A review highlighting the recent development on flow-injection analysis (FIA)–mass spectrometry (MS) to bring more attention to this effort.
Multidimensional separations, in which two or more separation methods are coupled, are a valuable analytical tool for higher peak capacity and improved selectivity for the analysis of complex samples like biotherapeutics.
Tuesday, June 22, 2021 at 10am EDT | 3pm BST | 4pm CEST Leverage UHPLC-like performance using monolithic 2 mm-I.D. columns. Increase lab efficiency with trouble-free, fast, and efficient HPLC of challenging and matrix-rich samples.
A study of colony collapse disorder in honey bees illustrates how mass spectrometry–based proteomics techniques can be used to to identify pathogens without any prior knowledge of what is contained in the sample.
The two year international project "Preparation of active packaging with antioxidant and antimicrobial activity based on astaxanthin and chitosan",1 which started in 2009, was funded by FONCYCIT (Fund for International Cooperation of Science and Technology between the European Union and Mexico).
Turbulent flow chromatography is often used for on-line sample cleanup of biological matrices in liquid chromatography–mass spectrometry applications.
Here, the process to build an accurate mass database is thoroughly described and applications are commented on.
Under a suitable thermal oxidation regime, vegetable oils yield a mixture of volatile and semivolatile organics that exhibit very high antimicrobial activities against a variety of microbial species. Volatile and semivolatile products were characterized with GC–MS using electron ionization and chemical ionization. The thermal oxidation of vegetable oils resulted in the formation of an array of short and medium-chain acids, aldehydes, and ketones that act synergistically to yield a potent antimicrobial disinfectant.
This paper provides an overview of some current and emerging physicochemical analytical challenges associated with these sophisticated drug systems and some of the technical advances needed in chromatographic systems to enable their design, development, and manufacture.
Crop development to improve yield or disease resistance has been explored for centuries and the technologies to measure these improvements have subsequently become complex.
A discovery-based, untargeted metabolomics analysis of hundreds of yeast metabolites under robust, controlled extraction conditions followed by identification is described.
A new method to deal with the interaction of transition metals with analytes has been developed and is described.
This article presents a new column technology that uses reversed phase separation and offers excellent peak shape, resolution, and robustness for a wide variety of food matrices.
The main limitations of quantification using MALDI imaging are discussed and the different approaches used for quantitative measurement in MSI are evaluated.
Gas chromatography–mass spectrometry (GC–MS) and liquid chromatography–mass spectrometry (LC–MS) techniques offer advantages in separating and confirming the identity of constituents in novel psychoactive substances.
It is well established that food-producing animals are exposed to toxic micropollutants via environment and feeds, and that micropollutants entering the animals are transferred to edible tissues, thus representing a chemical human health hazard.
The paralytic shellfish toxins are a group of 18 secondary metabolites deposited in bivalve mollusks by dinoflagelates. Dinoflagelate blooms are seasonal, occurring during warm months.

This article explores three case studies where autosampler injection programs help to (i) reduce the carry-over observed for large nucleic acids during anion-exchange chromatography (AEX), (ii) reduce peak distortion and breakthrough for monoclonal antibodies (mAbs) during hydrophilic-interaction chromatography (HILIC), and (iii) facilitate dissolution of lipid nanoparticles (LNPs) so that a size-exclusion chromatography (SEC) method can be applied for ribonucleic acid (RNA) payload analysis.
Describes a novel approach for the enantioselective separation of spearmint oil incorporating a fluidic modulation system.
