UHPLC Column Protection System for Any Sub-2 µm or Kinetex

Column
Protects with No Loss of Column Performance!
With SecurityGuard ULTRA, contaminants and microparticulates are trapped within the
guard cartridge instead of in your expensive UHPLC column. The extremely low dead vol-
ume (<0.3 L) of this unique guard design minimizes sample peak dispersion to maintain
column performance without altering your chromatography results.
