ABSTRACT
Routine preparation methods of liquid and solid samples for IR analysis are introduced, deficiencies of conventional KBr pellet and liquid film most often used are pointed out and a modified preparation method of sample is put forward, i.e. preparing a liquid film by using two blank KBr pellets or by dipping blank KBr pellet into solution which is the mixture of sample and low boiling point organic solvent. For low boiling point liquid sample, a liquid film is prepared by using two blank KBr pellets; for high boiling point liquid sample, dipping a blank KBr pellet is used; for solid sample, dipping a blank KBr pellet is used as well. From the comparison of routine and modified preparation methods, this new method can meet the need of qualitative analysis and overcome the deficiencies of conventional KBr pellet and liquid film.
