Total dissolved solids ( TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular ( colloidal sol) suspended form. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter.
Conductivity (electrolytic) Conductivity or specific conductance of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m). Conductivity measurements are used routinely in many industrial and environmental applications as a fast, inexpensive and reliable way of ...
Sodium tetradecyl sulfate. CCCCC (CC)CCC (CC (C)C)OS (=O) (=O) [O-]. [Na+] Sodium tetradecyl sulfate ( STS) is a common anionic surfactant. The compound consists of the sodium salt of the micelle -forming sulfate ester of tetradecanol. It is a white, water-soluble solid of low toxicity with many practical uses. [1]
Total suspended solids. Total suspended solids ( TSS) is the dry-weight of suspended particles, that are not dissolved, in a sample of water that can be trapped by a filter that is analyzed using a filtration apparatus known as sintered glass crucible. TSS is a water quality parameter used to assess the quality of a specimen of any type of ...
Tetraethyl orthosilicate, formally named tetraethoxysilane ( TEOS ), ethyl silicate is the organic chemical compound with the formula Si (OC 2 H 5) 4. TEOS is a colorless liquid. It degrades in water. TEOS is the ethyl ester of orthosilicic acid, Si (OH) 4. It is the most prevalent alkoxide of silicon.
Triethylenetetramine ( TETA and trien ), also known as trientine ( INN) when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2. The pure freebase is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air-oxidation. It is soluble in polar solvents.
Coffee extraction occurs when hot water is poured over coffee grounds, causing desirable compounds such as caffeine, carbohydrates, lipids, melanoidins and acids to be extracted from the grounds. The degree to which extraction occurs depends on a number of factors, such as water temperature, brewing time, grind fineness, and quantity of grounds.
Tetrasodium EDTA is the salt resulting from the neutralization of ethylenediaminetetraacetic acid with four equivalents of sodium hydroxide (or an equivalent sodium base). It is a white solid that is highly soluble in water. Commercial samples are often hydrated, e.g. Na 4 EDTA. 4H 2 O.
