| 
| TAN's 10-12 have detailed aspects of DTBP tested in the RSD and have concentrated on their thermal data. In TAN 13 the thermal data that is obtained is discussed.
In the RSD up to 6 samples can be run simultaneously, all are normally run with a standard pressure line and pressure transducer. The pressure line may be modified to incorporate a T-piece or other device to allow, eg, easy pressure release. The pressure line has a burst disc, near the sample cell, to protect the cell from possible rupture. (This is of use particularly for glass cells). The standard pressure transducers are 60 bar / 900 psi limited though they will withstand a 300% overpressure. The system is set to stop test and cool prior to the pressure limit.
It is appropriate if best quality data is required to run at a slow heating ramp. The data illustrated here is from tests at both 4ºC/min and 1ºC/min. If analysis is to be done from pressure data it is likely that ‘high quality’ result is needed and therefore a ramp rate of 1ºC/min or below may be used. |
