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.

GBZ/T 300.62-2017
工作场所空气有毒物质测定第62部分：丁酮、戊酮和甲基异丁基甲酮

适用范围

适用于工作场所空气中3-戊酮的溶剂解吸-气相色谱检测，涵盖采样、前处理及仪器分析全流程，用于职业卫生环境监测。

核心检测方法

采用活性炭管采集空气中3-戊酮，经二硫化碳溶剂解吸后，使用气相色谱仪（FID检测器）分离定量，内标法定量分析。

检出限与定量限

检出限（LOD）为0.2 μg/mL，定量限（LOQ）为0.6 μg/mL，采样体积按3L计时最低检测浓度为0.07 mg/m³。

质控样品要求

每批次样品需包含空白对照、加标回收样（加标量为待测物浓度的50%-150%）和实验室平行样，回收率应控制在85%-110%。

关键实验步骤

1. 采样：活性炭管以0.5 L/min流速采集15 min空气样品；
2. 解吸：加入1 mL二硫化碳，超声解吸30 min；
3. 分析：气相色谱仪进样1 μL，DB-1色谱柱（30 m×0.32 mm×1.0 μm），柱温程序升温（初始50℃，10℃/min升至150℃）。

特别说明

1. 二硫化碳需经纯化处理以降低背景干扰；
2. 避免与其他酮类化合物（如丁酮）保留时间重叠，必要时调整色谱条件；
3. 活性炭管解吸效率应≥90%，否则需重新校准。
