Spectroscopic techniques for tablets

The rapid and non-destructive analysis features of NIR make it an ideal method to investigate film-coated tablets. Kirsch and Drennen101 analyzed theophylline tablets 

In the interest of patient safety, there exists a need for final identification testing of products as they are packaged for delivery to the patient. Herkert etal.lls evaluated a reflectance NIR instrument and found it to be capable of on-line identity check of tablets at-line speeds of 12 000 tablets a minute.
