Hardness is a measure of the mineral content of water. Calcium and magnesium are the most common minerals that contribute to hardness. Hard water causes scaling in boilers and other industrial equipment, and diminishes the effectiveness of soaps and detergents. The EDTA Method (Total) …

Phosphorus occurs naturally in rock formations in the earth's crust, usually as phosphate. High phosphate concentrations in surface waters may indicate fertilizer runoff, domestic waste discharge, or the presence of industrial effluents or detergents. Although phosphates from these sources are…

The CHEMetrics chlorine comparator is an ideal thing to have in any chemical laboratories, medicinal facilities or healthcare units for a wide range of purposes such as scientific research and development.

Ethylene glycol and propylene glycol are the primary ingredients in commercially-available antifreezes. They are used with various corrosion inhibitors to protect metal surfaces in cooling water systems. CHEMetrics glycol kits are used to monitor potable waters for glycol contamination…

Phenol (hydroxybenzene) is the simplest of a group of similar organic chemicals, which includes cresols, xylenols, and catechols. Phenol itself is a common ingredient of disinfectants. In drinking water, low-level phenolic concentrations impart a foul taste and odor, especially upon chlorination.…

Method Dissolved carbon dioxide (CO₂) is naturally present as a result of animal respiration, the decay of organic matter, and the decomposition of certain minerals. It is the major source of acidity in unpolluted water samples. Surface waters typically contain less than 10 ppm…

Methods The alkalinity of water is a measurement of its buffering capacity. Alkalinity of natural waters is typically a combination of bicarbonate, carbonate, and hydroxide ions. Sewage and wastewaters usually exhibit higher alkalinities due to the presence of silicates and phosphates. …

The CHEMetrics phosphate comparator with a range of 0 to 1200 ppm is an ideal thing to have in any chemical laboratories, medicinal facilities or healthcare units for a wide range of purposes such as scientific research and development.

Persulfate is a strong oxidizer that is commonly used for clarifying swimming pools and spas and for the destruction of a broad range of soil and groundwater contaminants. Sodium persulfate is frequently used for environmental applications. The Ferric Thiocyanate Method Reference: D.F.…

Sulfides are naturally present in ground waters as a result of leaching from sulfur-containing mineral deposits. Surface waters do not usually contain high sulfide concentrations. Sulfides result from the decomposition of organic matter, from bacterial sulfate reduction under anaerobic conditions…

The CHEMetrics sulfide comparator is a suitable thing to have in any chemical laboratories, medicinal facilities or healthcare units for a wide range of applications such as scientific research and development.

The CHEMetrics sulfide comparator is a perfect thing to have in any chemical laboratories, medicinal facilities or healthcare units for a wide range of applications such as scientific research and development.
