strategy. The robust design and high-quality parts of the Sodium Analyzer guarantee a long lifetime and minimum maintenance efforts. Automated calibration and cleaning steps support this goal.

    The Earth's crust contains 2.27% sodium, making it the seventh most abundant element on Earth and the fifth most abundant metal, behind aluminum, iron, calcium, and magnesium and ahead of potassium. Sodium's estimated oceanic abundance is 1.08×104 milligrams per liter. Because of its high reactivity, it is never found as a pure element. It is found in many different minerals, some very soluble, such as halite and natron, others much less soluble, such as amphibole and zeolite. The insolubility of certain sodium minerals such as cryolite and feldspar arises from their polymeric anions, which in the case of feldspar is a polysilicate.

    After taking the sample the ionic strength adjuster is added to perform a stable and fast electrode signal. The concentration is calculated on basis of the calibration which is done fully automated. In a heavy matrix situation, we recommend using the double standard addition method where Sodium is added to the sample to get the matrix effect into the calibration adjustment. Also, real continuous measurement is an option and can be used to get a real continuous data stream.
