It is studied in this work that this instrument can be used for the analysis of powder cement samples, to deter-mine MgO, Al2O3, SiO2, K2O, CaO and Fe2O3. An estimation for the error caused by sampling is given as an ini-tiative work.

• 作者用该仪器分析了粉末状水泥中MgO、Al_2O_3、SiO_2、SO_3、K_2O、CaO和Fe_2O_3等组成；并对水泥生料的取样误差作了估计.
