Whatman SPE devices are designed to concentrate or isolate analytes from
complex sample matrices. Available with a variety of packing media,
these devices offer the advantage of working with different types of
interactions between the sample components, sorbent and suitable eluent.
The polarity (polar, nonpolar) or charge (anion, cation) of the analyte
of interest will determine the proper choice of sorbent and solvent.
Whatman SPE devices have silica-based chemistries and are available
in several configurations. Column capacities include 3, 6 and 12 mL size
columns. A cartridge format for use with a syringe is also available.
Solid phase extraction is a chromatographic technique used to prepare
samples for subsequent analysis by removing interfering substances that
may be present. This is done either by retaining the substance of
interest and washing off everything else or by retaining the interfering
substances and eluting the product of interest.
Whatman SPE devices contain high quality sorbets for LC
chromatographers.
Features and Benefits
- Available in a range of packing media
- Whatman quality sorbents for consistent results
Applications
- Isolate analytes from complex sample matrices
- Remove interfering substances in order to prepare samples for
subsequent analysis
- Drug metabolites in biological fluids
- Food analysis
- Environmental analysis
Solid Phase Extraction (SPE) Disks
The Whatman SPE disk utilizes C-18 derivatized silica, incorporated
into a glass microfiber matrix. The high flow and high loading capacity
of the glass microfiber media allow for rapid aqueous sample flow rates,
while oil, grease and other organic analytes are efficiently extracted
and retained by the reverse phase silica material.
Features and Benefits
- High quality Whatman glass microfiber media for superior flow
and high loading capacity
- Efficient grease analyte extraction and retention
Applications
- Oil and grease analysis, EPA Method 1664A
Sample Drying Device
A sample drying device is available for removal of water from organic
extracts. It attaches to the male luer outlet of a syringe in which the
organic sample extract has been collected. Traces of water are removed
as the sample is pushed through the drying device into a collection
vial.
