Liquid Chromatography

Interferences exist in every chromatographic analysis whether they are recognized or not. Interferences can be visible in your chromatogram and present themselves as reduced peak area counts, split peaks, shoulders around the peak, or peak...

A successful chromatographic analysis starts with the sample. Sample selection, collection, transportation, preservation, storage, and sampling protocol are all aspects of testing that need to be considered in the context of your analytical...

While food and beverage imports and exports continue to increase, regulating bodies are taking a greater interest in these activities that can affect public health. Since the early 2000s, worldwide food imports have increased dramatically, as...

In the last column, we discussed ‘just enough’ sample preparation techniques, such as filtration, protein precipitation, extraction partitioning, solid-supported liquid extraction and QuEChERS. Now we will discuss when ‘just enough’ is not enough...

We’ve covered many of the types of sample preparation options available to make samples ready for instrumental analysis by gas or liquid chromatography and mass spectrometry detection. There are techniques such as QuEChERS, liquid-liquid...

QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) is a sample preparation technique used primarily in the food industry to extract and clean up samples for instrumental analysis. Originally, the QuEChERS approach was developed for...

This technical article shows how sample preparation is an integral part to successful chromatographic analysis and how selecting the right sample preparation technique is dependent upon a number of factors.

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!

This November in Singapore, Separation Science in collaboration with sample preparation expert Ronald Majors, will be providing a one-day training course on sample preparation starteges for good chromatography.
