这句英文，语法有错误吗？

The samples prepared for IR analysis were successively performed a variable-temperature IR measurement.

根据句意，不用加on吧

The samples prepared for IR analysis including a variable-temperature IR measurement, were successively performed

去掉on和were: 加on的话，后面必须再接动作对象，而此时不需要；加were的话表示被动，被动不能直接接宾语，起码再加个介词。而此时根据句意是不需要被动的，所以删掉。

去掉were 还有on
