Supelco introduces the SupelTM Tox line of SPE products for sample clean-up prior to mycotoxin analysis. Mycotoxins are secondary metabolites produced by fungi; they elicit toxic effects in humans and livestock. As mycotoxin awareness and government regulations increase worldwide, allowable toxin levels continue to decrease. For quantitative mycotoxin analysis, HPLC and GC are among the most accurate and widely used techniques. The accuracy of the analysis method is highly dependent upon the removal of sample matrix interferences. Therefore, sample preparation is essential for quantitative mycotoxin analysis. With Supel Tox SPE products, the purification is accomplished in fewer steps, with better reproducibility and higher sample throughput.
