write 2 full paragraphs on IR spectroscopy wherein techniques are defined and explained thoroughly. Explain what kinds of samples are analyzed and how instrument analyzes the sample. Describe if it is possible for technique to distinguish enantiomers and if so, how. Give details about how the technique is used in forensic science.

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
