Rapid method for analysis of nicotine and nicotine-related substances in chewing gum formulations

Abstract Based on environmental requirements and demands for a high throughput a rapid method for the analysis of nicotine and nicotine-related substances in chewing gum formulations was developed. The method is based on sample preparation through liquid–liquid extraction followed by reversed-phase HPLC using gradient elution. It allowed up to nine analytes to be determined within 15 min, including the sample preparation, and was considered as accurate and robust.
