On-chip CO2 control for microfluidic cell culture

January 1, 2011
Author(s)
Samuel P. Forry, Laurie E. Locascio
Carbon dioxide partial pressure (PCO2) was controlled on-chip by flowing pre-equilibrated aqueous solutions through control channels across the device. Elevated PCO2 (e.g. 0.05 atm) was modulated in neighboring stagnant channels via equilibration through

Performance of a coherent dual frequency comb spectrometer

Nathan R. Newbury, Esther Baumann, Ian R. Coddington, Fabrizio R. Giorgetta, William C. Swann, Alexander M. Zolot
We discuss the performance of a coherent dual frequency comb spectrometer in terms of signal-to-noise ratio, resolution, and accuracy based on experimental data in the near and short-wave infrared centered at 1.5 and 3.4 micrometers.
