High Speed Determinations
Another useful feature of the CAL3K Calorimeters
The high speed operation is the result of a couple of innovations:
- The stainless steel mass is less in relation to the heat sink (aluminium sleeve). A 25% reduction was achieved.
- New Firing Conditions. The wait time before firing is reduced by a "predictive" initial vessel temperature algorithm which allows the early firing of the sample.
- The results can be predicted in the fast mode due to the increased stability of the vessel temperature sensing. The new vessel has a 5ppm stability, which is about 100 times better than the older vessel.
- The close tolerance of the ATC (Automatic Temperature Control) jacket temperature. The jacket temperature is regulated to within 0.1°C to match the target setting, thus making the temperature losses (or gains) very precise. This aids the determination speed because the vessel temperature is predictable.
