1. Methodological studies:comprehensive method validation and project-specific method validation. Parameters include: accuracy, sensitivity, selectivity,precision (repeatabilityand reproducibility), soundness,specificity, detection limit, quantitative limit, linearityrange, durability, uncertainty of measurement ,pre-experiment and other temporary tests. Methodology validation can also be done as specified by the customer.

2. Method optimization: evaluate the possibility of method optimization through expert evaluation, pre-experiment, etc.;

3. Method validation and laboratory management training
