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.
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.
