 Alert Level A:



DIFF_019  Alert A _diffrn_standards_number is missing                           
          Number of standards used in measurement.                              

DIFF_020  Alert A _diffrn_standards_interval_count and                          
          _diffrn_standards_interval_time are missing. Number of measurements   
          between standards or time (min) between standards.                    

DIFF_022  Alert A _diffrn_standards_decay_% is missing                          
          Percentage decrease in standards intensity.
