3.2. Purity of Analysis
Size variants were evaluated by SEC-HPLC under the native condition, and the results are shown in Table 2. Notably, the 96-h light treatment and 12-, 24-, 48-, and 96-h heat treatments did not fulfill the relevant quality criteria.
The analysis of the impurities and purity of samples is presented in Table 2.
