Reflectoquant® Blank Strip, Catalog No. 16730/1
1. General
When analyzing colored samples using
the Reflectoquant® system - consisting of
Reflectoquant® test kits and the Rqflex reflectometer
- the intrinsic coloration can, in given circumstances, produce more
or less pronounced false-high results.
In some cases, Reflectoquant®
blank strips can be used to correct these measurement values without
having to take time-consuming sample-pretreatment measures.
As an alternative, it is also possible to
eliminate the intrinsic coloration of the sample prior to analysis by
treatment with suitable sorbents (e.g. Divergan® RS or
activated charcoal).
Whether a correction of measured values is
necessary and technically possible is a question that must be checked
in each individual case, e.g. using the standard-addition method.
For examples, please refer to the corresponding
Reflectoquant® applications.
2. Package contents:
Tube containing 50 blank strips
| The strips are stable at least up to
the date stated on the pack when stored in the closed tube at +15 to
+25°C. |
3. Procedure
In each of the following working steps, proceed
according to the instructions given in the package insert of the
corresponding Reflectoquant® test kit.
- Analyze the colored sample using the
analytical test strips from the test kit in question (measurement
value A).
- Repeat the analysis of the colored sample
using the blank strips (blank value B)
