What's New at the Largest Liquid-Phase Separations Conference in the World

Mark your calendar to attend HPLC 2020 on June 20-25, 2020 in beautiful San Diego, CA, USA along the dramatic Pacific coastline. The HPLC conference will celebrate its 50th edition in 2020, and has grown to become the largest and most visible...

The Basics of HILIC

How can we describe the mechanism at the basis of HILIC retention? We will answer this question and give you an insight into the main interactions that govern chromatographic separation in HILIC mode.

Do you HILIC?

Are your analytes eluting close to the void volume of a reversed-phase (RP) column? Do you have problems retaining organic molecules under conventional reversed‑phase liquid chromatography (RPLC) conditions? Have you increased the initial percentage...

HILIC & MS

The separation power of HPLC combined with the very high sensitivity and selectivity of MS detection is widely used to develop analytical methods that are required to achieve ultra-low detection and quantification limits. Examples of such demanding...

Sample Solvent in HILIC

The sample solvent, also called dissolution solvent or injection solvent, is the solvent used to prepare the solution in which the compound to be analysed by HPLC is dissolved. The choice of the sample solvent is fundamental for a successful...

Column Equilibration in HILIC

It is matter of fact that the samples most chromatographers have to face are rather complex for sample number and compound variety. In these situations, gradient elution is largely preferred for the separation of analytes with different retention...

Column temperature in HILIC

Mostly in HILIC conditions, by increasing column temperature a decrease in the retention time is observed.

HILIC Mobile Phase: pH

This article discusses the pH of the mobile phase that should be selected in order to enhance the hydrophilicity of the analytes.

HILIC Mobile Phase: Salt Content

In this technical article the effect of the salt content in HILIC mobile phases and the preparation is discussed.

HILIC Mobile Phase: Solvents

In HILIC, small variations of the elution conditions often result in differences in the retention greater than the ones observed in RPLC. Therefore, particular attention has to be paid to the selection and the preparation of the eluents. 

HILIC Stationary Phases

A common and useful classification of the HILIC stationary phases is on the basis of the presence of functional groups on the surface and their charged state: they can be divided in unbounded and bonded phases, and these ones are classified in...

Shodex HILIC tutorial

This video provides a general overview of hydrophilic interaction chromatography, also known as HILIC.HILIC separation is based on hydrophilic interaction. HILIC uses the same solvent as with reserved-phase chromatography (acetonitrile / water /...

New HPLC columns from Shodex to improve your separation performance

Shodex's new range of columns are available for a wide range of separation techniques. The separation techniques start with reversed phase, normal phase, HILIC, ion chromatography, ion exchange, ion exclusion, size-exclusion chromatography,...

Leading the Way to Ensure the Separation Sciences Remain a Powerful Analytical Tool

Mark your calendar to attend HPLC 2018 on July 29-August 2, 2018 in Washington, DC USA. The HPLC conference will celebrate its 47th anniversary in 2018, and has grown to become the largest and most visible international conference series dedicated...
