Extract hydrophobic or polar organic analytes from aqueous matrices TELOS nonpolar (reversed phase) SPE columns are available in a wide range of sorbents for extraction of hydrophobic and polar analytes. Select columns with endcaps for applications requiring minimal secondary silanol…

Extract polar analytes from nonaqueous matrices Use the TELOS polar (normal phase) SPE cartridges to retain analytes of interest or to remove polar interferences from the sample. Columns with Florisil® PR grade (magnesium silicate) sorbent have larger particle size than NH2 and are…

Mixed-mode weak cation exchange columns for strong basic analyte extraction High surface area and capacity ensure highly reliable retention characteristics No secondary interactions from silanol groups for accurate results Higher sample loading due to high surface area Recover…

CBA (Carboxylic Acid) is excellent for extracting strongly basic and polybasic analytes from aqueous sample matrices. The weak cation exchange sorbent with pKa 4.8, allows analytes to be eluted by eliminating the charge on the sorbent at low pH. The sorbent is supplied in the free acid form.…
