HLB Hydrophilic-Lipophilic Balanced

Extracting non-polar to moderately polar acidic, neutral and basic compounds

HLB sorbent is composed of monodisperse N-vinylpyrrolidone-divinylbenzene copolymer resinparticles, with specific mixture of hydrophilic hydrophobic groups, allowing for retention for a wide.

owing to HLB has higher stability and widder pH range thus it can be used as a general- purpose sorbent,especially for extracting analytes from complicated samples such as blood and urine.

– General sorbent, suitable for wide application areas
– Highly wettable, no worry of bed dryness, rare breakthrough
– High recoveries, excellent reproducibilities
– 3 to 10 times higher adsorption capacities and loadabilities than C18- bounded silica gel
-Stable from pH 1 to 14, compatible with most common solvents
