Objective To evaluate the uncertainty of determination of total dissolved solids based on Monte Carlo method. Methods The corresponding mathematical model of the total dissolved solids of solubility was established. According to the Monte Carlo method of distribution and summarization process, the results of the assessment by Monte Carlo method were obtained. The Guide 98-3: 2008 Measurement uncertainty representation guide was used to evaluate and compare. Results The result of using Monte Carlo method was 208.0 mg/L, and the extended uncertainty was 5.2 mg/L. The range was 197.8~218.18 mg/L. The result of Measurement uncertainty representation guide method was 208.6 mg/L, the uncertainty of expansion was 5.6 mg/L, and the calculated result was (208.6 ± 5.6) mg/L. Conclusion The results of Monte Carlo method is similar to the Measurement uncertainty representation guide method, and the Monte Carlo method can be used to calculate the uncertainty of the measured total dissolved solids. It provides a practical measurement uncertainty assessment method for the laboratory staff.
