No, the analytes Theobromin, theophyllin, theaflavins and theanin is missing. I guess Theobromin and theophyllin could be detected with this method. For Theaflavins and Theanin two different methods will be necessary

yes

yes

NO "regarding precautions refer to the corresponding safety data sheets for each individual reagent"

Yes
