Imtakt chromatography column from Japan-Unison UK-Phenyl

Characteristics of chromatographic column

◇ Higher column efficiency

◇ Lower column pressure

◇ More suitable for separating hydrophobic compounds

◇ Multiple fixed phase options

◇ available100%Pure water mobile phase

As is well known, the functional groups between the phenyl bond and the separated substanceπ-There is interaction between electrons.

The phenyl chromatographic column exhibits correlation withC4Hydrophobicity and retention ability of the chromatographic column at the same level, but occurring in the phenyl stationary phase and containingπ-Between solutes of electronsπ-πThe interaction resulted inODSThe chromatographic column has the same retention capacity in the mobile phase. In addition, solutesπ-The local influence of electrons (especially para isomers) can be achieved throughUK-PhenylThe chromatographic column completely separates meta - and para isomers, while usingODSThe chromatographic column cannot be achieved.

In today's chemical industry, the structure of compounds is becoming increasingly complex, and in addition to hydrophobicity, the need for substances separated through interactions is also growing. equalODSWhen the chromatographic column cannot solve your separation problem,UK-PhenylChromatographic columns play a constructive role in opening up new horizons in the field of separation.

Quick detection

utilizeUnisonThe high column efficiency and short column length of chromatographic columns enable rapid and large-scale detection of samples. Many users use10mm、20mmand30mmThe column length chromatography column analysis time is significantly reduced and satisfactory separation is obtained. All lengths of chromatography columns are used3μmSilicone filler. When users are searching for optimization conditions between analysis speed and separation, it is recommended to useUnisonChromatographic column.

Avoid collapse of fixed phase

Traditionally designed for separating polar compoundsODSSilicone stationary phase usually has lower coverage compared to silicone stationary phase. This is very important for avoiding the collapse of fixed phases.

(取决于上下文，如"but"UnisonThe chromatographic column provides low coverageODSFixed phase, due to its three functional components and unique capping technology, which is the chromatographic column fixed phasepH1.5The aqueous phase can also remain stable.

pHWide range of direct sales and high durability

Whether in acidic or alkaline solutions,UnisonBoth chromatographic column stationary phases can maintain high stability and durability.

Unison UKThe unique sealing technology of the series chromatography column ensuresC8Phenyl chromatographic column stationary phaseUnison UK-C18The same applies to chromatographic column stationary phasepHWide range and high service life under acidic or alkaline conditions.

Unique sealing technology

UnisonThe chromatographic column produced using unique capping technology exhibits excellent elution performance for difficult to separate substances such as alkaline compounds. This technology is not only applied toUnison UK-C18Chromatographic column, and also applied toUnisonofC8And phenyl chromatography column.

For the analysis draftpKaAlkaline antidepressants with high values,UnisonAll stationary phases exhibit excellent peak shapes, even when used as variable for liquid chromatography-mass spectrometrypHregulator——Ammonium acetate, still so. This means that separation can be achieved even without using phosphoric acid eluent, which is commonly used for UV detection in liquid chromatography column analysis. This can help you avoid the trouble caused by using inorganic salts.
