The sample collection process has a decisive influence on the validity of the test results. Sample collection errors cannot be corrected in the subsequent course of testing.
MTSE GmbH collects a representative sample in accordance with GMP+ guidelines.
Quantitative analysis method
for Microtracers using the rotary detector
This is required in order to carry out the quantitative analysis of
Microtracer particles with the rotary detector method.
Weigh a certain quantity of sample on a scale.
Place a small round filter in the rotary detector (MTSE GmbH) and filter
the sample through the funnel of the rotary detector.
Remove the top hopper from the rotary detector. The Microtracer particles
that were separated from the sample are shown here.
Completely moisten a large filter paper with a development reagent.
Carefully remove the small round filter from the rotary detector without
losing any particles and demagnetise the Microtracer particles with a
demagnetiser.
Transfer the particles from the small to the large, wet filter paper so
that all the particles are arranged separately. Wait a moment until the
food colouring develops on the filter paper and stop the colour development
of the particles by placing the filter paper on a heated hotplate.
The dry filter paper with the developed colour spots is shown here. You can
now count the points by eye or automatically with the TraCo image assessment
and evaluation system.
Qualitative analysis method
for Microtracers using a Mason jar
This is required in order to carry out the qualitative analysis of
Microtracer particles with the Mason jar method.
Weigh a certain quantity of sample on a scale.
Place a round filter in the lid of the Mason jar (Micro Tracers Inc.)
and pour the sample into the Mason jar.
Screw the lid onto the jar. Shake the jar for about a minute – all
the sample particles should have touched the lid at least once.
Tap the lid of the Mason jar to remove any other, non-magnetic particles
that may be stuck to it.
Remove the lid of the Mason jar and turn it over. The Microtracer particles
that were separated from the sample are shown here.
Moisten the round filter with development reagent. Wait a moment until the
food colouring develops on the filter paper and stop the colour development
of the particles by placing the filter paper on a heated hotplate.
Based on the colour of the particles, it is now possible to tell very quickly
whether your product was used.
