the measurement will be terminated in one minute, around 0.01%. Therefore, more accurate results will be obtained if the measurement time is preset in the “Timing Mode.” The measurement conditions should be the same each time.(2)In the event that the absolute value of the measurement results is different from those of a Karl Fischer moisture analyzer, it is possible that a constituent other than water is vaporizing. It is recommended that the drying temperature and measurement time are set so that there is a correlation between the results of the two methods.To correlate the results of the MS70 with those of a Karl Fischer moisture analyzer, conduct both measurements in the same location simultaneously. Depending on the storing environment, the samples may absorb moisture (See the measurement results in Graph 3).(3)When the moisture content reaches below 0.1%, the influence of errors by the moisture analyzer become more significant, not to mention that of environmental factors (humidity). For instance, a moisture content of 0.02% means that a mass change of 0.004g has to be detected when the sample mass is 20g (and only a 0.001g mass change for a 5g sample mass). Therefore, the larger the sample mass the more accurate the measurement.(4)When measurements are done in succession, the temperature around the sample pan increases, which volatilizes some of the sample’s moisture before starting a subsequent measurement, thereby causing more errors. It is highly recommended that a cooled pan be used each time and that measurementintervals of approximately 10 minutes be taken to lower the temperature around the pan and maintain an equal temperature distribution for each measurement.
