Introduction to Atomic Absorption Spectroscopy course
对免费电子学习的压倒性反应HPLCand GC courses has encouraged me to move ahead with the free AAS course which was announced earlier. I understand that everyone has busy work schedules and today’s hectic life style leaves you little or no time to refer to voluminous books to learn any technique. However, for sustained growth learning has to be adopted as a lifelong habit….
Module 1 : Scope of Spectroscopic Analysis
光谱分析基于原子或化合物与特定波长的电磁辐射的相互作用。光谱法提供了基于所选技术和电磁光谱波长的化合物，数量和结构的化学身份的信息。任何实验室中常用的光谱技术是UV –VIS光谱，FT - IR光谱，原子吸收光谱和ICP/ ICP - MS光谱法…。
模块2：原子吸收光谱的演变
关于材料组成的痕量金属研究一直是分析化学的最古老的分支。传统的重量法仍然构成了大多数本科教育实验室的骨干，但是由于速度和精确度的优势，工具方法正在迅速替换它们。
模块3：AAS组件零件的简介
Atomic absorption occurs when a ground state atom absorbs light of a specific wavelength.The amount of light absorbed is governed by Beer Lambert’s law and will increase as the number of atoms of the element in the light path increases. The component parts of Atomic Absorption Spectrometer are similar to a UV -Vis spectrophotometer as both operate on same principle….
模块4：AAS中的光源类型
光源通常来自两种类型。您会熟悉“连续光源”，例如太阳或灯泡，在波长范围内发射电磁辐射的灯泡在可见区域的大约250至700 nm范围内，我们认为这是正常的白光。白光由几种构成彩虹的颜色的波长组成。
模块5：火焰原子吸收光谱
Sample atomisation produces ground state atoms that are necessary for atomic absorption to take place. This involves application of thermal energy to break the bonds that hold the atoms together.
The complete atomisation assembly comprises of:
- Nebuliser
- Spray chamber
- Burner Head….
模块6：石墨炉原子吸收光谱
火焰原子吸收光谱是一种完善且精确的元素分析方法，从而浓度为mg/l（ppm）水平。但是，使用石墨炉的电热雾化可以实现更好的灵敏度。
Limitations of flame AAS
- Burner – nebuliser is a rather inefficient sampling device. Majority of the sample gets drained and the small fraction reaching the flame has a short residence in the light path
- 3-5ml/min的订单的高样本消耗量
- Matrix interferences limit applications particularly in analysis of biological and geological samples…..
模块7：原子吸收光谱中光的分散和分辨率
单色
单色仪是一种设备，该设备可隔离并从较大的入口狭缝处可用的波长传输波长。光的分散可以通过棱镜或衍射光栅获得。使用一对凹面镜和平面光栅的切尔尼·特纳单色仪最广泛地用于原子吸收光谱中…..
Module 8 : Interferences in Atomic Absorption Spectroscopy
Interference is a phenomena that leads to changes in intensity of the analyte signal in spectroscopy. Interferences in atomic absorption spectroscopy fall into two basic categories, namely, non-spectral and spectral.
Non-spectral interferences affect the formation of analyte items and spectral interferences result in higher light absorption due to presence of absorbing species other than the analyte element….
模块9：原子吸收光谱的背景校正
Before you move to background correction it is necessary to understand what is background absorption. The main reason for background absorption is presence of undissociated molecules of matrix that have broadband absorption spectra and tiny solid particles in the flame which may scatter light over a wide wavelength region. When this type of non-specific adsorption overlaps the atomic absorption wavelength of the analyte the ground state absorption is cut…..
Module 10 : 10 Interview questions in Atomic Absorption Spectroscopy
在这个模块中，我在您面前提出了一些典型的问题，当您申请涉及使用原子吸收光谱仪的工作时，您可能会遇到这些问题。我故意没有为您提供量身定制的答案，目的是激励您寻找答案。我敢肯定，如果您查看有关该主题的较早模块，您会找到所有答案。此练习将鼓励您搜索不仅在原子吸收光谱中，而且在活动的其他领域中面临的解决方案……
我在哪里可以参加吗the certificate programs?
谢谢。
HW我可以在AAS，HPLC等上接受完整的培训计划吗？
嗨，亚当斯（Adams），目前在印度新德里的实验室提供了全面的培训。我们可以为您组织一门定制课程，以涵盖您的兴趣应用程序，欢迎您随时下车。我们很快也将启动全面的在线课程，因此请保持联系。
Hi. I'm also intersted in aas, hplc and GC e-courses. Thanks.
Hi Vicki we will keep you posted on all the new lab training courses we will offer.
Hi,
我在尼日利亚，我想参加您的证书课程。请向我解释如何实现这一目标。
Hi,
I have received 7 modules of HPLC e-course so far. Been a long time since I last received a module. Need the last three modules so that I would be done with HPLC course. Kindly do the needful.
And will I start getting the modules of any other course once I am done with HPLC course?
谢谢
安贾纳
嘿，
Olen kiinostanut AAS kursista. Voitteko lähettä mulle tietoa kurssista: aikasta, hinnosta, kurssin sisältöstä.
