We have added the "GO-209PCB column set" to the GO-EHT column lineup and had begun selling it since January 2025.

This product proposes a fully automated sample preparation method using GO-EHT, by combining columns filled with the activated carbon that can adsorb only PCDDs/PCDFs using hexane as the mobile phase, and the transition metal oxides (TMO) that can adsorb all 209 PCB isomers that pass through the activated carbon.
Using these new columns enables simultaneous pretreatment for the measurement of PCDDs/PCDFs for EPA1613 and PCBs for EPA1668C.
