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 external 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.

标准名称及标准号

GB/T 5750.8-2023《生活饮用水标准检验方法第8部分：有机物指标》

适用范围

适用于生活饮用水及其水源中苯甲醚等有机物的检测，涵盖水样采集、前处理及仪器分析流程。

核心检测方法

采用气相色谱-质谱联用法（GC-MS）。水样经液液萃取富集后，通过色谱柱分离，质谱检测器定性定量分析。

检出限与定量限

检出限为0.01 mg/L，定量限为0.04 mg/L。需通过空白样品校准验证方法灵敏度。

质控样品要求

每批次样品需包括空白样、平行样及加标回收样。加标回收率应控制在80%-120%，平行样相对偏差≤20%。

关键实验步骤

1. 水样用二氯甲烷萃取，浓缩至1 mL；
2. 色谱条件：DB-5MS毛细管柱（30 m×0.25 mm×0.25 μm），进样口温度250℃，质谱扫描范围50-450 m/z；
3. 数据采用内标法定量，目标物响应值与内标物（如氘代甲苯）比值计算浓度。

特别说明

1. 苯甲醚易挥发，萃取过程需避光低温操作；
2. 实验废弃物按危化品处理；
3. 检测结果需结合空白样扣除背景干扰。
