Hyperpolarization Summary

This summer I set out to¬†get a previously existing parahydrogen hyperpolarization setup to work on a single-sided magnet (see previous posts for a more in-depth explanation of what those words mean). The biggest obstacle to achieving my goal was the production of parahydrogen. Our catalyst setup at the start was not functioning, but after some […]

Update 7: The Importance of a Clean GC Needle

This week, I began by repeating the photochem experiment from late last week. I did this in order to gather more data points on turnover numbers since they were relatively inconsistent last week. However, these experiments varied catalyst concentrations by very small amounts. Therefore, I also began a new photochem experiment with the same catalyst, […]

Update 6: pH Problems and a New Project

Last week, I ran into problems when using my third catalyst and chromophore combination. Over the weekend I learned that the chromophore I was using works best at pH = 7. The solution of sacrificial electron donor that I use is pH = 7, but I have been diluting it with deionized water. The pH […]
