Raman Spectroscopy: Raman Spectroscopy Detects Adulterated Counter-ions In Pharmaceuticals
A study published in the Journal of Raman Spectroscopy demonstrates how Raman spectroscopy can serve as an accurate, cost-effective method for detecting counter-ion adulteration in pharmaceutical products.
The study highlights that many drug salts rely on specific API and counter-ion combinations for therapeutic efficacy. In one case, a medication was found to contain a different counter-ion than listed on the label, potentially impacting its effectiveness.
Three additional case studies show how Raman spectroscopy can be used as a faster, more scalable alternative to traditional methods like HPLC-UV, offering an efficient way to confirm both the drug and its counter-ion.
