Do I need to run my sample through the Oasis HLB sorbent before the Oasis mixed-mode sorbents to remove phospholipids? - WKB233143

Article number: 233143

ENVIRONMENT

  • Oasis
  • Solid-phase extraction
  • Mixed-mode sorbent
  • WAX
  • WCX
  • MAX
  • MCX
  • Phospholipids

ANSWER

It is not necessary to use an additional Oasis HLB sorbent prior to using the Oasis Mixed-Mode sorbents: Oasis MCX, Oasis WCX, Oasis MAX or Oasis WAX.

ADDITIONAL INFORMATION

The Oasis Mixed-Mode sorbents retain by a dual mechanism: reverse phase and ion exchange. They remove most matrix interferences, including phospholipids.

For additional information see What is the retention mechanism for Oasis MAX? and What is the retention mechanism of Oasis WAX?

and What is the retention mechanism when using Oasis WCX solid-phase extraction devices?

and What is the mechanism of retention when using Oasis MCX solid-phase extraction devices?
