半岛bd体育手机客户端 说明

一般描述

Highly cross-linked polymethacrylate base material of TSKgel Octadecyl-2PW provides excellent stability in high pH buffer systems and can withstand rigorous cleaning with either acid or base. The 125? pores allow for anaylsis of peptides up to 8,000 Da. Columns packed with larger particle sizes are available for semi-preparative scale separations.
Polymer-based particles for reversed-phase (RP) HPLC generally have two benefits over silica-based particles: They are more tolerant of high and low pH operating conditions and they do not have the silanol interactions that cause peak tailing of some basic analytes. Also, some silicas have an intrinsic metal content that may cause chelation problems with sensitive biomolecules, leading to poor recovery. Polymeric TSKgel columns come in C18 and phenyl functional groups and a range of particle porosities. Fast kinetics and quantitative protein recovery at submicrogram loading are characteristic of nonporous resin-based TSKgel Octadecyl-NPR columns.

  • Octadecyl-2PW particles have 125? pores
  • Octadecyl-4PW particles have 500? pores
  • Phenyl-5PW RP particles have 1000? pores
  • Octadecyl-NPR particles are nonporous
