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.

标准名称及标准号
HJ 784-2016 土壤和沉积物 多环芳烃的测定 高效液相色谱法
适用范围
本标准适用于土壤和沉积物中菲(CAS:85-01-8)及其他15种多环芳烃的定量分析,检测基质包括干重≤40%的土壤及河流、湖泊沉积物。
核心检测方法
样品经索氏提取或加压流体萃取后,通过硅胶柱净化,采用高效液相色谱-荧光检测器/紫外检测器分离分析,以保留时间定性、外标法定量。
检出限与定量限
菲的方法检出限为0.02 mg/kg(干基),定量限为0.08 mg/kg(干基),当取样量为10.0 g时适用。
质控样品要求
每批次样品需包含至少1个实验室空白、1个平行样及1个加标样品,加标回收率应控制在70%-130%,相对偏差≤25%。
关键实验步骤
1. 样品研磨过筛(2 mm筛孔);
2. 加入替代物(如氘代菲)进行提取;
3. 净化后氮吹浓缩至0.5 mL;
4. 色谱条件:C18色谱柱,流动相为乙腈-水梯度洗脱,荧光检测波长λexem=260/340 nm。
特别说明
菲易受光解影响,样品前处理需避光操作。若存在异构体干扰,需优化色谱分离条件或采用质谱确认。
