A method determines measurement data of samples by using a rotation rheometer and a linear DM(T)A analysis unit. The rotation rheometer has units for measuring and/or adjusting the normal force exerted by or on the measurement shaft and/or the speed, deflection angle and/or torque of the measurement shaft. The linear DM(T)A analysis unit has units for measuring the tensile and/or pressure force and/or the position and/or the feed movement of its adjustment rod. The sample to be examined is arranged between opposite measurement parts. Accordingly, the rotational forces or torques transmitted via the sample from the measurement shaft to the adjusting rod, when obtaining measurement data with the linear DM(T)A analysis unit, and, when obtaining measurement data by the rotation rheometer, for the tensile or pressure forces or linear adjustment forces transmitted via the sample from the adjustment rod to the measurement shaft are compensated for. |

1. A method for determining measurement data of samples, which comprises the steps of:
providing a rotation rheometer and a linear DM(T)A analysis unit, the rotation rheometer having units for measuring and/or adjusting a normal force exerted by or on a measurement shaft and at least one of a speed, a deflection angle or a torque of the measurement shaft, the linear DM(T)A analysis unit having an adjustment rod and units for measuring at least one of a tensile force, a pressure force, a position or a feed movement of the adjustment rod, the measurement shaft of the rotation rheometer being rotatably mounted in a bearing, and the adjustment rod of the linear DM(T)A analysis unit being linearly movably mounted in a further bearing; disposing a sample to be examined between opposite measurement parts including a first measurement part supported by the measurement shaft and a second measurement part supported by the adjustment rod; and compensating for rotational forces or torques transmitted via the sample from the measurement shaft of the rotation rheometer to the adjusting rod of the linear DM(T)A analysis unit, when obtaining measurement data with the linear DM(T)A analysis unit, and, when obtaining measurement data by the rotation rheometer, for the tensile force, the pressure force or linear adjustment forces transmitted via the sample from the adjustment rod to the measurement shaft during a determination and/or analysis of the measurement data. |
