DTA + Because of coordinated-module design, the very high degree of resolution and sensitivity of the Robert L Stone Differential Thermal Analysis Systems can be extended to numerous ancillary functions by using the versatile basic components:

+ DT—simultaneous testing of two samples is available in two of the basic systems. + EGA—connections for. Effluent Gas Analysis are provided on all basic systems—interchangeable plug-in Bridge Power Supply and second differential amplifier convert channel two to DTA or EGA at will. + TGA—two unique Thermogravimetric Analysis modules utilize the programmer and recorders of the DTA system. + Controlled Pressure—in ranges from 10"" Torr to 100 psi on both DTA and TGA. + Controlled Atmosphere—either dry gases or condensible vapors may be used to control or to catalyse the reactions. + Programmed Cryogenic—down from ambient to —150°C and back up to 200°C. This supplements the normal ambient to 1550°C temperature rise pattern. +• Other Modules—We invite your inquiries. Ask us about special attachments, and also about Temperature Gradient Furnaces and X-Ray Diffractometer Furnaces.
