- in the range above 16 mg/kg to 46,000 mg/kg                        ± 0.8694 C0,6446
- in the range above 46,000 mg/kg to 50,000 mg/kg                 ± 1,7388 C0,6446
where C is the measured value of the mass fraction of sulfur, mg/kg.

The relative standard deviation of the COE of the random component of the error when measuring the mass fraction of sulfur 500 mg / kg is no more than 0.5%
The repeatability limit of the results of single measurements of the mass fraction of sulfur r (P=0.95), mg/kg:
in the range from 3 mg/kg to 16 mg/kg r=0.8694 C0,6446
in the range of sv. 16 mg/kg to 46,000 mg/kg r=0.4347 C0,6446
in the range of sv. 46,000 mg/kg to 50,000 mg/kg r=1.3041 C0,6446
where C is the measured value of the mass fraction of sulfur, mg/kg.

The theoretical limit of detection in 600 seconds is less than 3.0 mg/kg;
The counting rate on the molybdenum (SU-Mo) installation sample is at least 10000 pulses/s.
The limit of the relative error of the analyzer when measuring the counting rate at SU-Mo is no more than 0.5%
if the following conditions are met:
