| 产品名称 : | PLM117 | 纺织品 甲醛的测定 双甲酮醇溶液 GBT 2912.1-2009 |
| 产品品牌 : | 飞净 PHYGENE |
原理:试样在40℃的水浴中萃取一定时间,萃取液用乙酰B酮显色后,在412nm波长下,用分光光度计测定显色液中甲醛的吸光度,对照标准甲醛工作曲线,计算出样品中游离甲醛的含量。
本部分适用于任何形式的纺织品。
本部分适用于游离甲醛含量为20mg/kg到3500mg/kg之间的纺织品。检出限为20mg/kg。低于检出限的结果报告为“未检出”。
本制品适用于专业实验室人员使用,依据标准规范操作。
Principle: The sample is extracted in a water bath at 40℃ for a certain period of time. After the extraction solution is colored with acetylb-ketone, the absorbance of formaldehyde in the colored solution is measured at a wavelength of 412nm using a spectrophotometer. By referring to the standard formaldehyde working curve, the content of free formaldehyde in the sample is calculated.
This section applies to any form of textiles.
This section applies to textiles with free formaldehyde content ranging from 20mg/kg to 3500mg/kg. The detection limit is 20mg/kg. Results below the detection limit are reported as "Not detected".
This product is suitable for use by professional laboratory personnel and should be operated in accordance with standard norms
