3 Reliability
Figure 3.1 and Figure 3.2 showed the temperature reliability testing results of fives DTR2000 portable Raman spectrometers. The testing temperature range was from 5 oC to 40 oC. The spectrometer was kept more than 1 hour at every temperature spots. Acetonitrile was used as the standard sample in the testing. The testing results were calculated using 918 cm-1 of acetonitrile. The wavenumber shift was 1 cm-1 or less(as show in Fig. 3.1). The peak intensity variation was less than 10% (as show in Fig. 4).
