A simplified version of the Hirst automatic volumetric spore trap has been developed in Derby for aerobiological studies. In comparative trials, the number of spores retained by the Morrow Brown trap were similar in the case of larger spores such as Alternaria (102%), rather higher in the case of grass pollen (136%) and considerably higher (166--201%) for very small spores such as Sporobolomyces and Tilletiopsis. Impaction efficiency has been improved by using a narrower slit. The trap designed in Derby is simple to produce and presents advantages in design over the Hirst version.
德比郡已开发出一种用于空气生物学研究的简化版赫斯特自动定量孢子捕捉器。在对比试验中，对于较大的孢子，如链格孢，莫罗·布朗捕捉器捕获的孢子数量相近（102%）；对于草花粉，捕获数量较高（136%）；而对于非常小的孢子，如掷孢酵母和蒂氏酵母，捕获数量则高得多（166% - 201%）。通过使用更窄的狭缝提高了撞击效率。德比郡设计的捕捉器制作简单，在设计上比赫斯特版更具优势。
