The evaluation of an improved wipe-rinse technique for the bioassay of large areas was undertaken due to inherent inadequacies in the cotton swab-rinse technique to which assay of spacecraft is currently restricted. Four types of contamination control cloths were initially tested. A polyester-bonded cloth (PBC) was selected for further evaluation because of its superior efficiency and handling characteristics. Results from comparative tests with PBC and cotton swabs on simulated spacecraft surfaces indicated a significantly higher recovery efficiency for the PBC than for the cotton (90.4 versus 75.2%). Of the sampling areas sites studied, PBC was found to be most effective on surface areas not exceeding 0.74 m2 (8.0 feet 2).
由于目前航天器检测所采用的棉签冲洗技术存在固有缺陷，因此对一种用于大面积生物检测的改进擦拭冲洗技术进行了评估。最初测试了四种类型的污染控制布。一种聚酯粘合布（PBC）因其卓越的效率和操作特性而被选中进行进一步评估。在模拟航天器表面上使用PBC和棉签进行的对比测试结果表明，PBC的回收效率明显高于棉签（90.4%对75.2%）。在所研究的采样区域中，发现PBC在不超过0.74平方米（8.0平方英尺）的表面积上效果最佳。
