EP pharmacopoeia GC column

[GT]

Dear all,
I've found this GC column description in a EP monograph.

"Column:
— material: fused silica;
— size: l = 10 m, Ø = 0.32 mm;
— stationary phase: styrene-divinylbenzene copolymer R."

Can you tell me which is the commercial name of this kind of column ?

Thanks

Hallo GT,

The EP monograph describes the main characteristics of the GC column which should be used for the specified method. That means that you can search from the product lists of the GC column manufacturers, a column with such characteristics (that column should have the specified characteristics if you want to gain good-reproducible results)

For example:
J&W Scientific (Agilent technologies) have a column with such characteristics:

HP - PLOT Q (bonded polystyrene-divinylbenzene based column)

ID(mm)......................................0.32
Length (m).................................15, 30
Film thickness(micron)................20.00
Temp.limits...............................-60 to 270/290C
Part.No.....................................19091P-Q03, 19091P-Q04 (adequate)

You can use 15m long column instead of 10m. The EP allows that kind of variation of the column length.

Best regards

An easier solution may be to visit the EP WWW site Knowledge Database and look up the column in the monograph data. If the following link doesn't work, just search the EP site for "Knowledge Database"
