A dry-heat oven with automatic, multiple-sample introduction and withdrawal has been constructed to achieve instantaneous heating and cooling of samples. The oven temperature fluctuation at set points of 170 to 250 degrees C was +/- 0.1 degrees C, with temperature variation between the replicate samples of +/- 0.2 degrees C. Correction required for a sample come-up time was minimal, i.e., less than 0.25 min of the dry-heat destruction time.
已构建了一台具有自动多样品进样和取出功能的干热烘箱,以实现样品的瞬时加热和冷却。在170至250摄氏度的设定点下,烘箱温度波动为±0.1摄氏度,重复样品之间的温度变化为±0.2摄氏度。样品升温时间所需的校正极小,即小于干热破坏时间的0.25分钟。
