A method has been developed for measuring formaldehyde concentrations in a subatmospheric steam-formaldehyde autoclave. Data obtained using this method indicate that the concentration of formaldehyde in the chamber atmosphere is not homogeneous and that it decreases rapidly with time. The penetration of formaldehyde vapour into narrow tubes has also been investigated and was shown to be dependent on the length-to-bore ratio of the tubes. The formaldehyde concentration within the tubes could be increased by using a lower vacuum in the air removal stage at the beginning of the cycle.
已开发出一种用于测量低于大气压的蒸汽-甲醛高压灭菌器中甲醛浓度的方法。使用该方法获得的数据表明，腔室内空气中甲醛浓度不均匀，且随时间迅速降低。还研究了甲醛蒸汽在细管中的渗透情况，结果表明其取决于管子的长度与内径之比。在循环开始时的空气排出阶段采用较低的真空度，可以提高管内的甲醛浓度。
