Paired Ion Electrospray Ionization for Trace Anion Analysis
Using electrospray ionization mass spectrometry (ESI-MS) to perform quantitative binding analyses and determine association constants depends on the ability of the ionization process to preserve the system equilibrium. If association or dissociation kinetics are relatively fast, then the shrinking-droplet ESI process can alter equilibria. This is not good for studying noncovalent complexation in solution, but it is central to the success of a technique called paired ion electrospray ionization (PIESI). |

Luigi Mondello on 2D GC In Food Analysis
Comprehensive gas chromatography (GC) was introduced more than two decades ago, but is still considered to be a novel technique. Luigi Mondello from the University of Messina, Italy, talks about why this is the case and what it will take for it to become more widely used. |

GC Temperature Programming—10 Things You Absolutely Need to Know
Temperature affects not only retention but also relative retention in gas chromatography (GC) and therefore, when we change temperature, we also change the selectivity of the separation. This is true as we alter the isothermal separation temperature, but also as we change the slope of the temperature program gradient.
