  • 通过 GC-FID 和 GC-MS 测试其出色的净化效果

應用


  • Pipette-tip SPE based on Graphene/ZnCr LDH for Pb(II) analysis in hair samples followed by GFAAS.: This research highlights the application of Supelclean ENVI-Carb II/PSA SPE Tubes in the extraction and analysis of lead(II) ions from hair samples. The tubes significantly improve the efficiency of the sample preparation process, enabling precise and reliable lead quantification using graphite furnace atomic absorption spectroscopy (GFAAS) (Mirzaee et al., 2021).

Solid Phase Extraction: Ion Exchange Methodology

SPE retention mechanism in this case is based on the electrostatic attraction of charged functional groups of the analyte(s) to oppositely charged functional groups on the sorbent.

SPE retention mechanism in this case is based on the electrostatic attraction of charged functional groups of the analyte(s) to oppositely charged functional groups on the sorbent.

Solid Phase Extraction: Reversed-Phase Methodology

Reversed-phase interaction will retain most molecules with hydrophobic character; it is very useful for extracting analytes that are very diverse in structure within the same sample.

Reversed-phase interaction will retain most molecules with hydrophobic character; it is very useful for extracting analytes that are very diverse in structure within the same sample.

实验方案

Solid Phase Extraction: Normal Phase Methodology

Retention occurs through polar interaction between the sorbent and analytes. Typical sample matrices that can be employed in normal-phase SPE include hydrocarbon or fatty oils diluted in a solvent like hexane, isooctane, chlorinated solvent, THF, diethyl ether, or ethyl acetate.
