Liquid Chromatography

Join this ICP-OES focused webinar to learn about new sample introduction components that can enhance analysis of challenging samples with improved productivity, better performance, and simpler maintenance routines.

The sensitivity of a chromatographic method might be described by its limit of detection (LOD). LOD is usually defined as the minimum detectable amount or concentration of a component that can be reliably detected using a given analytical method....

Adsorbent SPME fibers with Carboxen^® or divinylbenzene (DVB) coatings on a Nitinol core have been introduced. In the provided study, the Nitinol core fibers show an improved reproducibility and mechanical stability vs. their predecessors on fused...

This article from Issue 10 of the Analytix Reporter, produced by Merck, describes a unique stationary phase for improved retention and analysis of polar compounds and examples of its applications in food and clinical analysis.

The mobile phase in HPLC strongly influences the chromatographic separation. Its preparation can be a source of trouble for a method, if not done correctly and consistently. This article provides some suggestions and practical tips for the mobile...

Separation Science offers a series of learning modules covering basics, best practice and troubleshooting in GPC/SEC. This multipart series covers such topics as:

Pittcon has been a face-to-face conference and exposition for 71 years, and it is their 72nd installment that they have decided to boldly embrace this ever-changing age. This March 8 – 12 will mark an historic transition reflective of the times:...

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...
