Cross-reference of GC Columns

[smarcinko]

In the ACS monograph for GC chromatography, Type I, Type II and Type III columns are listed. Does any know the cross-references to the USP classification and or what type of Restek or Agilent columns these would refer to?

Thanks

Dear Stephen,

Despite a career using gas chromatography spanning 1/4" packed columns to the modern ultra-thin capillary ones, I don't recall using that terminology. A quick internet search doesn't show any specific "hits" either! Without a reference to the specific publication I couldn't really comment on what is being distinguished by the "Types". It is possible that it is an older monograph with out-dated terminology that may have referred to the different sizes or packing systems in use, or possibly polarities. They may refer to the USP designations of "L, G, S" for packing, or for the similar selectivity (polarity again). Even the USP designations are getting a bit 'old' in terms of published dates. Chromatographic Columns | USP

Unless there is some regulatory requirement (which I don't see, and which should define the terms), the importance of column design for a desired separation and reliability is the key issue. The major providers of chromatography columns should be able to help you out with that.

Best regards,

Steven
