Determining Volatile Impurities and Ethanol Content in Hand Sanitizers with GC–MS
September 10th 2024Researchers analyzed 31 different brands of hand sanitizers using headspace gas chromatography-mass spectrometry (GC–MS) to assess volatile impurities and ethanol content in ethanol-based hand sanitizers.
Modern HPLC Strategies: Improving Retention and Peak Shape for Basic Analytes
August 16th 2024In high-performance liquid chromatography (HPLC), it is common for bases and unreacted ionized silanols on silica-based columns to cause irreproducible retention, broad peaks, and peak tailing when working with basic analytes. David S. Bell, Lead Consultant at ASKkPrime LLC offers innovative HPLC strategies that can help mitigate such issues.
