These elements may coine with the reactive alkali and alkaline-earth metals such as sodium, calcium and potassium. Most metallic materials coine with oxygen as oxides. X-ray photoelectron spectroscopy (XPS), also known as electron spectroscopy for chemical analysis (ESCA), is a technique for analyzing the surface chemistry of a material.

Potassium - Wikipedia

Potassium is the second least dense metal after lithium.It is a soft solid with a low melting point, and can be easily cut with a knife.Freshly cut potassium is silvery in appearance, but it begins to tarnish toward gray immediately on exposure to air. In a flame test, potassium and its compounds emit a lilac color with a emission wavelength of 766.5 nanometers.

The tube used (green-stoppered tube) contains a minuscule concentration of lithium and sodium, which does not interfere with plasma sodium or osmolality measurements. Frozen plasma or urinary samples can be kept for further analysis of their osmolalities, because the results obtained are similar to those obtained immediately after blood sampling, except in patients with severe renal failure.
