Experiment Results. The results obtained from the two methods are summarized in Tables 1 and 2. The MAX ® 5000XL testing results show good agreement with conventional testing results in the case of free and bound moisture for both products, as well as ash content for the wallboard.. The purity factor equation built into the MAX ® 5000XL determined the purity of the gypsum as % for the ...
