甲磺酸培氟沙星介绍：

Reference Material

This certificate is designed in accordance with ISO 17034 and ISO Guide 31. This reference material (RM) was designed,produced and verified in accordance with ISO/IEC 17025, ISO 17034 and a registered quality management system ISO9001.

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.

国家标准《食品安全国家标准动物性食品中氟喹诺酮类药物残留量的测定液相色谱-串联质谱法》

标准名称及标准号

GB 31658.5-2021；用于动物性食品中氟喹诺酮类药物（包括甲磺酸培氟沙星）残留的检测。

适用范围

适用于猪、牛、羊等动物肌肉、肝脏、肾脏及牛奶中甲磺酸培氟沙星等氟喹诺酮类药物的残留测定。

核心检测方法

液相色谱-串联质谱法（LC-MS/MS）：通过色谱分离与质谱特异性检测，实现目标物的定性与定量分析。

检出限与定量限

检出限（LOD）为0.5 μg/kg，定量限（LOQ）为2.0 μg/kg（以甲磺酸培氟沙星计）。

质控样品要求

需使用空白样品加标进行回收率验证，添加浓度范围覆盖LOQ至最高残留限量（MRL）的2倍；回收率应控制在70%-120%，RSD≤15%。

关键实验步骤

1. 样品前处理：匀浆后乙腈提取，C18固相萃取柱净化；
2. 色谱条件：C18色谱柱，梯度洗脱，流动相为甲醇-0.1%甲酸水溶液；
3. 质谱参数：ESI正离子模式，多反应监测（MRM）。

特别说明

甲磺酸培氟沙星与其他氟喹诺酮类药物可能存在交叉干扰，需通过保留时间和特征离子对比例进行确认；检测结果需符合《动物性食品中兽药最高残留限量》要求。
