Hamilton Polymers - Poly(styrene divinylbenzene) or PS-DVB is a robust polymer material used as the base framework for all the Hamilton polymer HPLC packing materials. The high degree of cross-linking with divinylbenzene makes the polymer bead extremely durable for high pressure applications.
Can handle pressures over 5,000 psi Have a usable pH range of 1‐13 Polymer columns can be cleaned with 1.0 M sodium hydroxide to remove strongly retained material. Swelling in organic solvents such as THF or chloroform is negligible because of the cross‐linking Can be operated at much higher temperatures as compared to silica based materials Excellent sample recoveries due to the lack of acidic silanol groups PS‐DVB resins are similar in retention characteristics to a C18 but do have a slightly different selectivity in some cases.
