Reflectoquant® Peracetic Test, Catalog No. 16976/1
Peracetic acid reacts with a phenol derivative
to form a red-violet dye, the concentration of which is determined
2. Measuring Range and Number of Determinations
||Number of Determinations
|75 - 400mg/l peracetic acid
1)for measurement of concentrations >
400mg/l peracetic acid, see section 6
This test is suited for the selective
determination of the peracetic acid concentration in disinfectant
solutions, also in cases in which hydrogen peroxide is present.
4. Influence of Foreign Substances
This was checked - in the case of interfering
ions up to concentrations of 1,000mg/l - in solutions containing 75
and 350mg/l peracetic acid. The concentrations of foreign substances
given in the table lie below the limit at which the determination is
Concentrations of Foreign Substances in mg/l
||Free chlorine (hypochlorite)
||Bound chlorine (chloramine
5. Reagents and Auxiliaries
The analytical test strips are stable at
least up to the date stated on the pack when stored in the closed tube
at +2 to +8°C.
Tube containing 50 analytical test strips

EM Quant® Peracetic Acid Test,
measuring range 5-50 mg/l, Cat. No. 10084
Check whether the peracetic acid content is
within the measuring range. Use the EM Quant®
Peracetic Acid Test as a guide. Samples containing more than 400 mg/l
peracetic acid must be diluted with distilled water.
- Observe the instructions for the RQflex
The following applies to the Peracetic acid
Measurement procedure A. Stored reaction
time: 15 sec.
- Remove 1 analytical test strip and immediately
reclose the tube.
- Press START button of the reflectometer
and--this is imperative--at the same time immerse both reaction
zones of the test strip in the measurement solution (15-30°C)
for approx. 2 sec.
- Vigorously shake off excess liquid from the
- As soon as the beeper sounds (5 sec before
end of reaction time), insert the test strip all the way into the
strip adapter with the reaction zones facing the display.
- Read off the result from the display in mg/l
peracetic acid. The result is automatically stored.
- If the test strip is inserted into the
adapter after the reaction time has expired, renewed depression of
the START button may result in a false reading of the peracetic acid
- At the end of each workday, cleanse the
strip adapter thoroughly with water or ethanol.
