Several factors can impact data accuracy in catalytic studies: - Instrumentation: The precision and calibration of analytical instruments like HPLC, GC-MS, and spectrophotometers. - Experimental Design: The rigor and robustness of the experimental setup, including control variables and replication. - Sampling Techniques: Methods used for collecting samples, which must be consistent and representative. - Data Processing: The algorithms and software used for data analysis, including error correction and statistical treatment.
