Trendsetting Technology High-Pressure DSC Measurements Even at Subambient Temperatures In contrast to the setup of a regular DSC, the measuring cell of a high-pressure DSC (HP-DSC) is surrounded by an autoclave which is supported by pressure and gas flow control systems. Pressure and purge gas flow are adjusted via a separate control board (see also next page). With the help of liquid nitrogen cooling, it is even possible to achieve temperature programs in the subambient range. The heating and cooling rates achieved (0.01 K/min to 100 K/min and to 50 K/min, respectively) as well as the...

In some reactions, the atmosphere not only serves for the generation of pressure but is also a reaction partner in the expected solid-gas reaction. Regulation of pressure and gas flow must be particularly precise. Precise Pressure and Gas Flow Control Measurements in different gas atmospheres such as O2, N2, Ar, He, H2, CO2 and CH4 are no problem in the robust measuring cell. The sample atmosphere can be either static or dynamic. The optional electronic pressure control device along with the ability to precisely regulate the purge gas flow are the main features allowing for outstanding...

Versatile Applications Synthetic Oil – Increasing Oxygen Pressure Resulting in Oxidation at Lower Temperatures This graph shows the oxidation behavior of a stabilized synthetic oil (sample mass of 3.0 mg ± 0.1 mg) in aluminum pans at 2 K/min in oxygen (100 ml/min) under defined pressures. As oxygen pressure increases, oxidation begins at lower temperatures (lower extrapolated onset temperature). Polycondensation – Curing Behavior of Phenolic Resins This graph shows the partial area evaluation of the curing effect of two phenolic resin lots (A, B) under a practical pressure of 9 MPa in an...

Precision of the Pressure Control, Dehydration of Iron Oxide Hydroxide 2α-FeOOH → α-Fe2O3 + H2O exo 1.2 Just like decomposition, dehydration reactions are significantly influenced by the pressure applied. This example shows a measurement on a nanocrystalline goethite at a heating rate of 10 K/min. With increasing pressure, the release of gaseous reaction products is shifted to higher temperatures: from 251°C at ambient pressure (not shown here) to 281°C at 150 bar. The pressure variations detected during the dynamic heating segment do not exceed 150 bar ± 0.01 bar (a hundred times smaller...
