✦ Synopsis

TCDD retention time. These results are similar to those obtained by Buser and Rappe [lo] who made use of temperature programming with a50-m OV-17glasscapillarycolumnforaseries of PCDDs. Forthe TCDDs, the elution order listed in Table 1 is very similar to, but not identical with, the order reported by Buser and Rappe [2] using a temperature programmed 50-m OV-101 glass capillary column.

Because access to many of these PCDDs is still very limited, it is felt that these data will be useful to other researchers in the field of PCDD analysis by HRGC or HRGCIMS.

Acknowledgment

We are grateful to H. R. Buser (Swiss Federal Research Station, Switzerland) and C. Rappe (U. of Umea, Sweden) for the 22 TCDD isomers and to Dow Chemical Co. (USA) for the 1,2,3,4,7,8-HxCDD. We also thankD. Firestone (Food and Drug Administration, USA) for the other PCDDs which were not obtained commercially.
