New Sample Prep Products and Accessories

A review of cutting-edge analytical extractions using metal-organic frameworks (MOFs), including a description of what MOFs are, their preparation, principles of use, advantages, and application areas.

Next-Gen Sorbent-Based Extractions with Metal-Organic Frameworks

The application of temperature is frequently employed to enhance analytical extractions, especially with solid samples or volatile analytes. This article explores the role of temperature in analytical extractions.

Columns - Turning Up The Heat: The Effect of Temperature on Analytical Extractions

Sorbent-based extractions using metal-organic frameworks (MOFs) have several advantages, notably selectivity. How do these extractions work, and where are they most useful? We look into the current state of the art.

Next-Generation Sorbent-Based Extractions with Metal-Organic Frameworks

Temperature impacts solubility, diffusion, surface tension, and more. It can potentially lead to solute decomposition. This month we will explore the role of temperature in analytical extractions.

Turning Up the Heat – The Effect of Temperature on Analytical Extractions

Temperature is frequently employed to enhance analytical extractions, especially with solid samples or volatile analytes. Using temperature to enhance analytical extractions continues today with more recently developed techniques, which we explore.

Turning Up the Heat: The Effect of Temperature on Analytical Extractions

A panel discussion on the latest advances and future developments in sample preparation.

Trends and Developments in Sample Preparation

Tony Taylor is Group Technical Director of Crawford Scientific Group and CHROMacademy. His background is in pharmaceutical R&D and polymer chemistry, but he has spent the past 20 years in training and consulting, working with Crawford Scientific Group clients to ensure they attain the very best analytical science possible. He has trained and consulted with thousands of analytical chemists globally and is passionate about professional development in separation science, developing CHROMacademy as a means to provide high-quality online education to analytical chemists. His current research interests include HPLC column selectivity codification, advanced automated sample preparation, and LCâMS and GCâMS for materials characterization, especially in the field of extractables and leachables analysis.

Which key efficiency techniques can maximize your analytical  goals? This instalment of the LCGC Blog begins by describing the principles and optimization of liquid-liquid extraction (LLE).

Inexpensive, Quick, and Selective: Seeking the Holy Grail of Sample Extraction

It is important to develop analytical methods to detect  crude MCHM components in environmental water samples. This article describes two microextractive methods based on solid-phase microextraction (SPME) in fibre format and thin film microextraction (TFME) that were developed and validated for 4-MCHM and other constituents of crude MCHM.

Exploring the Efficiency of Various Extraction Approaches for Determination of Crude MCHM Constituents in Environmental Samples

This article reviews how nanomaterials are being used in a variety of sample preparation techniques, such as dispersive solid-phase extraction (dSPE), solid-phase microextraction (SPME), stir-bar sorptive extraction (SBSE), and matrix solid-phase dispersion (MSPD).
