With new image analysis software for infrared spectroscopy, semi-quantitative studies can be performed without the use of standards providing rapid measurements of component concentrations when an approximate value is suitable or when quantitative standards are not available. Infrared spectroscopy has been used for many years to identify the composition of organic and other materials. Single or multi-component samples can be analyzed and their chemical structures determined by comparing their absorbance peaks to known spectral libraries or fundamental molecular transitions. This technique is used throughout the scientific community and provides rich information.
