Presto C8 AQ combines the faster elution profile of a C8 phase with complete stability in 100% aqueous mobile phases. It offers an ideal alternative when analytes exhibit excessive retention on C18 phases.

Presto XP C8 provides robust performance under elevated pH conditions where standard C8 phases degrade. Its advanced core-shell technology ensures sharp peak shapes, lower backpressure, and fast analysis times.

Presto CS C8 combines a surface-charged core-shell particle with C8 chemistry to eliminate peak tailing in basic analytes. It provides fast analysis speeds and excellent LC-MS compatibility for moderately hydrophobic molecules.

Presto Peptide C8 is tailored for biomolecules and peptides that bind too strongly to C18 phases. Its core-shell structure accelerates mass transfer, enabling fast run times with high recovery and sharp resolution.

Presto C8 provides moderate hydrophobic retention, eluting hydrophobic molecules faster than C18 while maintaining high resolution and peak symmetry. It is ideal for high-throughput screening and routine QC workflows.

Presto C30 utilizes long alkyl chain chemistry on core-shell particles (120 Å pore size) to offer enhanced shape selectivity. It is uniquely suited for resolving closely related isomers, long-chain fatty acids, and lipophilic compounds.

Presto Phenyl Hexyl features phenyl ring functionality attached via a hexyl alkyl spacer. It provides unique pi-pi interactions and complementary selectivity to standard alkyl phases for aromatic rings, nitroaromatics, and conjugated systems.

Presto Bi Phenyl incorporates dual-ring aromatic chemistry on core-shell particles. It offers enhanced retention for electron-deficient aromatics, structural isomers, and polar pharmaceuticals that are difficult to separate on C18.

Presto PFP combines electronegative fluorine atoms on a phenyl ring with core-shell efficiency. It excels in separating halogenated compounds, positional isomers, and basic molecules where alternative selectivity is required.

Presto RP Amide incorporates an embedded amide group in the alkyl chain, eliminating silanol interactions and enhancing retention for phenolic, acidic, and hydroxylated compounds.

Presto HILIC utilizes high-purity unbonded core-shell particles to retain highly polar analytes that elute near the void volume on reversed-phase columns. Ideal for LC-MS applications with high organic mobile phases.

Presto CS Phenyl Hexyl integrates a surface charge with phenyl-hexyl chemistry to deliver exceptional peak symmetry for basic aromatic compounds under simple, MS-friendly mobile phase conditions.
