CHROMABOND C ec

Macherey-Nagel GmbH & Co. KG (15180)

CHROMABOND® C18 ec
Octadecyl modified silica phase for SPE, endcapped

Base material silica, pore size 60 ?, particle size 45 µm for C18 ec, 100 µm for C18 ec f (for fast flow), specific surface 500 m²/g, pH stability 2 to 8. Octadecyl phases, endcapped, carbon content 14 % very non-polar, hydrophobic interactions with a wide variety of organic compounds. Advantageous for clean-up of samples with large structural variations (polarity differences).

Recommended applications: non-polar compounds, aflatoxins, amphetamines, antibiotics, antiepileptics, barbiturates, caffeine, drugs, preservatives, fatty acids, nicotine, PAHs, pesticides, PCBs, heavy metals, vitamins. Very well suited for desalting of samples.

CHROMABOND Easy

Macherey-Nagel GmbH & Co. KG (15179)

CHROMABOND® Easy
Polar modified polystyrene-divinylbenzene copolymer with a weak anion exchanger

Specific surface 650 to 700 m²/g, particle size 80µm, pore size 50 ?, pH stability 1 to 14. Due to bifunctional modification much more hydrophilic than conventional polystyrene-divinylbenzene polymers and thus easily wettable with water.

Recommended applications: polar herbicides / pesticides from water (acidic, neutral, basic), polar phenols from water, polyaromatic compounds, polychlorinated biphenyls, drug analysis from urine, blood, serum, plasma pharmaceuticals / active ingredients from tablets, creams.

Due to the bifunctional modification CHROMABOND® Easy is considerably more hydrophilic than conventional polystyrene-divinylbenzene polymers and thus easily wettable with water. The Easy effect: Aqueous samples can be loaded directly without preconditioning! This means that little or even no conditioning is needed, in contrast to standard SPE materials, where recovery rates normally decrease, in the worst case down to zero! Depending on the separation task conditioning may be required and is recommended for method development. A positive side effect of the excellent wettability: there is no decrease of recovery rates, if the cartridge runs dry, therefore automation is easier or, in some cases compared to silica materials, only feasible with CHROMABOND® Easy, because a permanent vacuum can be used without supervision.

Further advantages of using a polymeric material:
-high surface, this means very high binding capacity (2 - 5 times higher than silica-based adsorbents)
-less adsorbent is needed in the cartridge (without losing sensitivity or recovery)
-faster analysis, because the height of the adsorbent bed can be reduced
-acidic or basic solvents (e. g. TFA) do not destroy the phase, or lead to unintended side products
Because of the polar modification the material is suitable for a broad range of compounds (acidic, neutral, basic, polar and nonpolar substances). Highly reproducible recovery rates can be obtained, even if the cartridge runs dry (especially advantageous when using 96-well plates, where stopcocks are not available!)

CHROMABOND® SB
Quaternary ammonium modified silica anion exchanger for SPE (SAX)

Base material silica, pore size 60 ?, particle size 45 µm, specific surface 500 m²/g, pH stability 2 to 8. Silica modified with quaternary amine. Strongly basic anion exchanger (capacity ~ 0.3 meq/g). Not suited for very strong anions such as sulphonic acids, because these are difficult to elute.

Recommended application: organic acids, caffeine, saccharin.
