Sample Preparation

Scientists from Dalian Maritime University in Dalian, China, are testing a new amphetamine-type stimulant extraction system on wastewater and urine samples.

A team of scientists from Universitat Rovira i Virgili in Tarragona, Spain, is investigating a new method for testing water samples for contaminants of emerging concern.

Scientists based out of Zhejiang Academy of Agricultural Sciences in Hangzhou, China, recently used a new QuEChERS method for analyzing pesticides in fruit samples.

A pair of scientists from Gdańsk University of Technology (GUT) in Gdańsk, Poland, used the method to analyze the presence of antibiotics in animal products like milk and eggs.

With expert speakers coming in from around the country for Cannabis Science Conference Fall, we thought it was a great opportunity to introduce some of them and get a sneak peek into their presentations. Here, we meet Jini Glaros, Chief Scientific Officer at Modern Canna Labs.

The 27th International Symposium on Separation Sciences (ISSS 2023) will be held 24–27 September 2023 in Cluj-Napoca, Romania. Here’s a sneak preview of what attendees can look forwards to.

Accelerated solvent extraction (ASE) is widely viewed as a better alternative to GC–MS when analyzing persistent organic pollutants (POPs). The authors explain why new technological developments offer many benefits and accelerate POP sample preparation processes.

An examination of the principles behind “salting out,” and when it can be applied in analytical extractions to enhance the extraction yield.

On a fundamental level, equilibrium and diffusion define chemical separations.

Plant growth regulators (PGRs) have significant effects on plant physiological processes, but the complex matrices of plants, along with polarity and instability issues inherent with PGRs, complicate trace analysis of these compounds.

During a presentation at the North America Chemical Residue Workshop, scientists described a method for pesticide analysis using liquid chromatography-tandem mass spectrometry and gas chromatography-tandem mass spectrometry.

Researchers have recalibrated polyparameter linear free energy relationships (PP-LFERs) for low-density polyethylene (LDPE) passive samplers. By utilizing a robust regression method and reliable partition coefficients and solute descriptors, the recalibrated models exhibited improved predictive performance, accurately estimating LDPE-water and LDPE-air partition coefficients across a wide range of compounds.

A separation science team has developed a green and cost-effective method, called feather fiber-supported liquid extraction (FF-SLE), for determining synthetic antioxidants in edible oils.

This blog addresses the essential role software has in shaping the present and future of chromatography for the better.

In a lecture at HPLC 2023, Valérie Pichon of ESPCI Paris and Sorbonne University said these advances address limitations of more traditional extraction techniques.

In his plenary lecture at HPLC 2023, Michal Holčapek presented his team's findings on how chromatography can help scientists record the human lipodome and better our understanding of diseases.

At HPLC 2023, Kelly Zhang gave a lecture on how machine learning can help further our understanding of the characterization of lipid nanoparticles.
