"Tx 20/40" (or Tx 20/40/40) would be a trimix blend with 20% oxygen, 40% helium and the remaining 40% nitrogen. This would be suitable for depths up to 60 metres (200 ft) if the partial pressure of oxygen is to be limited to 1.4 bar. This is a normoxic blend and is safe to use at the surface.
The method of mixing a known nitrox mix with helium allows analysis of the fractions of each gas using only an oxygen analyser, since the ratio of the oxygen fraction in the final mix to the oxygen fraction in the initial nitrox gives the fraction of nitrox in the final mix, hence the fractions of the three components are easily calculated.
Gas blending is the process of mixing gases for a specific purpose where the composition of the resulting mixture is defined, and therefore, controlled. A wide range of applications include scientific and industrial processes, food production and storage and breathing gases.

Summary of the main ethanol blends used around the world in 2013. Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in automobiles, light-duty trucks and motorcycles.

This act forbids the use of artificial colorings red dye No. 40, yellow dyes Nos. 5 and 6, blue dyes Nos. 1 and 2, and green dye No. 3 from foods served in schools.
Although, thorough mixing of gases and vapors may not be as easily accomplished. [citation needed] For example, if there are 10 grams of salt (the solute) dissolved in 1 litre of water (the solvent), this solution has a certain salt concentration . If one adds 1 litre of water to this solution, the salt concentration is reduced.
