Non-targeted analysis of small molecules with ambient ionization mass spectrometry (AI-MS) is enabled by new mass spectral libraries and algorithms, such as the inverted library search algorithm (ILSA) developed at NIST.

Algorithms and Databases: Unlocking Non-Targeted Screening of Small Molecules with Ambient Ionization Mass Spectrometry

Are generic workflows really needed in environmental analysis? In the end, it is the analyst— not instrumentation or software—that is in charge of what data are obtained, after thoughtfully considering what sample preparation and acquisition method to use.

What’s Your Workflow? Non-Targeted Analysis of Water Samples

Gene therapy vectors in the gigadalton (GDa) regime are beyond the range of conventional mass spectrometry. Charge-detection MS overcomes this limitation.

Charge Detection Mass Spectrometry: Analysis of Gene Therapy Vectors

Extracting thousands of metabolomics features from LC–MS–based metabolomics data is not easy. A new suite of free bioinformatics tools helps address these metabolic peak-picking challenges and thus obtain more accurate biological information.

Turning Metabolomics Data Processing from a “Black Box” to a “White Box”

In this study, the experimental nontargeted screening approach and corresponding data analysis workflows—simultaneously using molecular ion information and structural information—are presented for the molecular identification and authenticity verification process from a brand perfume using GC–ecTOF-MS.

Nontargeted Screening for the Verification of Allergenic Ingredients and Perfume Authenticity by GC-ecTOF-MS

An overview of modern approaches to small-molecule drug discovery.

Small-Molecule Drug Discovery: Processes, Perspectives, Candidate Selection, and Career Opportunities for Analytical Chemists

Better sample preparation and miniaturized separations are enhancing these analyses.

Development of Highly Sensitive LC–MS and CE–MS Methods for In-Depth Proteomic and Glycomic Profiling of Limited Biological Samples

Sample preparation and analysis of pharmaceuticals in wastewater present unique challenges. Here, we describe those challenges.

Wastewater Surveillance of Pharmaceuticals and Genes: Challenges and Opportunities

The recruitment of young, talented entrepreneurs within academia and industry is needed to tackle many of the challenges that exist today and that will emerge tomorrow.

A Field Full of Opportunities: Transforming the Future of Separation Science

Further miniaturization of separations will greatly extend the reach of single-cell proteomics, metabolomics, and lipidomics, but key challenges in instrumentation, column technology, and ionization sources must be addressed.
