ESTIMATION OF THE UNCERTAINTY IN THE QUANTIFICATION OF H2, N2, CO, CO2 AND CH4 IN GAS SAMPLES
Ortiz, María Elena
The quantification of H2, N2, CO, CO2 and CH4 in gas samples is a routine analysis performed in our laboratory, according to internationalstandards. All samples contain the five analytes, each one in different concentrations. Estimating uncertainty is important in order to determine thesources of higher dispersion, in accordance to the requirements of NCh-ISO.17025.
