Introduction

Normal Phase Hydrophilic Phases

Polar-polar interactions

Dipole-dipole interactions

HyperSep Silica

A polar sorbent primarily used to retain analytes from

non-polar matrices

Surface area 530m

2

/g

Particle size 40 to 60µm

Pore size 60Å

Silica material is primarily used to extract analytes from non-polar

solvents such as hydrocarbons, less polar esters and ethers. Typical

application areas include extraction of aldehydes, amines, pesticides,

herbicides, carotenoids, fat soluble vitamins, aflatoxins, fatty acids

and phospholipids.

HyperSep Florisil

®

Ideal for the isolation of polar compounds from

non-polar matrices

Surface area 289m

2

/g

Particle size 40 to 60µm

Pore size 60Å

Florisil is a magnesia-loaded silica gel which has been specifically

designed for applications such as the extraction of pesticides using

AOAC and EPA methods, as well as polychlorinated biphenyls (PCBs)

in transformer oil.

HyperSep Aminopropyl

A polar sorbent for both polar and anion exchange interactions

Surface area 470 to 530m

2

/g

Particle size 40 to 60µm

Pore size 60Å

Aminopropyl is a silica-based material which can be used as both a

polar sorbent and a weak anion exchanger. Typical applications include

petroleum fractionation, saccharides, drugs and drug metabolites.

HyperSep Cyano

For retention of polar compounds from non-polar matrices

Surface area 470 to 530m

2

/g

Particle size 40 to 60µm

Pore size 60Å

Cyano is a silica-based material of low hydrophobicity. It is less retentive

than either silica or diol. Typical application areas include retention of

polar compounds from hexane and oil.

HyperSep Diol

For extraction of polar compounds

Surface area 470 to 530m

2

/g

Particle size 40 to 60µm

Pore size 60Å

A silica-based material which can be used for extraction of polar

compounds. Typical applications include normal phase extraction and

purification of polar compounds.

/g

Particle size 40 to 60µm

Pore size 60Å

SAX is ideal for the extraction of negatively charged compounds from

both aqueous and non-aqueous matrices, as well as the extraction of

weak acids such as carboxylic acid. Typical application areas include

removal of acidic food pigments, removal of phenolic compounds,

nucleic acids and surfactants.

HyperSep SCX (Strong Cation Exchanger)

Strong cation exchange sorbent for extraction of charged basic

compounds

Surface area 470 to 530m

2

/g

Particle size 40 to 60µm

Pore size 60Å

SCX is ideal for the extraction of positively charged compounds from

both aqueous and non-aqueous matrices. Typical application areas

include extraction of antibiotics, drugs, organic bases, amino acids,

catecholamines and herbicides.

Mixed-Mode Phases

Two functional groups

Non-polar and ion exchange

Hydrophobic and ionic retention
