Simplify and speed up sample preparation with Resprep® dSPE tubes! Here we show the extraction and cleanup of pesticide residues from olive oil samples—twice as fast as GPC, with only a fraction of the solvent required for conventional SPE.
Optimized Efficiency, Selectivity, and Robustness Let You:
• Report accurate results with speed and con!dence.
• Prevent false positives for important isobaric PAHs.
• Reduce downtime with fewer column changes.
Electronic cigarettes (e-cigarettes) are growing in popularity exponentially. Despite their ever-growing acceptance, relatively little work has been done to characterize their vapor. To date, the majority of e-cigarette research has focused on characterizing the solutions, which are ultimately vaporized for the end user to inhale.
Abstract: Polycyclic aromatic hydrocarbons (PAHs) are toxic compounds found in some foods, especially those that are smoked, roasted, grilled, or dried during preparation. Yerba mate (Ilex paraguariensis) tea is of particular interest because of relatively high PAH levels and proposed links between yerba mate tea and health problems.
