Several alternatives can complement or replace grab sampling in catalysis: - In-situ Monitoring: Techniques like infrared spectroscopy (IR) or Raman spectroscopy that provide real-time data without the need to extract samples. - Automated Sampling Systems: Devices that automatically collect and analyze samples at predefined intervals, reducing the risk of human error and contamination. - Continuous Flow Reactors: Systems where the reaction mixture flows continuously, allowing for constant monitoring and adjustment of reaction parameters.
