Abstract

Fourier Transform Raman Spectroscopy (FT-Raman) determines the isomer ratio of chemical compositions.

Claims

exact text as granted — not AI-modified
1 . A Fourier Transform Raman spectroscopy method for mathematically determinating isomers within a chemical composition comprising the steps of: 
 creating a standard curve;    analyzing a chemical sample, wherein the isomeric ratio is determined.    
     
     
         2 . The method of  claim 1 , wherein the chemical sample comprises omeprazole and the ratio comprises a ratio of the 5-methoxy and 6-methoxy isomers of omeprazole on the benzimidazole moiety.  
     
     
         3 - 6 . (canceled)
