Florisil cartridges are a long-standing choice for the cleanup of organochlorine pesticide samples, and they are still a good choice when you are confident that your samples are relatively clean and free of low-volatility compounds that can be deposited in inlets and on the heads of columns. The ability of Florisil adsorbent to retain highly polar compounds also makes it ideal if your sample contains polar matrix components. However, if you know or suspect that your samples contain relatively nonpolar matrix contaminants, or if your samples are highly colored, CarboPrep Plus cartridges will do a better job of removing compounds that will contaminate inlets and result in premature failure of calibration check standards.
When should I use CarboPrep Plus cartridges instead of Florisil cartridges for the cleanup of samples being analyzed for organochlorine pesticides (e.g., EPA Method 8081)?
