  2. Total dissolved solids - Wikipedia

    en.wikipedia.org/wiki/Total_dissolved_solids

    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.

  3. Conductivity (electrolytic) - Wikipedia

    en.wikipedia.org/wiki/Conductivity_(electrolytic)

    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 ...

  8. Total suspended solids - Wikipedia

    en.wikipedia.org/wiki/Total_suspended_solids

    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 ...

  9. Triethylenetetramine - Wikipedia

    en.wikipedia.org/wiki/Triethylenetetramine

    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.
