Phenomenex has introduced the Zebron ZB-XLB-HT Inferno, a high-temperature GC column that provides routine GC/MS melamine analysis of milk products.
The ZB-XLB-HT is claimed to reduce total run time to less than four minutes and is stable up to 400C.
This high-temperature capability allows bake-off of matrix contamination, present in milk and other food products, which would otherwise decrease column lifetime.
The Zebron Inferno non-metal columns incorporate Phenomenex's coating and bonding technologies, providing stability at high temperatures, low bleed and low activity.
These Zebron columns expand Phenomenex's selection of tools for melamine analysis by GC and LC.
The company's Zebron ZB-5ms column is suitable for routine analysis of milk products using the FDA-recommended GC/MS method.
For customers who need faster results, Phenomenex has developed the Zebron ZB-XLB HT Inferno GC column.
If a lab prefers LC analysis, the Phenomenex Luna HILIC (hydrophilic interaction liquid chromatography) column resolves cyanuric acid and melamine in less than three minutes.
The Phenomenex LC/MS method does not require ion pairing agents and provides higher retention and peaks.
Phenomenex said that its Strata Melamine SPE (solid phase extraction) cartridges cut sample preparation times in half and simultaneously extract the deadly combination of melamine and cyanuric acid.
