This capillary begins right on top of the sample inside the TGA furnace to maintain the maximum integrity of the evolved gas. The capillary can be heated up to 200 C to keep the evolved gas from condensing. The resolution is usually set at one mass unit. For example, the difference between the 16 O and 18 O in ordinary water is easily seen. The software for the MS is relatively easy to use and does permit full integration of the MS into the TGA autosampler sequence.
Training is available for both instruments.
Each user is responsible for having their own compatible crucibles. These crucibles can be cleaned and reused many times. Current recharge rates for usage of TGA-MS can be found here .
