Liquid chromatography and mass spectrometery (LC-MS) have transformed the field of proteomics, enabling researchers to rapidly survey the contents of complex biological samples. However, until relatively recently it has proven challenging and labor-intensive to perform accurate comparisons across multiple samples.

Tandem mass tags (TMT) have proven to be a transformative tool in this regard. Using TMT technology, researchers can add isobaric labels to multiple samples, which can then be analyzed in a single tandem MS experiment. These capabilities are making it possible to sensitively detect rare peptide species, to identify differences between healthy and diseased tissue, and conduct sophisticated surveys of the cellular proteome. This ebook provides an overview of the TMT technology, and offers five case studies that illustrate some of the cutting-edge applications for which these reagents are being used.

The coatings industry, just like every other segment of the chemical industry, is innovating in response to new and expanding environmental regulations. As one of the world's biggest users of chemical ingredients, coatings manufacturers are under intense pressure to meet new standards but also provide affordable and efficient products. Innovative companies have responded with new additives that help achieve goals such as reducing levels of hazardous air pollutants (HAPs) and volatile organic compounds (VOC), as well as making certain that coatings that come in contact with foods are up to today's safety standards.

Compact mass spectrometers (CMS) have revolutionized reaction monitoring, turning a once laborious and time-consuming task into a rapid and convenient process with instruments right at the chemist's bench or fume hood. These instrument can provide results in as few as 30 seconds, are cost-effective, and offer a growing number of sample techniques. This report reviews the advantages and applications of CMS systems as well as some case studies in their use.

From protein folding to the function of medicines in the body, water is essential to countless chemical reactions that sustain life. Recently, the advent of liquid cell transmission electron microscopy has brought these tiny interactions to light with high-resolution imaging. Using customizable sample holders, researchers are now performing water-based science experiments inside the electron microscope.

Homogeneous, assembled, digitized analytical data lends itself to be included in the stream of meaningful data exchange between external organizations and data-sharing inside organizations. This organization and data transformation is necessary to effectively build the ‘data-to-information-to-knowledge’ lineage that enables managers to make strategic and tactical decisions; to maximize benefits, and limit risks. This paper provides commentary on efforts for analytical data standardization and a vision of the broader considerations and requirements that such an undertaking should include.

Ongoing evolution of new designer drugs, also known as new psychoactive substances (NPS), requires continuous updating of screening methods when determining the suspected role of NPS in deaths. The open library concept of the Toxtyper system allows for rapid updates of methods linked to the appearance of new drugs.
