Introduction to fillers

As a solid-phase extraction technology（SPE）The core of solid-phase extraction packing is to useMonodisperse uniform particle size

Microspheres, with better chemical stability and wide widthpHValue range and surface functional groups,Traditional extraction fillers come in different sizes or shapes

Irregular conditions, Compared to traditional solid-phase extraction columns, it is more suitable forSample pretreatment using liquid chromatography, gas chromatography, or mass spectrometry to facilitate the adsorption and desorption of analytes onto stationary phase fillersThe elution process is more concentrated.

Widely used for sample pretreatment and analysis of various foods, agricultural and livestock products, cosmetics, environmental samples, etc

advantage

Monodisperse uniform particle size distribution, compared to similar typesSPEFillers have significant advantages

More optimized pore size distribution and surface functional group density, higher sample recovery rate, suitable for enriching trace target substances

Low solvent usage, concentrated elution, and reduced pressure on environmental pollution

More types of functional groups and optimized functional group density, widepHValue range, wider applicability

C18filler

C18(end-capping)Adsorbents are based on bonded reverse phase (octadecyltrichlorosilane), using high-purity irregular silica gel as the matrix, and treated with end group tail sealing. The typical reverse phase extraction retention mechanism has excellent strong retention properties for non-polar compounds and retains most organic compounds, making it the most widely usedSPEAdsorbent.

due toC18The long-chain effect of the filler is smaller than that of other adsorbents, and there is no retention of salt. It can usually be usedC18Small columns replace ion exchange columns for desalination of some small molecules and some medium-sized molecules.

C18Filler matrix indicators:

S011Silicone matrix,C%：18-19%, average granularity45μm, average pore size60 ?, pore volume0.8cm3/g, specific surface area480m2/g，pHScope of application2~8.

S012Silicone matrix,C%：23-24%, average granularity45μm, average pore size60 ?, pore volume0.8cm3/g, specific surface area480m2/g，pHScope of application2~8.

C18Advantages of filler products:

● Has high bonding density, low loss, and high recovery rate

High purity and controllable specific surface area ensure stable extraction efficiency

● * No blank background interference

● Can be used forSPEcombineGC/MSandLC/MSdetection technology

● Easy to operate, with a flow rate range that can be achieved under natural gravity and good reproducibility
