| Abstract: | Based on JJG1059-1999,the uncertainty of detection limit of carbon with direct reading spectrometer was assessed.A,the same time,the various factors which effect the uncertainty of measurement were analyzed. Then,the expanded uncertainty was obtained by calculation:u = 0.0011%,k = 2. |
| Keywords: | Direct reading spectrometer Carbon Limit of detection Uncertainty |
