ILE Caps New Improved Design Cat Nos
Unique Improved "SPE-type  Technique"

Methodology

• Extract directly from any aqueous matrix without protein precipitation or sorbent conditioning.

• No emulsions, clogging, or analyte breakthrough.

• Lower elution volumes with the solvent of your choice (solvent exchange never required).

• Extracting solvent (polymer) applied to contaminant-free PTFE sealing surface

• Extract directly into autosampler vials using ILE Back-Extraction Adapter.

• Reduced solvent usage.

• No need for expensive equipment like thermal desorption units or vacuum manifolds.

Simple Two-Step Method

• (1) Extract: Place ILE Cap on sample-containing vessel. Invert vessel such that sample is directly exposed to immobilized solvent (polymer). Agitate Vessel.

• (2) Back-Extract: Remove ILE Cap from sample vessel. Dispense mobile phase into autosampler vial.
  Using back-extraction adapter, secure autosampler vial with ILE Cap. Invert vessel and agitate.

Application Notes
  ILE CAPS Cat# / Prices
  The Immobilized Liquid Extraction™ (ILE) Cap is regular bottle or vial cap with a siloxane-elastomer coated septum.
Targeted analytes are extracted from a sample into the immobilized elastomer coating, from which they are back-extracted (eluted) into a small amount of mobile phase.
The New ILE Cap utilizes a unique well design that ensures that the cap is not sealed by the extracting media, but rather by a contaminant-free PTFE sealing surface.
ILE Caps have been designed to utilize beneficial aspects of other sample preparation procedures while avoiding their numerous shortcomings.

ILE Method Development Kit - Immobilised Liquid Extraction Kits are a risk free way to develop a method for your specific applications. For $150 each kit includes 5 ILE Caps of each phase ) PDMS, Acrylate, Fluoro, Phenyl ), an ILE Back-extraction adaptor, and full method development assistance. If you are unable to develop an appropriate method, simply return the plates to us within 30 days of receipt for a full refund. Or, if you decide to place a second order, the original purchase price of $150 will be credited towards it
* ILE Cap kits come with 25ul phase ILE Caps, 10ul caps may be substituted on request.

Polydimethylsiloxane (PDMS) - Relatively non-polar phase for extracting hydrophobic compounds.
It has been experimentally shown that PDMS exhibits polarity and extractive properties similar to n-octanol.
It is recommended as a general purpose ILE phase and is suitable for a wide range of extractions.

Polydiphenylsiloxane (Phenyl) - This is a more polar phase, and would be expected to display enhanced selectivity for aromatic compounds due to pi-bonding potential - a similar effect to extracting with toluene.

  Trifluoropropylmethylsiloxane (Fluoro) - This phase provides enhanced selectivity for extracting compounds with lone pairs of electron
