The range of TELOS neo polymer-based SPE products covers the five popular SPE retention mechanisms used in today’s analytical laboratory:

• TELOS neo PRP Polar-modified Reversed Phase (Non-polar)
• TELOS neo PCX Mixed-mode Cation Exchange
• TELOS neo WCX Mixed-mode Weak Cation Exchange
• TELOS neo PAX Mixed-mode Anion Exchange
• TELOS neo WAX Mixed-mode Weak Anion Exchange

Based on a water-wettable copolymer backbone, TELOS neo SPE Products provide all the advantages of using a polymeric sorbent, trouble-free method development and reliable operation in routine analysis. The combination of the water-wettable optimised surface chemistry, high surface area and pH stability ensure high and reproducible recoveries for a wide range of applications.  

TELOS neo PRP Polar-modified Reversed Phase SPE Sorbent Suitable for extraction of a wide range of analytes from aqueous samples, this reversed phase sorbent has an optimised combination of non-polar and hydrophilic character to retain analytes of wide-ranging polarity. Chemistry: Reversed Phase (non-polar/hydrophobic) Analytes: Acidic, neutral and basic compounds Order Online: SPE Columns or 96-well Plates  

TELOS neo PCX Mixed-mode Cation Exchange SPE Sorbent This sorbent is highly selective towards basic analytes. Use for the extraction of basic compounds with pK_a range from 6 – 10. See TELOS neo WCX for basic analytes with pK_a>10. Chemistry: Reversed Phase and Strong Cation Exchange Analytes: Basic compounds Order Online: SPE Columns or 96-well Plates  

TELOS neo WCX Mixed-mode Weak Cation Exchange SPE Sorbent Weak cation exchange should be selected for extraction of strong bases and quaternary amines, which would not be eluted efficiently from a strong cation exchange retention sorbent. Chemistry: Reversed Phase and Weak Cation Exchange Analytes: Strong bases, bases with multiple basic groups and quaternary amines Order Online: SPE Columns or 96-well Plates  

TELOS neo PAX Mixed-mode Anion Exchange SPE Sorbent This sorbent is highly selective towards acidic analytes. Use for the extraction of acidic compounds with pK_a range from 2 – 8. See TELOS neo WAX for acidic analytes with pK_a<2. Chemistry: Reversed Phase and Strong Anion Exchange Analytes: Acidic compounds Order Online: SPE Columns or 96-well Plates  

TELOS neo WAX Mixed-mode Weak Anion Exchange SPE Sorbent Weak anion exchange should be selected for extraction of strong acids, which would not be eluted efficiently from a strong anion exchange retention sorbent. Chemistry: Reversed Phase and Weak Anion Exchange Analytes: Strong acids Order Online: SPE Columns or 96-well Plates
