Two Dimensional Liquid Chromatography: A Powerful Tool for The Characterization of Humic Substances
Analysis of natural compounds is becoming increasingly important. One thriving area is the evaluation and application of environmental biopolymers, such as humic substances (HSs) in various applications, including medicine, industry, agriculture and environmental protection.
Analysis of natural compounds is becoming increasingly important. One thriving area is the evaluation and application of environmental biopolymers, such as humic substances (HSs) in various applications, including medicine, industry, agriculture and environmental protection. Such work is aided by ancient knowledge on the biological activity of HSs and their interactions with other living organisms. HSs — along with cellulose and chitin — are some of the most common types of organic matter on Earth.
Extracting Estrogenic Hormones Using Rotating Disk and Modified Clays
April 14th 2025University of Caldas and University of Chile researchers extracted estrogenic hormones from wastewater samples using rotating disk sorption extraction. After extraction, the concentrated analytes were measured using liquid chromatography coupled with photodiode array detection (HPLC-PDA).
Polysorbate Quantification and Degradation Analysis via LC and Charged Aerosol Detection
April 9th 2025Scientists from ThermoFisher Scientific published a review article in the Journal of Chromatography A that provided an overview of HPLC analysis using charged aerosol detection can help with polysorbate quantification.
Removing Double-Stranded RNA Impurities Using Chromatography
