4) Sorbent Selection Guide by Target Compound Type

Target Compound Type	Recommended Sorbent(s)	Retention Mechanism	Typical Sample Types	Notes
Non-polar compounds (e.g., pesticides, PAHs, steroids)	C18, C8	Hydrophobic interaction	Water, serum, urine, plant extracts	C18 offers stronger retention than C8; ideal for reversed-phase cleanup
Moderately polar compounds (e.g., phenols, mycotoxins)	C18, Polymeric RP (e.g., PS-DVB)	Hydrophobic + π-π interaction	Food, biological fluids	Polymeric sorbents are more water-wettable, suitable for polar solvents
Highly polar compounds (e.g., organic acids, catechols)	HLB, NH₂, Diol	Hydrogen bonding, dipole-dipole	Urine, environmental water	HLB retains a broad range; NH₂ useful for weak anion exch. or polar groups
Weak acids (e.g., carboxylic acids, ibuprofen)	SAX, NH₂	Anion exchange	Plasma, pharmaceutical	SAX strongly retains acidic groups; pH optimization required
Weak bases (e.g., amines, alkaloids, β-blockers)	SCX, CM, Cation-Exchange HLB	Cation exchange	Plant extract, drugs in serum	SCX retains positively charged species; elution with NH₄OH or MeOH
Neutral small molecules (e.g., caffeine, parabens)	C18, Polymeric RP	Hydrophobic	Beverage, urine, cosmetics	Use mild elution to avoid co-extracting matrix
Aromatic compounds (e.g., benzene derivatives, flavonoids)	GCB, Phenyl	π-π interaction	Tea, herbal extracts, soil	GCB excels at planar aromatic removal; may adsorb target-test recovery
Sugars, sugar alcohols (e.g., glucose, mannitol)	Amine, Diol	Normal-phase	Beverage, fermentation broth	Not ideal for reversed-phase; use in NP or HILIC mode
Peptides / proteins (cleanup purpose)	C18 (for peptide), GCB (for protein removal)	Size exclusion / interaction	Serum, plasma	Use protein precipitation prior to SPE for better recovery
Hormones & endocrine disruptors (e.g., estradiol, BPA)	HLB, C18, CN	Hydrophobic, mixed-mode	Environmental water, cosmetics	HLB provides broader range capture for trace organics
Pesticides (polar & non-polar)	C18, GCB/PSA combo, QuEChERS + SPE	Multi-mode	Fruit/vegetables, grains	Use multi-layer or tandem SPE for complex matrix cleanup
