Determination of Active Pharmaceutical Ingredients by Heteroatom Selective Detection Using Inductively Coupled Plasma Mass Spectrometry with Ultrasonic Nebuilization and Membrane Desolvation Sample Introduction

Carnahan, Jon W.; Kwok, Kaho; Carr, John E.; Webster, Gregory K. (Optical Society of America, 2006)

The combination of ultrasonic nebulization with membrane desolvation (USN-MD) is utilized to determine active pharmaceutical ingredients (API) by heteroatom inductively coupled mass spectroscopy (ICP-MS) detection. ...
Development and Application of Acousto-Optic Background Correction for Inductively Coupled Plasma Atomic Emission Spectrometry

Carnahan, Jon W.; Miller, Heather M.; Spudich, Thomas M. (Optical Society of America, 2003)

In two con gurations, a solid-state acousto-optic (AO) de ector or modulator is mounted in a 0.5 m monochromator for background correction with inductively coupled plasma atomic emission spectrometry (ICP-AES). A fused ...
Characterization of an Acousto-optic Tunable Filter and Use in Visible Spectrophotometry

Carnahan, Jon W.; Bucher, Ewa G. (Optical Society of America, 1999)

The use of a paratellurite acousto-optic tunable ® lter (AOTF) is demonstrated as a monochromator for spectrophotometry. This device operates in the range of 400 to 700 nm with a resolution from 2.5 nm (at 633 nm) to ...
