Automated Near Real-Time QC for LC-HRMS. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale The quality of analytical measurements is typically evaluated after completion of the entire, or possibly multiple, measurement batch(es). Automated, near real‐time quality control (QC) during LC‐HRMS acquisition can prevent reruns and sample loss by flagging issues as they occur.

Bioinformatics analysis of the potential mechanisms of Alzheimer’s disease induced by exposure to combined triazine herbicides

Annals of Human Biology, 2023
Background The development of Alzheimer’s disease (AD) is promoted by a combination of genetic and environmental factors. Notably, combined exposure to triazine herbicides atrazine (ATR), simazine (SIM), and propazine (PRO) may promote the development of

Abnormal retention of s-triazine herbicides on porous graphitic carbon

Reviews in Analytical Chemistry, 2021
Porous graphitic carbon (PGC) is a widely used stationary phase for reversed-phase high-performance liquid chromatography (HPLC) that allows separation of structurally similar compounds retained in mixed form on a flat graphite surface. Such a stationary

The Comet Assay, a Sensitive Biomarker of Water Quality Improvement Following Adoption of Beneficial Agricultural Practices?

Environmental Toxicology and Chemistry, Volume 42, Issue 10, Page 2201-2214, October 2023., 2023
Abstract Numerous actions have been undertaken by farmers to attenuate the impact of agricultural activities on aquatic ecosystems. The identification of biomarkers that respond quickly to water quality improvement could facilitate the assessment of adopted alternative practices and help maintain mobilization among stakeholders.

Recent advances and future trends in molecularly imprinted polymers‐based sample preparation

Journal of Separation Science, Volume 46, Issue 12, June 2023., 2023
Molecular imprinting technology is a well‐established technique for the obtainment of tailor‐made polymers, so‐called molecularly imprinted polymers, with a predetermined selectivity towards a target analyte or structurally related compounds. Accordingly, molecularly imprinted polymers are considered excellent materials for sample preparation providing
