I would like to know the specific difference between a capillary column and a wide bore column and the advantages of such a column (wide bore).

Thank you already!

Jorim

The main deferent between the widbore column and capillary column is the widbore column has 0.53 mm as inerdiameter

That's simple, but what would be a reason to use a wide bore column ??

Column capacity is higher with wide bore column...that's the only reason...!

Jorim,
Actually there is another excellent reason one might use a wide-bore capillary, that is most packed column inlets can be converted to use the wide-bore cap columns (meaning you don't need to order a new injector for your GC). The only change you need is some way to add make-up gas to the flame detector (I have used a dual inlet GC and used the second inlet as the gas source for the make-up tee at the detector) This makes for a very inexpensive conversion to a cap column instrument (no. it isn't the most efficient but it certainly is better than running packed columns).
Regards,
Mark
