    Abstract: A rheometer and method of making rheological measurements are disclosed, in which a sample is supported between plates and an alternating movement is applied by a driver, support rod and plate. Force and displacement measurements are taken and the property determined from those measurements. The vibrating signal which is applied is in the form of a frequency sweep signal having a monotonic group delay function. The top plate is provided with a surface which causes a meniscus to form up a side edge of the plate to reduce the spring nature of the sample when the movement is supplied to the sample, and a supporting rod which supports the top plate is preferably formed from a material having a low coefficient of thermal expansion so that the gap between the plates is maintained substantially constant if the sample is heated to take measurements at different temperatures.

    Abstract: A spectrometer is disclosed which comprises a plasma torch and an induction coil for generating a normal plasma within the torch. The torch has an outer tube and an inner tube. If the plasma collapses from a normal plasma state to a toroidal or faulty plasma shape, a photodiode detects the change in shape so that the plasma torch can be shut down to prevent the plasma shape from melting the tube of the torch.
