Replaces a 5%diphenyl column for high-resolution
dioxin and furan analyses
–
Improves sensitivity due to lower bleed levels
–
Improves separation ofmany congeners
•
May replace high-cyano columns as confirmation column
to the 5%diphenyl
–
All but 2 congenerswerewithin 10% of the fly ashmedian
values
• These 2 can be quantitatedusing the 5%diphenyl column
