样品浓度：将加有分散剂的水约500ml加到循环泵试样池中，然后加入适量待测样品(约1克)并打开搅拌器和超声波分散器对样品进行搅拌分散约3分钟。配制悬浮液的关键是要掌握好样品的浓度。由于水煤浆的粗细程度，比重、光学特性等都有所不同，所以对不同样品来说悬浮液的浓度也各不相同。一般说来，样品越细，用量越少；样品越粗，用量就越多。悬浮液的浓度终要满足浓度测量时光能分布的要求，一般要求浓度测量是光能分布大值为20--60之间，特殊情况应根据实验确定合适的浓度值。悬浮液的浓度太大或太小对测试都是不利的。浓度过大，颗粒间的相互作用加剧，从而影响正常的颗粒状态；浓度过小，样品代表性差。这些都将对测试结果产生不利影响。
