IR spectrometer
Mr. Jiří Karel, chemistry and
biology
teacher,
showd
us
IR
spectrometer and how does it work. IR
spectrometer uses infrared radiation to
find out the content of the examined
substance. It send infrared rays through
the substance and than register unique
reaction of the substance.
The device can then compare the
reaction with the database. We tried it on
polyethylen and it worked well. Than we
crushed a pill and we mixed it with
potassium bromide. We obtained a
powder and we pressed it with some
device. This proces created another small
pill. Then we put it into the spectrometer
and find out that it is made of
paracetamol.
