Titrets Total Alkalinity Kits for Total and Hydrate
Titrets Method-Titrets ampoules use reverse titration to quantify concentrations. After snapping the ampoule tip, the sample is drawn into the ampoule in small doses (with the Titrettor device included in each kit that precisely controls the sample) (Step 1), until a color change signals that the equivalence point has been reached (Step 2). The titration is stopped at the end point and the ampoule is held upright. The liquid level will correspond to a printed scale on the ampoule's outer surface (Step 3). Kits include 30 ampoules with valve assemblies, a titrettor, accessory solution(s) (when necessary), a sample cup, and instructions. Material Safety Data Sheets are provided in test kits. Each Titret ampoule is 13 mm in diameter designed for titrimetric analysis. The ampoule contains vacuum-sealed liquid titrant and has a flexible valve assembly attached.
Product Description
Alkalinity (total)
References: ASTM D 1067-92, Acidity or Alkalinity of Water, Test Method B. APHA Standard Methods, 20th ed., pp. 2-27, Method 2320 B (1998). USEPA Methods for Chemical Analysis of Water and Wastes, Method 310.1 (1983).
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.
Alkalinity inhibits corrosion in boiler and cooling waters. It is also measured as a means of controlling water and wastewater treatment processes or the quality of various process waters.
CHEMetrics total alkalinity tests determine total or M alkalinity using a hydrochloric acid titrant and a bromocresol green/methyl red indicator. The end point of the titration occurs at pH 4.5. Results are expressed as ppm (mg/L) CaCO3.
Alkalinity (hydrate)
Reference: Developed with Calgon Corporation. Hydrate alkalinity is a component of total alkalinity. Boiler operators must maintain relatively high hydrate alkalinity levels when phosphate cycle treatments are used to ensure the formation of softer, more easily removable deposits. This specific test for hydrate alkalinity provides a more accurate value than the calculation method.
The hydrate alkalinity reagent has been specially formulated to inhibit interference from carbonate and bicarbonate alkalinity, as well as up to one-third of the phosphate and silicate alkalinity. For hydrate alkalinity, CHEMetrics developed a titrimetric method that uses a hydrochloric acid titrant with a phenolphthalein indicator and an inhibiting agent. The end point of the titration occurs at pH 8.3. Results are expressed as ppm (mg/L) NaOH.
