Uncertainty

The certified value(s) and uncertainty(ies) are determined in accordance with ISO 17034 with an 95% confidence level (k=2). Uncertainty is based on the Total Combined Uncertainty, including uncertainties of characterisation, homogeneity and stability testing. Stability values are based on real evidence opposed to simulation.

The producer certifies that this reference material meets the specification stated in this certificate until the expiry date, provided it is stored unopened at the recommended temperature herein. Product warranties for this reference material are set out in the terms and conditions of purchase.

Intended Use

This RM is intended for use in a laboratory as a calibration and quality control standard or in method development for analytical techniques.

Safety

Proper precautions should be observed while handling. See Safety Data Sheet.

Traceability

The balances used for gravimetric measurements are calibrated with weights traceable to the national standards (DKD). The calibration of the balances is verified daily internally and annually by an external7 accredited calibration service. Chromatographic methods are traceable to the International System of Units (SI).

Homogeneity

Random replicate samples of the final packaged RM have been analysed to prove homogeneity compliant with ISO 17034.

Storage

The RM should be stored in the original sealed container at the indicated temperature.

Instructions for use

It is recommended to use 1 mg as the minimum sample size and if less material is used, to increase the certified uncertainty by a factor of two for half sample and four for a quarter of sample. If storage after opening is necessary, the RM should be tightly closed and kept from light and moisture. If the RM was in a sealed ampoule, it should be transferred to a vial with minimum head space.

《生活饮用水标准检验方法 第9部分:农药指标》
标准名称及标准号 GB/T 5750.9-2023《生活饮用水标准检验方法 第9部分:农药指标》
适用范围 适用于生活饮用水及其水源水中灭菌磷(CAS:5131-24-8)等有机磷农药的检测。
核心检测方法 采用气相色谱-质谱联用法(GC-MS),通过固相萃取(SPE)前处理技术进行样品富集与净化。
检出限与定量限 检出限(LOD)为0.02 μg/L,定量限(LOQ)为0.05 μg/L。
质控样品要求 每批次样品需包含空白对照、加标回收样品和平行样;加标回收率应控制在70%-120%。
关键实验步骤 1. 样品萃取:使用C18固相萃取柱富集目标物;
2. 仪器分析:采用DB-5MS色谱柱(30 m×0.25 mm×0.25 μm),梯度升温程序分离目标物;
3. 质谱检测:选择离子监测(SIM)模式定量。
特别说明 灭菌磷易受光解影响,实验过程中需避光操作;样品保存需添加1%抗坏血酸以防止氧化。
