No. Even though CarboPrep Plus cartridges have been carefully designed to permit excellent recoveries of organochlorine pesticides, the adsorbent material does have a different selectivity than Florisil material. That different selectivity is what makes it so good at stopping the relatively nonvolatile compounds in sample matrices that can contaminate inlets and columns. However, that difference also means certain traditional gauges of Florisil cartridge quality (e.g., the retention 2,4,5-trichlorophenol) cannot be used to validate CarboPrep Plus cartridges.
The retention of 2,4,5-trichlorophenol is sometimes used as a measure of Florisil cartridge performance. Can I use the same measure to validate CarboPrep Plus cartridges?
