FROM SILICA TO COLUMNSWe have been producing, modifying and coating silica for many years. To deliver the best HPLC columns to customers we have modern equipment and demanding quality control at each of the diff erent production stages at the manufacturing and R&D sites in India and Sweden. Moreover, our long experience and knowledge in silica chemistry guarantees high quality and excellent batch to batch reproducibility.

SILICA PRODUCTION AND FUNCTIONALISATIONWe make spherical porous silica particles with controlled pore size, particle size, and par-ticle size distribution resulting in excellent chromatographic properties. The SEM (Scanning Electron Microscope) image below shows perfect spherical shapes and narrow particle size distribution with no fines or crushed particles. The magnified image shows perfectly smooth silica surfaces with no irregularities.

We offer a range of phases with different and complementary chromatographic properties. We perform the functionalisation at our production laboratory using proprietary production protocols to produce densely functionalised and end capped silica particles with low residual silanol activity/acidity. The result is particles with excellent chromatographic performance and exceptional chemical stability.

SELECTIVITY COMPARISON (TANAKA TEST)To fully characterize surface properties of the chromatography media the Tanaka test is used. It is an established method to evaluate interactions between a stationary phase and different kinds of analytes. Depending on the analyte, different properties of the stationary phase, like hydrophobicity, ion exchange capacity, steric selectivity, and hydrogen bonding are evaluated.

The tests and analytes used are summarized below:

Analysis conditions: Mobile phase: 1. CH3OH/H2O = 80/20 (v/v) (HR, HS and SS) 2. CH3OH/H2O = 30/70 (v/v) (HBC) 3. CH3OH/20 mM potassium phosphate buffer = 30/70 (v/v) (IEX at pH 2.7 and 7.6); Flow rate: 1 mL/min; Column temperature: 300C; Detection: UV 210 nm; Injection volume: 5 µL

HR/5 (retention factor) – describes the hydrophobic retention of the stationary phase and is measured using the retention factor of pentylbenzene divided by five (5).

HS (hydrophobicity or hydrophobic selectivity) – is the selectivity factor between alkylbenzenes which differ by one methylene group (pentylbenzene and butylbenzene). It provides measurement of the functional groups density.

SS (steric selectivity) – is the ability of the stationary phase to dis-tinguish between molecules with similar structures and hydrophobi-city, but with different shapes like o-terphenyl and triphenylene. The former has the ability to twist and bend, whereas the latter has rigid and flat structure.

HBC (hydrogen bonding capacity) – provides a measure of the number of available silanol groups and the degree of end capping by measuring the selectivity between phenol and caffeine. A low value indicates that the stationary phase has low number of silanol groups available to hydrogen bond with caffeine, and thereby gives a measure of the HBC of the silica surface.

IEX pH 7.6 (total ion exchange capacity) – is the measure of the total silanol activity on silica surface at pH>7 when the residual silanol groups are deprotonated and the amine is protonated (pKa = 9.3). It is estimated by the selectivity factor between benzylamine and phenol.

IEX pH 2.7 (acidic ion exchange capacity) – is estimated by the selectivity factor between benzylamine and phenol, at pH 2.7. At pH

Since the Tanaka test consist of six independent test runs, the best way to look at the results and compare them is to plot the data in Spider web charts (see below). Each axis starts in the centre of the diagram and belongs to one test.

• General fi rst choice column

• High hydrophobic retention

• Wide range of analytes

• Excellent peak shape for acids and bases

Kanak C18 is the fi rst-choice LC column for a wide range of analy-tes. The high carbon load ensures high retention and selectivity for compounds with moderate to high lipophilicity. Thorough end-cap-ping together with very low acidity and homogenously distributed residual silanol groups gives excellent peak shape and effi ciencies with bases as well as acidic compounds.

Kanak C18 will experience reduced ligand cleavage at low pH due to extremely inert silica and high ligand density, providing excellent stability with acidic buff ers.

Bonded Phase : Dimethyloctylsilane

End-Capping : Yes

pH Range : 1-9

• Similar selectivity for lipophilic compounds as C18

• Lower retention than C18

• Slightly diff erent selectivity for ionized acids and bases compared to Kanak C18

• Excellent peak shape for acids and bases

An alternative media to Kanak C18 that will give lower retention. Due to the more hydrophilic nature of the bonded phase, ionized acids and especially bases can have better peak shapes and slight-ly diff erent selectivity compared to Kanak C18. Good choice for mixture containing both moderately polar and very hydrophobic compounds.

• Good choice for mixture of aromatics and/or polar protic analytes

The electron rich phenyl ring and the alkyl chain will give a mixed interaction; π-π and hydrophobic interaction, respectively. The π-π interaction is most pronounced with electron defi cient aromatics and protic moieties, such as hydroxyl groups. Good choice as an orthogonal column compared to Kanak C18/C8 in method deve-lopment, where the traditional alkyl-based stationary phases fail to provide adequate separation.

This media can successfully be used in highly aqueous conditions (100 % wettability), providing an excellent media for very polar compounds.

Kanak PFP



Pore Size : 110 Å


Carbon Load : 7%


Bonded Phase : Dimethylpentafl uorophenylpropylsilane

End-Capping : Yes

USP Code : L43

pH Range : 2-8

• Strong retention of protic compounds and analytes with high dipole moments

• Strong π-interaction with electron rich phenyl rings• Outstanding shape selectivity

Due to the highly electron defi cient nature of the aromatic rings of Kanak PFP, the stationary phase will interact strongly with analytes containing polar aprotic and electron rich aromatic moieties. This contrasts with the Kanak Phenyl Hexyl stationary phase.

Additionally, the electronegative fl uorines of the pentafl uorophenyl group will provide strong hydrogen bonding with analytes with protic moieties, such as hydroxyl groups and carboxylic acids. Furthermore, the delocalized charge over the fl uorine-carbon bond will interact with analytes containing dipole moments. Thus, Kanak PFP will give diff erent selectivity compared to Kanak Phenyl Hexyl.

The polar nature of Kanak PFP ensures a fully wettable stationary phase, enabling Kanak PFP to analyse very polar compounds.

The strong hydrogen bonding of the PFP column is clear from the above comparison with C18. The hydrogen bonding acceptor, caff eine, and the donor, phenol, has much higher retention than for the C18.

• Very polar stationary phase

• Strong dipole-dipole interactions

• Orthogonal phase in RPLC method development

• Good choice for HILIC and NP

A good choice for analytes having too high retention on an alkyl-based stationary phase, as well as mixtures of very polar and lipophilic analytes. The nitrile group of the stationary phase interacts favourably with analytes containing double and/or triple bonds, thereby making Kanak Cyano optimal for unsaturated compounds.

Due to the very polar nature of the Kanak Cyano bonded phase, it can be used in both HILIC-mode as well as in normal phase chromatography.

• Excellent stability

• Proprietary coating ensures solely hydrophobic interaction

• Unparalleled peak shape for ionisable compound

• Low bleeding

Kanak C18 Plus is coated with a proprietary bonding technology, which ensures a fully covered silica surface. The column material is thereby protected against hydrolysis of the ligands at low pH and silica dissolution at high pH. Furthermore, the complete coating will give only hydrophobic interactions, which will give unparalle-led peak shape for all types of analytes.

The proprietary bonding technology binds the ligands strongly, providing exceptionally low bleeding.

Kanak Core

KANAK CORE Kanak Core is a core shell product which consist of a solid core particle coated with a layer of porous silica, as illustrated below. A key feature of core shell columns is the much narrower particle size distribution compared to the fully porous materials for a comparable particle size so that the space among particles in the column reduces and efficiency increases. Usually, columns packed with 3 μm core shell particles produce efficiencies approaching those packed with 2 μm fully porous particles, but at significantly lower back pressures.

Kanak Core offers:

• Exceptional peak shape for basic, acidic and chelating compounds

• High stability at low and high pH (1-10)

• Excellent back pressure profile
