The temperature/time profiles specified in Table 11 were achieved with a Fischer Labortechnik 1.5 kW, 1.1 MHz high frequency generator and ferromagnetic wires with a diameter of 0.5 mm. Occasionally, e.g. with relatively volatile compounds, samples were pyrolysed in ferromagnetic tubes ("oven pyrolysis") as indicated in the Atlas. Such oven pyrolysis was performed with pure iron tubes (Curie-point temperature 770°C), with an outer diameter of 1.5 mm, a length of 13 mm and a wall thickness of 0.1 mm. Temperature-rise times achieved are slightly faster than these of the corresponding ferromagnetic wires.
