以γ戊内酯为例，使用上述生物质基调和燃料的互溶性测试系统对γ戊内酯和汽油的互溶比例进行测定，步骤如下：
1)向两燃料瓶41内分别导入200体积汽油和200体积γ戊内酯，汽油为基液，γ戊内酯为添加剂溶液，向水浴缸1中注入冷却液，ECU控制装置6控制温控机构12工作并使得冷却液温度达到20℃后，ECU控制装置6控制激光器31开启，激光器31发射的光束经过反光机构32反射至感光机构33的板体上，光敏传感器感应光斑，并通过控制装置标记其位置信号为基点，然后ECU控制装置控制激光器关闭；
2)ECU控制装置控制流量阀开启并向混料罐内注入100体积基液并使得混料罐内基液埋没反光机构，待第二温度检测器检测混料罐内基液温度达到20℃且其平静无气泡状态下，ECU控制装置控制激光器开启，激光器发射的光束经过基液折射后并通过反光机构反射至感光机构的板体上，光敏传感器感应反射机构反射后的光斑，并通过控制装置标记其位置信号为A 0，然后ECU控制装置控制激光器关闭；
