Tips for Operating UHPLC Instruments and Columns
In ultrahigh-pressure liquid chromatography (UHPLC) the UHPLC instrument components must be carefully matched in performance with columns to achieve the desired resolution. If UHPLC underperforms, it can be difficult to determine whether the instrument or column is the problem. This article will describe the design of modern UHPLC instruments and offer simple procedures to identify the causes of poor column and method performance. Modern textbooks do not yet adequately address the complex topic of UHPLC, therefore the reader is encouraged to collect all references to learn important, additional details. More... |
| A Simple, Rapid Automated Method for Determining Total Extractable Fat Using Pressurized Liquid Extraction (PLE) |
Regulating fat content is essential to maintaining the quality of food and feed products. The food industry extracts total fat from food samples to analyze for Persistent Organic Pollutants (POPs). Traditionally, performed by time consuming Soxhlet extraction. Pressurized Liquid Extraction, performs the process in minutes resulting in reduced solvent and higher throughput.

Electrical Potential as a Driving Force in Sample Preparation
To achieve lower detection limits and better selectivity, researchers are always exploring new ways to enhance sample preparation and separation technology. The addition of electrical potential to existing technologies or for entirely new approaches is relatively unexplored but can create another dimension of selectivity in sample preparation. This instalment of “Sample Preparation Perspectives” from Ron Majors looks at the use of electroenhancement to solid-phase extraction, solid-phase microextraction, and membrane and liquid extraction.
