used for PCA plotting. Hierarchical cluster analysis (HCA) was then processed based on the results of PCA plot. Results HPLC assay development and validation The constitution of the mobile phase was firstly optimized. Because some of the active
constitution and properties of these catalysts, their Mo 3 d 5/2 , V 2 p 3/2 , Te 3 d 5/2 and P 2p binding energies were investigated with the results listed in Table 1 .
The Mo 3 d 5/2 peak of the catalysts could be fitted into two components at
