Chemical Analysis

Shimadzu GC 2014 gas chromatograph, equipped with a thermal conductivity detector (TCD), flame ionization detector (FID), and two independent flow paths. The first flow path, equipped with HayeSep D and molecular sieve 5A packed columns, allows separation of permanent gases. The second flow path, equipped with HayeSep D packed columns, allows for analysis of larger hydrocarbon molecules.  

Thermal conductivity detector response to hydrogen released via maleic acid catalyzed hydrolysis of ammonia borane. Hydrogen was shown to be 100% pure, with uncertainty of ±5%.

 

The Agilent Cary 680 FTIR spectrometer is capable of Fourier transform infrared spectroscopy (FTIR) of condensed and gas phase samples.

• Spectral range from 9,000-350 cm-1
• ~110 spectra/second at 16 cm-1 resolution for kinetics experiments
• Ventilated enclosure allows experiments with toxic materials
• The Pike GladiATR accessory uses a diamond crystal internal reflection element that enables study of corrosive condensed phase samples

A gas purity study was performed using FTIR with a short path gas cell to identify contaminate species

The ROSS 2000 streak camera is an ultrahigh-speed spectroscopic detector capable of:

• Spectral imaging encompassing the UV and Visible ranges from 200-900 nm
• Spectroscopic measurement at time scales applicable to hypergolic reactions
• Sweeps over durations of 300 ns to 30 ms with a temporal resolution < 40 ps
• Simultaneous measurements over a maximum of 180 nm wavelength range
