Do you suffer from protein aggregation, oligomerization or degradation? If so, analytical SEC is a great diagnostic tool... 

Looking for an LC system that can improve your analytical, instrumental, and laboratory efficiency? If so, find out more about the Agilent 1260 Infinity II Prime LC...

Tired of dedicating methods to LC instruments? With the Agilent 1260 Infinity II Prime LC and Intelligent System Emulation Technology (ISET) you can run methods from your older Agilent, Waters, or Shimadzu LC systems without disruption.

If the answer is yes, take a look at the 'BlendAssist' function of the Agilent 1260 Infinity II Prime LC. With this you can reduce manual work during method development, and eliminate the waste and storage of premixed mobile phases. Watch the video...

Silica- and agarose-based resins are the two most used types of size exclusion chromatography (SEC) resins available for protein analysis purposes. But how do they compare and which should you use?

The OMNIS Sample Robot from Metrohm meets the need of petrochemical laboratories for automated TAN/TBN determinations in large numbers of samples.

Completely unattended volumetric water determination in up to 50 samples is now possible with the OMNIS Sample Robot from Metrohm.

The new OMNIS Karl Fischer titrator stands for a safer and more convenient way of volumetric water content determination.

This video provides a general overview of size-exclusion chromatography.Size-exclusion chromatography is used for analysing high molar mass compounds, such as synthetic polymers, bio-polymers, like proteins and antibodies, polysaccharides and other...

The LC-UV method shown in this application note from Restek uses a Raptor ARC-18 column to fully resolve 16 major and most frequently observed minor cannabinoids for which commercial standards are available.

This video provides a general overview of ion chromatography.

The IC separation is based on electrostatic interaction (bonding) between the ion exchanger and ionic solutes. Different columns for anionic and cationic separation are available. The...

Analysts have long enjoyed the benefits of Merlin Microseal septa for their traditional and SPME fiber injections—and now, you can switch to these innovative septa for your SPME Arrow applications, too!

Water content determination is a standard application in many samples and Karl Fischer titration is the most widely used and accurate method. Metrohm offers solutions enabling the water content determination in almost any matrix ranging from solid...

This video describes the separation mode of ligand exchange (LEX). The main application is the complex analysis of sugars. The LEX columns always have a double separation mode. This means two different separation modes in one column. Ligand exchange...
