Application Note: Extraction of Lead from Maple Syrup by SPE
14 July 2009

Solid phase extraction using Empore™ chelation disks greatly simplifies the analysis of high-solid liquid food products such as maple syrup for lead and other transition metals. The chelation disk (paired iminodiacetate ions on a styrene divinylbenzene support) selectively extracts and concentrates trace levels of metal ions while the high concentrations of sugars pass through unretained.
