What is hypersil column?

Hypersil APS columns are a versatile aminopropyl group stationary phase which can be used in 3 modes: ion chromatography (weak anion exchanger), reversed phase and normal phase chromatography.

What is a HPLC column?

How Does HPLC Work? HPLC is a highly improved form of column chromatography. A pump forces a solvent through a column under high pressures of up to 400 atmospheres. The column packing material or adsorbent or stationary phase is typically a granular material made of solid particles such as silica or polymers.

What is a C18 column?

C18 columns are HPLC (high performance liquid chromatography) columns that use a C18 substance as the stationary phase. C18 simply means that the molecules contain 18 carbon atoms, so the other atoms in the molecule can vary, leading to significantly different substances.

What is the difference between hypersil ODS and BDS?

The key difference between hypersil and inertsil column is that hypersil column is the trade name for BDS column whereas inertsil column is the trade name for ODS column. Hypersil column or BDS column is a type of reverse-phase HPLC column which has blocked –OH groups.

Why is HPLC used?

The purpose high performance liquid chromatography (HPLC) analysis of any drugs is to confirm the identity of a drug and provide quantitative results and also to monitor the progress of the therapy of a disease.

What is Octadecylsilyl column?

Products/Services for Octadecylsilyl Silica Gel HPLC Columns. HPLC Columns – (163 companies) High performance liquid chromatography (HPLC) is a separation technique that uses liquid mobile phase to separate the components of a mixture.

What is Endcapping in column?

In chromatography, endcapping refers to the replacement of accessible silanol groups in a bonded stationary phase by trimethylsilyl groups. End-capped columns have much lower residual silanol group activity compared to non-endcapped columns.

What is hypersil BDS C18 column?

Hypersil BDS C18 media is an excellent reversed phase material for a variety of applications and is one of the most popular packing materials available. Hypersil BDS columns are a good choice for QA/QC labs as a robust general purpose column in applications where reproducibility and long column lifetimes are required.

What is the surface area of a syncronis column?

Each batch of Syncronis silica is tested for its pore size and surface area using liquid nitrogen adsorption. Syncronis columns are based on highly pure 100 Å silica, with a surface area of 320 m2/g, compared to 200 m2/g for typical silica based material.

Why choose syncronis HPLC columns?

Predictability you can count on, it’s a beautiful thing. Syncronis HPLC columns are available in a range of chemistries to give reproducible separations in reversed phase, HILIC and normal phase chromatography. 4 Testing and Quality Control Silica Characterization

What is the particle size of syncronis silica?

Each manufactured lot of Syncronis silica is tested for its particle size and distribution using a laser particle size analyser. Three particle sizes are available: 1.7 μm for rapid UHPLC separations plus 3 μm and 5 μm for the more traditional HPLC analysis.
