The TRUTH About Superficially-Porous Particles: Separate Fact From Fiction
Recently, manufacturers of superficially-porous particles claim that these products can provide UPLC-like performance on conventional HPLC systems. The reality is that nearly all chromatographic separations take place on fully-porous particle columns because they offer increased analyte loading capacity; full scalability from UPLC to preparative-scale column sizes; and inorganic-organic hybrid particles capable at working at the extremes of pH. None of this is possible with superficially-porous particle columns.  Find out the facts. |

Introducing Atlanta...
Did you know that the original name of the City of Atlanta was the more mundane and improbable “Terminus,” based on the fact that it sprouted up at the end of an old rail line?

Explore Agilent’s Clearly Better Mass Spec Solutions
Agilent mass spectrometry solutions are clearly better for good reasons. LC-MS with iFunnel technology gives the lowest detection limits. GC-MS-MS acquisition speed automatically quantifies and confirms more targets in a single method. ICP-MS High Matrix Introduction technology enables faster, easier ppt-level quantification of trace elements. Agilent MassHunter Software makes analyses faster, easier, and more productive Learn more at:  www.agilent.com/chem/clearlybetter |
