Description
Reagent Set Powder Pillows reagents (2446600) for the determination of Oxygen Scavengers: Carbohydrazide, DEHA, Hydroquinone, Iso-ascorbic (erythorbic) Acid, Methylethylketoxime. Ferrous Iron values are also determined from Hach.
Аpplication: For testing residual corrosion inhibitors (oxygen scavengers) in boiler feed water or condensate.
Measuring range:
1) 13 - 1500 µg/L Eritorbična kiselina / izoaskorbinska kiselina (ISA)
2) 15 - 1000 µg/L Methylethylketoxime (MEKO)
3) 5 - 600 Carbohydrazide
4) 3 - 450 µg/L DEHA
5) 9 - 1000 µg/L Hydroquinone
Summary of method: Diethylhydroxylamine (DEHA) or other oxygen scavengers in the sample react with ferric iron in DEHA Reagent 2 Solution to produce ferrous ion in an amount that is equivalent to the DEHA concentration. This solution then reacts with DEHA 1 Reagent, which forms a purple color with ferrous iron that is proportional to the concentration of the oxygen scavenger. This method reacts with all oxygen scavengers and does not differentiate when the sample contains more than one type of oxygen scavenger. The measurement wavelength is 562 nm for spectrophotometers or 560 nm for colorimeters.
