INTip™ Solid Phase Extraction (SPE)

INTip SPE utilizes a patented technology known as Dispersive Pipette XTRaction. This device is unique from all other SPE devices because sorbent is loosely contained within a pipette tip.

The disperser helps to perturb the sample solution and loose sorbent during aspirate and dispense steps. This mixing provides a highly efficient interaction of the sorbent and sample solution resulting in ideal analyte recoveries and reduced matrix effects. You can seamlessly integrate XTR tips with any workflow or method.

XTR μElution -300 μL size tip

Product Description

μXTR Tips utilize a proprietary design to provide fast dispersive solid-phase XTRactions with minimal elution volumes for maximum concentration effects. Micro-elution tips are available with 1-3 mg of sorbent and utilize a unique low-retention frit. This allows for elution volumes as low as 25 μL, thereby eliminating time-consuming solvent evaporation steps. Currently this tip is available in Hamilton, or Integra formats. 

Advantages:

  • Same advantages as XTR
  • Eliminate solvent evaporation/dry down step
  • Increase sensitivity
  • Reduce elution volumes to as low as 25 μL for up to 8X concentration factor
  • No positive pressure/vacuum manifold
  • Compatible with all sorbents with > 50 μm particle size.

High Quality Sorbents

DPX offers sorbents chemistries in a range of phases to capture unique selectivity for a diverse spectrum of analytes. XTR tips are manufactured to order per custom specifications. They can hold 1 – 100 mg of sorbent depending on the tip format.

Supel™ Swift HLB SPE from Millipore Sigma is a proprietary and patent pending copolymer having both hydrophilic and lipophilic functional groups. The sorbent’s dual polarity nature makes it ideal for extracting a broad range of compounds from aqueous matrices, and is an appropriate choice in applications for food & environmental samples as well as biological samples such as urine, serum and plasma. The hydrophilic and lipophilic balance (HLB) property of the polymer material enables the retention of a wide range of compounds having a wide range of polarities and Log P values.

Our reversed phase sorbent is a styrene divinylbenzene polymer with an average particle size of 75 μm. It is ideal for nonpolar and slightly polar compounds.

Download Application Notes:

Our weak anion exchange (WAX) sorbent has a secondary amine phase with a styrene divinyl benzene backbone for the binding of strong acids, such as sulphates. WAX sorbents are offered in 10-20 μm and 55-65 μm particle size ranges.

Download Application Notes:

Our weak cation exchange (WCX) sorbent has a carboxylic acid stationary phase with a styrene divinyl benzene backbone for the binding of strong bases such as quaternary amines. WCX sorbent is offered in a 30-70 μm particle size range.

Our strong cation exchange (SCX) sorbent has a sulfonated stationary phase with a styrene divinyl benzene backbone for the binding of basic compounds. SCX sorbents are offered in 10-20 μm, 25-35 μm and 55-65 μm particle size ranges.

Download Application Notes:

Our strong anion exchange (SAX) sorbent has a quaternary amine phase with a styrene divinyl benzene backbone for the binding of acidic compounds. SAX sorbent is offered in a 55-65 μm particle size range.

Our silica sorbent is amenable to extraction via hydrogen bonding. It is available in a 40-60 μm particle size range.

Our C18 sorbent has a silica gel backbone. It is endcapped, with a carbon load of 18-22%, and 40-60 μm particle size range.

DPX is proud to offer HybridSPE® (a Supelco/Millipore Sigma product) sorbent. It is a proprietary zirconia coated silica that selectively removes phospholipids from biological samples.

  • Unique chemistry for excellent recovery of both hydrophobic and hydrophilic analytes

Download Application Notes:

Our mixed mode products are completely customized by choosing any of the above chemistries to combine in one tip. Each sorbent’s mass can also be customized for optimal extraction characteristics for any analyte/matrix combination.

Ex. WAX/RP, WAX/SCX

Download Application Notes:

Combine Dispersive Pipette XTRaction and SALLE (Salt Assisted Liquid-Liquid Extraction) for a novel cleanup mechanism. XTR tips can house sorbents like WAX or RP for cleanup and the salt (S) necessary for SALLE. This methodology is ideal for applications that require acetonitrile for protein precipitation and are focused on hydrophobic analytes.

Ex. WAX-S, RP-S

Aspirate and dispense steps mix sample solution and loose sorbent material. Added salt (S) assists in phase separation during extraction.
