實驗室導入EN71-3方法, 遇到前處理的一些問題, 求助大家.實驗用材料為塑料顆粒, 經過粉碎.1) 加入萃取鹽酸溶液, 樣品粉末浮在溶液上, 經過搖擺, 粉末還會黏在溶器內壁上, 這樣會影響萃取量, 怎麼解決? 2) 是否可以加入浸潤劑? 請推薦可用的浸潤劑, 實驗需添加多少量?3) 有沒有標準物質用來做回收率驗証?新接觸這個方法, 請大家分享一些經驗, 謝謝

各位大侠，你们在做EN1811试验时有没有遇到最终测试出来的结果平衡样一个超出标准限制，一个很小？由于最近做了一些EN1811试验，测试出来的结果平衡样一个高一个低，这样很难出结果？不知道各位有没有更好建议给我呢？我应该从哪些方面去注意呢？这样的问题出了好多次，都不知道从哪些方面去着手呢？做质量控制时，结果又很好，但做实验时老是出现这样（上述）的情况？

This has led to many new developments in legislation and monitoring of environmental pollutants.A comprehensive treatment of these current trends is presented in this book. The reader is helped by a sound understanding of modern instrumental methods such as GC/MS, thermal desorption and purge-trap methods, that are available to meet these legal requirements. Many practical applications assist familiarization with these techniques. This work pays particular attention to methods of monitoring different types of chemicals ranging from pesticides to industrial pollutants. The description of the different design aspects of instruments and their effects on analysis aids the development of precise instrumental methods for the various specific problems in quality assurance.

在实验中常常要取50ml的水或者其他的液体，你是用什么取的呢？

我看了一下国标18582和18581，里面对液体涂料的制样过程是先把涂料制作成漆膜。我对比了下EN 71-3 ,第8.9部分“油漆、清漆、生漆和固态或液态状的类似材料”，上面好像没有象国标那样把液态油漆制成漆膜。那该怎么处理呢？是不是直接称液态的油漆然后水浴溶出呢？还有那固态的油漆该怎么处理？

昨天中午打完电话回去后，晚上读幼儿园大班的女儿打视频过来，刚开始以为是母亲打过来的视频（看微信头像），当母亲说是我女儿自己打来的时候，心里惊了一下，年纪这么小，既然记得爸爸的微信头像，能自己打视频给爸爸，很懂事。接通视频后，女儿就直接说“爷爷奶奶外公外婆爸爸妈妈，节日快乐，你们辛苦了，我爱你们”，虽然知道这话是幼儿园老师教小朋友的，但通过女儿说出来，很感动，心里莫名的愧疚，由于我和妻子在外工作，女儿在家读幼儿园由爷爷奶奶照顾着，知道心中的想念和牵挂。女儿接着说“爸爸，今天在幼儿园，老师教大家唱了一首歌（感恩的心），好多小朋友哭了，刚开始是一个小朋友哭，接着另一个小朋友哭（女儿记得哭的小朋友的名字），最后我也哭了。”是啊，一首大人唱的歌，小朋友也懂的它的意义，能产生共鸣，可想对父母的思念是那么深。俗话说的好：为人父，方知父母艰和恩，这需细细体会。父母、爱人：你们辛苦了； 女儿，你很懂事、聪明，爸爸也爱你。

EN71-6需要测试吗？还是去判断？

有兴趣的来，没兴趣的跳过。1058 ANALYTICAL INSTRUMENT QUALIFICATION INTRODUCTION A large variety of laboratory equipment, instruments, and computerized analytical systems, ranging from simple nitrogen evaporators to complex multiple-function technologies (see Instrument Categories), are used in the pharmaceutical industry to acquire data to help ensure that products are suitable for their intended use. An analyst's objective is to consistently obtain reliable and valid data suitable for the intended purpose. Depending on the applications, users validate their procedures, calibrate their instruments, and perform additional instrument checks, such as system suitability tests and analysis of in-process quality control check samples to help ensure that the acquired data are reliable. With the increasing sophistication and automation of analytical instruments, an increasing demand has been placed on users to qualify their instruments.Unlike method validation and system suitability activities, analytical instrument qualification (AIQ) currently has no specific guidance or procedures. Competing opinions exist regarding instrument qualification and validation procedures and the roles and responsibilities of those who perform them. Consequently, various approaches have been used for instrument qualification, approaches that require varying amounts of resources and generate widely differing amounts of documentation. This chapter provides a scientific approach to AIQ and considers AIQ as one of the major components required for generating reliable and consistent data. Note that the amount of rigor applied to the qualification process will depend on the complexity and intended use of the instrumentation. This approach emphasizes AIQ's place in the overall process of obtaining reliable data from analytical instruments.Validation versus Qualification In this chapter, the term validation is used for manufacturing processes, analytical procedures, and software procedures and the term qualification is used for instruments. Thus, the phrase “analytical instrument qualification” (AIQ) is used for the process of ensuring that an instrument is suitable for its intended application.
