Now the Du Pont TA system can talk with computers and has flame ionization detection capability. This is the new Du Pont 916 Thermal Evolution Analyzer (TEA), an instrument engineered by Carle Instruments, Inc., which has been modified to operate with the Du Pont Thermal Analysis Systems. The 916 TEA utilizes a hydrogen flame ionization detector for organic carbon determination. Its high sensitivity (up to 100 times more sensitive than TGA) makes it ideal for ecology and pollution studies, for determination of polymer additives and for thermal stability studies. It is also capable of making vapor pressure measurements.
This is the Du Pont 990 Thermal Analyzer. The TEA module plugs into it (or the 900 model), as do all modules of the Du Pont TA System, including the new DSC Cell Base which features: 1. Sensitivity of 0.01 mcal/sec/in. 2. Constant calorimetric sensitivity. 3. Derivative DSC data.
This is the new Du Pont 915 Computer Interface (shown with acoustic coupler on top). It lets all the other Du Pont modules "talk" to any on-line time-shared computer. That means data from TMA, DTA, TGA, DSC, Pressure DSC and TEA can be fed into a computer, which can perform complex mathematical manipulations in moments. The 915 plugs into either the Du Pont 900 or 990 Thermal Analyzer. No modifications are needed. It also has provision for six additional inputs to allow for utilization of other equipment in the lab. Computer programs are offered with the Du Pont 915 Computer Interface.

This is the teleprinter that communicates with the computer, or gives you a tape to feed into a computer later. It also prints out the processed data automatically.
The addition of these new modules is further evidence of Du Pont's continuing program to keep its Thermal Analysis System the most complete and useful system commercially available.
