商业产品测试实验室样本管理的要素

有效的样本管理在提高商业测试实验室的生产率和利润中起着重要作用。一篇标题为较早的文章Sample Management – key to success of laboratory operationscovered some useful guidelines that should be adopted during different stages of testing from receipt till disposal of samples post-analysis.

本文建议一组程序应遵循，以实施前面文章中推荐的准则。

样本管理涵盖了一系列涉及的序列：

• 样品收据
• Sample booking and coding
• Sample distribution for analysis
• 在实验室中进行样品处理
• 采样机密性

Sample Receipt

Samples for testing are received in the laboratory through several modes such as collection from customer site by laboratory employee, personal delivery by customer representative or through courier delivery. On receipt the laboratory receptionist ascertains the following before accepting the sample and assigning it a tracking number and other details:

• 样本附有一封客户信件，提供示例详细信息，分析要求和日期需要分析
• 样品容器未损坏或泄漏
• 标签已正确固定并且完全清晰
• 样本在其到期期内
• 标签上清楚地提到了样本存储和处理说明

Sample Booking and Coding

在满足分析条件以及随附的请求和示例详细信息之后，接待员进入了样本记录，并将跟踪号分配给样本，然后再将其交给客户支持小组。

如果信息不完整或对容器标签的损坏，则将样品保留并告知客户。如果一周后未收到可腐烂样本的响应，则从宣传之日起一个月后，不可腐烂的样本。

The customer service group is responsible for:

• 生成具有唯一产品标识（报告编号）的产品主的生成，并在容器上贴上带有样品ID的条形码贴纸
• 如果没有主人，则根据分析要求创建它
• Sample is handed over to quality assurance division for preview of testing requirements such as method reference, code, batch number, manufacturing date, expiry date, sample quantity, test parameters, claims, limits, etc.

分析样本分布

在预订，对质量保证部门进行的编码和验证后，样本将传递给有关实验室的部门。该部分负责人在实验室信息管理系统或同等软件（如果有）中提供相关条目，或者在交给有关分析师之前先维护软拷贝和硬拷贝详细信息。在分配给化学家之前，分段头确保：

• 样本被细分并移交给有关的相关化学家采取预防措施以防止交叉污染
• Prior to analysis samples are stored in specified conditions such as temperature and humidity.

Sample Handling in Laboratories

如上所述，样品保持在指定条件下，并在每个阶段进行护理以防止其他样品或采样工具的测试样品交叉污染

• Do not return excess of sample after weighing to the original sample container
• Always make use of clean spatulas for taking sample aliquots
• Enter results in analysis records and simultaneously in laboratory information management software, if available
• Seal any unused sample on completion of analysis and hand over to Stores officer for disposal or return to customer

处置或返回可返回的样品

分析后的样本不仅仅放入废物箱中，而是交给商店官员进行所需的行动。

Stores Officer arranges to return the returnable samples if agreed with customer or else disposes of samples following the suggested guidelines :

• 采样类型所需的动作
• 易腐物即时处置
• 毒品和化妆品1年存储
• 参考实验室的样本3个月
• 出口检查机构的样本三个三个月
• 采样机密性

Laboratory ethics demands that sample confidentially be maintained throughout the stages from sample receipt till reporting of results to avoid any biases or customer pressures.

• 样本编码有助于从分析师或其他样品处理程序中隐藏样本身份
• Analyst should not disclose analysis results direct to customer or to laboratory colleagues
• 分析师所需的任何技术查询或信息应仅通过客户服务组传达给客户

遵守上述建议将有助于简化您的实验室操作并促进与客户的合理业务关系。
