HILIC Plus (Hydrophilic Interactionin Liquid Chromatography)-L3

Ideal for: for variety of analytes including aromatic, polycyclic and unsaturated compounds
The π-π interactions between the electron rich double bounds within the analyte and stationary phase phenyl moieties
Relative retention compared to more hydrophobic phases is reported to increase in the order: aliphatics < substituted benzenes < polyaromatic hydrocarbons ≅ nitroaromatics
pH stability: 1,5 to 7

Separation at PFP stationary phase is controlled by hydrogen bonding along with π-π interactions. This stationary phase may be used to analyze both aromatic and aliphatic analytes.
Significant separationat supramolecular level (ibuprophen, omeprazole with LC-MS)
Delivers High-Resolution separation and low back pressures
pH range stability 1,5 to 7,5
Use for selective analysis of non-halogenated compounds, such as polar compounds containing hydroxyl, carboxyl, nitro, or other polar groups.

Ideal for: Sugars, Sugar Alcohols, Vitamins, Steroids, Anionic Compounds, Oligomers (< 30mer), Hydrogen-bonding compounds
Great stability in Normal and Reversed Phase Mode
pH rangestability 2 to 6,5
Outstanding buffer stability

Ideal for: Compounds with COOH, CO, NH₂, NHR₂ or NR₂ groups, Explosives, Esters and Steroids, Plasticizers
Great stability in Normal and Reversed Phase Mode
pH rangestability 2 to 7,0

Ideal for: Amine and polyamine containing compounds, cough and cold compounds, morphine, drugs of abuse, nucleosides, peptides and peptide maps
Provides sharper peaks
Great pH range stability 2 to 7,5
Phenyl-sulfonic acid bonded phase – phenyl gives some reversed phase character that can be enhanced with METHANOL

Ideal for: separating and analyzing anionic species, such as Sb(III) and Sb(V), in aqueous environmental samples
Common method for protein and peptide separation
Suited to the analysis of smaller organic molecules including nucleotides and organic acids
pH rangestability 1 to 7,5

Ideal for: Polar compounds, adsorption chromatography under normal phase conditions
High loading capacity vs. Other silicas
pH rangestability 1 to 7
Outstanding mechanical stability
Low with metal content

HILIC is intended to apply for polar compounds (Neutral and Ionic)
Ideal for polar drugs and their metabolites (as metabolites are more polar than their drug parents)
Ideal for Mass spectrophotometric detection
Different selectivity than in Reversed Phase Chromatography – as polar compounds are retained with high organic concentration
pH rangestability 1,5 to 7
Increased retention with increasing organic concentration
