Reflectoquant® Peracetic Acid Test, Catalog No. 16975/1
Peracetic acid reacts with an aromatic amine to
form a blue dye, the concentration of which is determined
2. Measuring Range and Number of Determinations
||Number of Determinations
|1.0 - 22.5mg/l peracetic acid
1) for measurement of concentrations
>22.5mg/l peracetic acid see section 6
This test is for the selective determination of
traces of peracetic acid in aqueous solutions and for checks for the
absence of peracetic acid after rinsing processes, also in cases in
which hydrogen peroxide is present.
Disinfectant and rinsing solutions (all types of
hospital laboratories and private medical laboratories, food
4. Influence of Foreign Substances
This was checked - in the case of interfering
ions up to concentrations of 1,000mg/l - in solutions containing 15
mg/l and 0 mg/l peracetic acid.. The concentrations of foreign
substances given in the table lie below the limit at which the
determination is interfered with:
Concentrations of Foreign Substances in mg/l
||Free chlorine (hypochlorite)
|Bound chlorine (chloramine T)
5. Reagents and Auxiliaries
Store originally sealed pack in
refrigerator. Opened pack: store closed tube outside refrigerator in
a cool and dry place. The analytic test strips are stable at least
up to the date stated on the pack when stored in these conditions.
Tube containing 50 analytical test strips
Bar code strip
EM Quant® Peracetic acid Test,
Cat. No. 10084, measuring range 5-50mg/l peracetic acid
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 22.5mg/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
at the same time immerse both reaction zones of the test
strip in the sample solution (15-30°C) for approx. 2 sec.
- Shake off excess liquid from the test strip
- 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. The
result is automatically stored.
