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%.
Fourier Transform Infrared Spectrometer
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
Streak Camera / Spectrometer
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
