CHROMABOND® C18 ec
Octadecyl modified silica phase for SPE, endcapped
Base material silica, pore size 60 Å, particle size 45 µm for C
18 ec, 100 µm for C
18 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)....

CHROMABOND® QuEChERS extraction buffer mixes / clean-up mixes
QuEChERS method and pre-mixes
Within a few years after its devleopment by Anastassiades et al. the QuEChERS method has gained a leading position for determination of pesticide residues in food by GC-MS or LC-MS allowing rapid and cheap clean-up of strong matrix-contaminated samples.
Standard clean-up of food samples...
CHROMABOND® SiOH
Unmodified silica phase for SPE
Unmodified, weakly acidic silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8, very polar, adsorbs humidity from air, for this reason it should be kept well closed and if necessary dried before use due to its high affinity for polar compounds it should not be conditioned with polar (e.g. methanol) or water-containing solvents....
CHROMABOND® C18
Octadecyl modified silica phase for SPE, not endcapped
Base material silica, pore size 60 Å, particle size 45 µm for C
18, specific surface 500 m²/g, pH stability 2 to 8 octadecyl phases, not endcapped, carbon content 14 % possesses more free silanols (SiOH), which allow secondary interactions with polar groups of the analytes....
