I have written previously about occupying the middle ground in the debate over the environmental implications of unconventional oil and gas extraction operations. It seems we are just in the right place, when we are criticized and praised at separate times by proponents of both extreme views—namely those who think UOG is perfectly safe and those who think it cannot be done without ruining the environment.

A short treatment of what to consider when choosing the appropriate sample solvent so you can be better informed when developing, optimizing, transferring, or troubleshooting your GC methods.

Students who have an internship on their resume, and are seeking jobs in a particular sector, are doing so with an informed opinion. While an internship comes in many forms, that real-world experience has provided a clear touchstone of understanding of what it would be like to work in a given sector.

This time I’m going to be looking at how to get the most from your GC–MS (Gas Chromatography–Mass Spectrometry) system, and I intend to keep things as simple as possible, however I also make no apology in the fact that some of the concepts may be beyond your current understanding. My intention here is to explain some of the basics so that you will be able to use your instrumentation to best effect.

The LCGC Blog
For the most part, we are still instructing undergraduate students in the same way as when I went to school, and I think this is a disservice to the students and to the nature of chemistry. No wonder chemistry programs have trouble attracting students compared to other science disciplines, like biology and psychology. Students will take general chemistry, but they cannot see where it may lead. I want to change that.

As I wrote the title of this LCGC Blog instalment, I could not help but wonder where the cliché “more than one way to skin a cat” came from. Turns out it is from Mark Twain in his 1889 work, A Connecticut Yankee in King Arthur’s Court. I have never read that book, but I certainly have heard this saying used more than once — even if it might offend some cat lovers. Of course, it means simply that there is more than one way to do something.

Many of our instrument techniques rely on a calibration in order to relate the detector response to the amount of analyte within our sample.

Our technical support center deals with many issues regarding irreproducibility of retention and selectivity in reversed phase HPLC. Very often, the problem lies in poor equilibration of the HPLC column between injection, which in gradient HPLC can affect the separation selectivity as well as analyte retention.

In 2011, when we first began field and laboratory studies to help assess the potential environmental impacts of unconventional oil and gas extraction (UOG), there was very little literature on the subject. Further, the polarizing nature of the topic made it quite difficult to navigate the middle ground. While some voices contended that UOG was perfectly safe, others insisted that it should be banned in its entirety because it is destroying the environment. As with any topic that is both complex and elicits the attention of a large number of people (like our past election or politics, in general), my skepticism forces me to believe that the answer actually lies somewhere in the middle of extreme views.
