Next Generation Spectrometers for Rapid Analysis of Complex Mixtures

Abstract

A chirped-pulse mm-wave spectrometer was constructed using a real-time digitizer and amplified multiplier chains. The real-time digitizer performance greatly increased data throughput relative to previous digitizers. Spectral data on methanol at mm-wave frequencies was obtained and used to optimize chirped-pulse bandwidth, duration, and sample pressure. Efforts to miniaturize the sample cell proved unsuccessful due to failure of the mm-wave components. The primary technical hurdles to overcome for future work are the low available output powers of the multiplier chains as well as the low power handling capabilities of the mm-wave receiver components.
