Phenomenex Inc. introduced Strata Melamine, a solid phase extraction (SPE) sorbent specially designed for food testing. Strata Melamine SPE cartridges simultaneously extract both melamine and cyanuric acid, cutting sample time in half compared to other methods, according to the company. The Strata Melamine optimized method produces injection-ready samples for LC/MS or GC/MS analysis.
Phenomenex has also developed optimized LC/MS and GC/MS methods that work with Strata Melamine SPE cartridges. The LC/MS method uses the company’s Luna HILIC (hydrophilic interaction liquid chromatography) column to resolve cyanuric acid and melamine in less than three minutes. The Phenomenex LC/MS method is superior to previously recommended ion exchange chromatography methods because it does not require ion pairing agents, according to the company. The GC/MS method uses the new Zebron ZB-XLB-HT Inferno column and is an improved version of the FDA method, resulting in complete analysis in half the time.
Strata Melamine is available in 200 mg/ 3mL and 100 mg/3 mL SPE cartridges.
