    Derivatization Reagents: For Selective Response and Detection in Complex Matrices

    Derivatization is a commonly used technique to augment chromatography analysis. It requires efficient and effective reagents that can modify the behavior of complex compounds and allow their detection in chromatographic analysis. Since the release of the last Derivatization guide in 2009, several innovative derivatization reagents have been introduced for various detection methods, and many other ...

    Molded Thermogreen LB-2 Septa

    Injection port septa used in gas chromatographic analyses should exhibit low bleed, resist leaks, and be easy to penetrate. For years, Thermogreen LB-2 septa have been considered by many as the benchmark GC septa for these parameters due to several performance advantages over other commercially available septa. A new generation septum, molded Thermogreen LB-2, continues the Supelco tradition of ...

    Radiello® Manual (PDF 1766 KB)

    In pumped sampling the adsorbed compound behaves as a chromatographic peak (top): air flow displaces it along the adsorbent bed and its concentration is distributed as a gaussian function. Eventually, the compound comes out from the opposite end. When its concentration in the outlet air is 10% of the concentration in the sampled air we say that the breakthrough has been reached or, with a ...

    Solid Phase Extraction Products: Improve Sensitivity and Increase Throughput

    Solid phase extraction is a form of digital (step-wise) chromatography designed to extract, partition and/or adsorb one or more components from a liquid phase (sample) onto stationary phase (sorbent or resin). Over the last twenty years, SPE has become the most powerful technique available for rapid and selective sample preparation (prep) prior to analytical chromatography. SPE extends a ...

    Formaldehyde and Acetaldehyde Determination in Air Using Fully Automated On-Line Desorption and Analysis of DNPH Cartridges

    Airborne aldehydes and ketones are collected by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH). Carbonyl compounds react with the DNPH to form hydrazones, which are immobilized on the cartridge. These compounds can be easily eluted from the cartridge with acetonitrile and analyzed by HPLC with UV detection. Traditionally, this analysis including the workup contains a ...

    GC Column Selection Guide

    An optimized chromatographic separation begins with the column. The selection of the proper capillary column for any application should be based on four significant factors: sationary pahse, column I.D., film thickness, and column length. The practical effects of these factors on the performance of the column are discussed briefly on this document, in order of importance. Note that this ...

    Determination of Additives in Beverages Using Ascentis® Express Columns

    Beverages, such as sodas and energy drinks, can include a number of polar ingredients, which are easily soluble in the water matrix of the drinks. These ingredients include sweeteners (sugars and sugar substitutes), caffeine, vitamin supplements, amino acids, organic acids, and plant extracts. Because the analytes are already in solution, there is no need for extensive sample preparation. ...
