Using Second-Order Data in Chromatographic Analysis
LCGC Europe
The authors discuss zero-, first- and second-order data and describe the advantages of using second-order chromatographic data compared with the more traditional univariate or multivariate calibration. They demonstrate how its use can uncover much more information from chromatograms and spectra.
18 Scientists from the US and Canada Win Scialog Awards for Advancing Chemical Lab Automation
July 7th 2025Seven research teams from universities across the United States and Canada have been honored for their collaborative efforts that integrate automation and artificial intelligence (AI) to tackle fundamental scientific challenges.
Detection and Risk Assessment of Mycotoxins in Commercial Tortillas Using HPLC-Based Methods
July 4th 2025A joint study between Selçuk University (Konya, Turkey) and Hitit University (Corum, Turkey) determined the natural occurrence and concentrations of the mycotoxins ochratoxin A (OTA) and deoxynivalenol (DON) in commercially available tortillas in Turkey. Contamination levels were quantified using validated analytical methods based on high-performance liquid chromatography (HPLC) coupled with fluorescence or ultraviolet detectors (HPLC-FLD or HPLC–UV).
GC Analysis Reveals PCB Accumulation in Antarctic Penguins and Krill
July 3rd 2025Researchers from the University of Murcia (Murcia, Spain), the Carlos III Health Institute (Madrid, Spain), and the University of Siena (Siena, Italy) evaluated the concentration of polychlorinated biphenyls (PCBs) in chinstrap penguins and krill from Deception Island (South Shetland Islands, Antarctica) to provide additional data of the PCB presence in Antarctica. To this end, 34 samples of different tissues corresponding to four adult specimens and six chicks were analyzed with gas chromatography.
