Simple Analysis of 4-Methylimidazole using Automated Solid Phase Extraction
10 Aug 20164-methylimidazole (4-MEI) is formed as a byproduct in some foods and beverages such as colas, beers, soy sauces, breads and coffee. There has been an increase in concern lately about 4-MEI being a suspected carcinogen, this has led to regulations being put in place on the amount allowed in foods. This application note details a simple method to analyze levels of 4-Methylimidzaole using Automated Solid Phase Extraction.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats.

It is widely used in environmental, pharmaceutical, and clinical analysis. SPE provides higher sensitivity and selectivity compared to traditional liquid-liquid extraction methods, making it essential for accurate and reproducible results.
