Here the mass contribution of the three different types of water is clearly seen. Mass gain versus time following reheating at 500°C (a) the characteristic two stage mass gain.

This is the combined mass gain of all the three types of water identified T0 T1 T2 (~27,000 data points).

t¼ plot shown in Figure 3 when the data are acquired at temperature T.

Further ya is defined as: It follows that the age of the sample (ta) is: These relationships are illustrated in Figure 4.

The contribution these components make to the overall mass can be separated out as shown by graphs (b) and (c) (b) mass gain due to T0 T1 only and this eventually stops when the sample has equilibrated with the ambient conditions.

This mass will track any changes in temperature or relative humidity.

This can only be achieved by maintaining constant conditions of temperature and relative humidity.

Wilson et al described the procedure for RHX data in detail.

Mismatch of balance resolution to sample mass results in large variation in combined relative uncertainties, which vary by four orders of magnitude (approx.
