R-9423 Detergents

R-9423 Detergents Kit is used with I-2017 to determine Detergent levels from 0-2.5 ppm.

Detergents Information


The R-9423 Detergents Kit was designed for use with I-2017 to accurately measure the Detergent levels in water from 0-2.50 ppm. R-9423 uses the Methylene Blue Method. The methylene blue active substances (MBAS) method is used in a 3-minute procedure to measure anionic detergents in the 0-3 ppm (mg/L) range. The procedure features a unique extraction/sampling technique that eliminates several steps required in other test procedures and provides increased sensitivity. Anionic detergents react with methylene blue to form a blue-colored complex that is extracted into an immiscible organic solvent. Results are expressed in ppm (mg/L) as linear alkylbenzene sulfonate (LAS), equivalent weight 325.

Detergents can be introduced into the water supply by industry, soap manufacturers, and private households. Environmental analysts often include a determination of anionic detergents when assessing surface water pollution.

  1. Rinse the red tipped plastic dropper bottle with sample to be tested.
  2. Fill dropper bottle to 15 mL mark with sample
  3. While holding the double-tipped ampoule in vertical position, snap upper tip.
  4. Invert the ampoule so the open end is over the reaction tube. Snap upper tip and allow contents to drain into dropper bottle. 
  5. Cap the dropper bottle, and shake vigorously for 30 seconds.
  6. Allow bottle to stand undisturbed for 1 minute.
  7. Remove cap, gently invert dropper bottle over a test tube and squeeze the bottle to deliver only the chloroform layer into the test tube.
  8. Stop squeezing when dark blue layer can be seen in the tapered tip of dropper bottle.
  9. Allow test tube to stand upright and undisturbed for 4 minutes.
  10. Place test tube into the photometer and obtain results.
