Application of Ambient Sampling Portable Mass Spectrometry Toward On-Site Screening of Clandestine Drug Operations
Worldwide trends in illicit drug use and production have shifted toward an increase in synthetic analogues and the emergence of new variations in their manufacture. MORE » |
GC–MS Analysis of an Herbal Medicinal Remedy to Identify Potential Toxic Compounds
Canola largely contains unsaturated fatty acids, thus rendering it clear in most cases after extraction and refining. However, canola can become cloudy even at room temperature. The cloudiness is thought to be largely because of the presence of wax esters transferred to the oil from the plant tissues during extraction and increased saturated fatty acid content. MORE » |

Information Rich Flash Chromatography II: All-Wavelength Collection and Purity Measurement
Teledyne Isco
UV-visible detectors have been used on flash chromatography systems for several years to control the fraction collector. The purity measurements were limited to ratio measurements that required a priori knowledge of the spectra of the compound and impurities so that the correct wavelengths could be used both to collect peaks and determine purity.

Large-Scale Targeted Protein Quantification Using Wide Selected-Ion Monitoring Data-Independent Acquisition
This article describes the development of a new data-independent acquisition (DIA) workflow for protein quantification that uses a mass spectrometer that combines three types of mass analyzers to achieve lower limits of detection (LOD), higher sensitivity, more accurate quantitative results, wider dynamic range, and better reproducibility than existing high-resolution accurate-mass (HRAM) tandem mass spectrometry (MS-MS) DIA workflows.
