一般描述
需要含水培养基。
使用方法：
仅取出所需数量的测试棒，并在使用后立即重新密封容器。请勿触摸试纸区域。将测试棒短暂（约 1 秒钟）浸入测试溶液中。5 秒钟后，将试纸区与色标进行比较。
在过氧化氢存在下，试纸变蓝。QUANTOFIX®-过氧化物检测棒也可用于过氧乙酸和其他有机和无机氢过氧化物的测定。为了测试有机溶剂中的氢过氧化物，在蒸发溶剂后，用一滴水润湿测试区。
参考：
pH 值在 2-9 的范围时，测定的准确度与测试溶液的 pH 无关。用醋酸钠缓冲强酸性溶液，用柠檬酸调节碱性溶液至ph5-7左右。假阳性结果只能由强氧化剂引起。
存储：
避免将测试棒暴露在阳光下和潮湿处。将未开封包装储存在冰箱（+2°C至+8°C）中。开封包装：将容器存放在阴凉干燥处。
