Internal standards are crucial in catalytic studies for several reasons:
1. Compensating for Variability: Experimental conditions such as temperature, pressure, and catalyst loading can vary slightly between runs. Internal standards help normalize these variations. 2. Improving Accuracy: By comparing the response of the target analyte to that of the internal standard, researchers can achieve more accurate quantification. 3. Instrumental Calibration: Instruments like Gas Chromatography (GC) and High-Performance Liquid Chromatography (HPLC) can have fluctuating performance. Internal standards help calibrate the instrument's response.
