A panel discussion on the latest advances and future developments in gas chromatography mass spectrometry (GC–MS).
Get set for greater success in your career as an analytical chemist, with Incognito’s practical suggestions that will make you stand out from the crowd. These tips for excellence will enlighten employees and employers alike.
This article explores the role of SPE sorbents for analyte recovery rates and method accuracy to develop clean samples for analysis and to reach lower limits of detection.
This study demonstrates how the technique can improve on traditional methods in the analysis of VOCs that contribute to the aroma and flavour of a breakfast cereal and in identifying other compounds of interest, such as food additives, contaminants, and potentially toxic compounds at trace levels.
In any given community, on rare occasions, leaders converge on a big idea. The development of such an idea alters the course of the community, in a way that is meaningful if it is lasting. It is my belief that the collective chromatography community is currently converging on a big idea.
An analysis method for influenza virus particles has been developed using SEC which provides complimentary biopharmaceutical data for use during vaccine production and approval.
Researchers have developed a rapid and sensitive technique for the speciation analysis of complexes of nickel, lead, cobalt, iron, and calcium, as well as two aminopolycarboxylate chelator variants, EDTA and EDDS.

The diverse nature of oligonucleotide therapeutics leads to the requirement for multiple separation methods to characterize quality attributes. Highly chemically-modified to improve efficacy and resilience to nucleases, they are challenging to analyse using a single method. This article discusses multiple chromatographic separation methods, and the benefits of mass spectrometry (MS).
This article explores the potential of microchip capillary electrophoresis–mass spectrometry (CE–MS) for the characterization of intact biopharmaceuticals, and how this technique can effectively be employed to monitor essential quality attributes of interest.

Capillary GC is renowned for being a ”high efficiency” technique, meaning that we typically see very narrow peaks within our chromatograms. This leads to the ability to separate many components in a reasonable amount of time, which is of course analytically advantageous.

Pretty much every commercial chromatography column has some sort of release testing done on it before it leaves the manufacturer. Just how valuable are those tests to the end user? Should column Certificates of Analysis go straight to the rubbish bin?

This article demonstrates the sensitivity of an automated thermal desorber coupled to a GC–MS for TO-17 VOCs analysis targeting from propene to naphthalene.
This application note demonstrates using evolved gas analysis and multi-step pyrolysis as a powerful toolset to unveil both additives and polymer backbone.

The 2020 Eastern Analytical Symposium has gone virtual for 2020, and although we will miss the camaraderie of face to face interaction, the theme of this year’s conference “Analytical Science: Cornerstone of Innovation” indicates the strength of the separation sciences and the talks that you will not want to miss.

Oliver Napoleon Hill (1883– 1970) was an American self-help author once described as ”the most famous conman you’ve probably never heard of” (1 ). Conman maybe, but there is a quote of his that I believe to be particularly true when considering sample preparation for chromatography techniques; ”The one who tries to get something for nothing generally winds up getting nothing for something.”
In this panel of veterninary drugs from a milk sample, SPE displays an improved solution over traditional protein precipitation methods and other types of SPE, due to clean up efficiency, all while maintaining a rapid and fast analysis time.
