Phenomenex Introduces New Biozen dSEC LC Columns

Torrance, Calif. (February 19, 2021) – Phenomenex Inc., a global leader in the research and manufacture of advanced technologies for the separation sciences introduces Zebron™ ZB-Dioxin . Zebron ZB-Dioxin joins Phenomenex’s large family of GC unlimited Phase to deliver optimal performance when analyzing polychlorinated biphenyls (PCBs) and Dioxins regulated such as 2,3,7,8-tetrachlorodibenzo- para-dioxin (2,3,7,8-TCDD) and 2,3,7,8 tetrachlorodibenzo- para-furan(TCDF).

EPA-1613 and EPA-8290 Dioxin methods requires two GC columns, 5% phenyl and 225 GC columns (one for testing and one for confirmation) on two GC-HRMS instruments. The new Zebron ZB-Dixon exceeds EPA Dioxin method requirement by providing enhanced resolution for all Dioxin isomers using one GC column and single HRMS instrument.

Zebron ZB-Dioxin provides a single column Dioxin solution, reducing instrument down-time by 50%. This improves lab productivity, provides better sensitivity and offers greater resolution for the analysis of dioxins.

"In addition to its fast Dioxins analysis, our new ZB-Dioxin GC column is proven to be a one single solution to PCBs while providing excellent stability at elevated Temperature (300/320 °C)” explains Rola El Abaji, Product Marketing manager for Phenomenex and Dr. Ramkumar Dhandapani, Global Product Manager for Phenomenex "In addition, we have further improved column lifetime option with the ZB-Dixon Guardian with integrated column version.”

Zebron ZB-Dioxin columns were developed to address a customer need for greater resolution of Dioxins and PCBs in Food, and Environmental samples. The ZB-Dioxin exceeded not only EPA but our customers’ expectations:

“The ZB-Dioxin achieves superior resolution for both 2,3,7,8-TCDD and 2,3,7,8-TCDF while not only maintaining chromatography for the hexes but improving it. This is all performed while reducing the overall runtime over traditional 5ms dioxin columns by as much as 25%. The ZB-Dioxin increases throughput by not only eliminating the need for a second column confirmation, but also by allowing additional samples to be analyzed in each 12-hour analytical sequence”
--Andrew Patterson, Eurofins USA

Phenomenex also offers a range of GC accessories for better GC column and instrument protection for Dioxin analysis, including Zebron Plus liner and Zebron Gas Management.
