Mapping measurement using the IQ Mapping function of Jasco IRT-5000 FTIR microscope

IR mapping measurement which can visualize molecular structure has been suggested traditionally, however the IR mapping measurement has not been widely utlized because of the several reasons as below. 

• Auto stage is required, which will make the instrument too expensive.
• It takes quite a long time for measurement.

Regarding the measurement time, using the system utilizing multielements detector enables to shorten the measurement time in more than double digits in comparison with conventional system, and the IR mapping measurement has been gradually used. This time, Jasco introduces IQ Mapping which was developed in order to solve another problem which is the necessity of auto stage. The IQ Mapping is a technique allowing Mapping measurement with manual stage by scanning IR light, and is applicable to ATR as well as ordinary transmittance/reflectance mapping. Here is an example of impurity analysis using IQ Mapping of the IRT-5000.
