Agilent says that to avoid co-elution of COS and Propylene , "select low sulfur column" (CP8575) should be used. I wanted to know what the equivalent column from RESTEK or SCION is. ASTM D6228 complies with this analysis

If you read paragraph 6.2.3 of the method, you will see that other columns can be used.

6.2.3 The column shall provide adequate retention and
resolution characteristics under the experimental conditions
described in 7.3. One example of a capillary column and
operating conditions used with the FPD is shown in Table 1.
Two examples of columns and operating conditions used with
the PFPD are shown in Table 2. Other columns, which can
provide equivalent separation, can be used as well.
