Chromatography Forum

Dear member of this forum,

I am looking for information about characteristics of Lichrospher 100RP-18 (5 um). The information solicited is: pH range, maximum pressure, yes or no endcapping and other relevant properties you considered.
Thanks in advance for your help,

Diego

Dear Diego,

In the Phenomenex Catalog, page 379, you can find some of the answers you are looking for.

Lichrosorb RP18 has a pore size of 100A, a pore volume of 1.25 ml/g, a surface area of 250m2/g, a carbvon load of 21.4%, a phase coverage opf 3.9 umole/m2, and no end capping.

The pH range must be between 2.5 and 7.5 as for most common materials. As for the maximum pressure, that is never clearly stated, but I suspect it will be around 400 atmospheres.

Good Luck,

benjamin
