Compared to the magnitude of unconventional oil and gas development activity that has been performed by industry, the amount of research to assess its potential environmental impact has been miniscule. Can the process have a deleterious impact if not well managed? Can it be performed in a responsible manner?

I often get asked about the other important aspects of “screening” in HPLC, which include the mobile phase composition, gradient parameters and flow rate – so that’s the theme of this installment.

Here, I will attempt to convey a few basic but critical concepts when getting started in the development of a new LCxLC method.

I’ve been talking about ‘ToolKit’ method development platforms a lot lately and I have to say I’m not sure we are making the most of this approach.

The Column
What is required to produce a highly efficient modern high performance liquid chromatography (HPLC) system/column combination? This instalment of the LCGC Blog explains more.

The literature on reversed-phase liquid chromatography of proteins is reasonably well developed, but not taught in the college classroom much. I would like to focus on a stoichiometric displacement model for reversed-phase LC of proteins and why it is particularly insightful from a practical perspective.

If you don’t examine your LC–MS data closely, you could be missing some of these effects, and those problems with your quantitative data will never be fixed.

Food analysis provides a rich sample matrix with many compounds of interest for analysis to contemplate—but one must always take care that the right tool is chosen for the desired task.

Some modern HPLC systems resemble spacecraft in terms of their technology, designed as they are to operate to the highest efficiencies, compared to traditional systems. However, I still see countless examples where high efficiency columns are used on systems which are not matched and cannot support the highest efficiencies offered by the column.

The Column
Column overload is a very commonly encountered issue in gas chromatography (GC) for beginners. Changes in peak symmetry, generally observed as peak fronting, can be subtle in the sharp peaks generated by GC, but the result can be significant shifts in retention times, loss of resolution, and error in peak integration. LCGC Blogger Kevin Schug explains more.
