Handheld 1064nm Raman boosts excipient analysis capacity
Pharmaceutical manufacturers the world over seek more efficient technologies for materials validation. Implementation of handheld Raman spectrometers utilising a 785nm wavelength laser revealed a limitation in the technology’s ability to identify many common materials, often excipients. Instrument miniaturization advancements resulted in the incorporation of a 1064nm longer wavelength laser into handheld Raman spectrometers and has proven valuable in minimizing limitations observed using the shorter 785nm wavelength laser. A study of common excipients proved that Rigaku Raman’s FirstGuard™ 1064nm provided chemically specific data necessary for pharmaceutical material verification requirements.
