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.
Wasserlösliche Vitamine sind aufgrund ihrer Polarität mit der klassischen C18-HPLC nicht so einfach zu retardieren und zu trennen. Hierbei hilft eine polar modifizierte C18-Säule.
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.
Due to rapid growth in the medical cannabis industry, demand is increasing for analysis of residual solvents in cannabis concentrates in order to protect consumer safety. This application note details a simple, fast test for common residual solvents using full evaporation technique headspace GC-FID and an Rxi®-624Sil MS column.
