• Nitroterephthalic acid-modified Polyethylene glycol (PEG) • High polar stationary phase • High temperature to 250°C • High efficiency, high inertness columns

VertiBond™ AqWAX column contains Nitroterephthalic acidmodified Polyethylene Glycol stationary phase. This modified high polar phase resists damage by water-based samples and ideal for the analysis of acidic compounds, such as phenols, and derivatized or un-derivatized free fatty acids.
