10:00-11:00 Basic Knowledge for Using SEM

Kazuteru Kawauchi
Since scanning electron microscope (SEM) was first commercialized about 50 years ago, SEM
has achieved remarkable progress. As is well known, SEM can observe surface morphology andcompositional contrast, and various types of SEMs have been developed. However, theirperformance and functionality are greatly different from each other. To utilize these different
SEMs, it is essential to recognize their features as well as to correctly understand the contrast
information of SEM image. The aim of this lecture is to help SEM users to understand the basicsof SEM, including the instrument principals, specimen preparation and elemental analysis.

11:00-12:00 Introduction to EPMA

Rie WakimotoThe Electron Probe Micro Analyzer (EPMA) is an effective instrument for surface observation,
elemental analysis and measuring the elemental distribution of a variety of materials, including
metals, minerals, and others by irradiating electron beams onto the substance surface. EPMA
today is playing an active role worldwide, as an all-purpose, multi-functional tool equipped withelectron optics technology, X-ray spectrometry technology, system control and data processing
technology. EPMA has evolved into an instrument that can handle elemental analysis of submicron areas as well as observation, analysis, and image analysis for large areas.This session isa lecture about the basic principle of EPMA, especially WDS (Wavelength Dispersive X-raySpectrometer). In addition, some applied analyses examples are introduced.

13:15-14:45 Introduction to Mass Spectrometry Jun Tamura
Mass spectrometry (MS) has extremely wide applications – from the elemental and isotopic
analysis of extraterrestrial materials to the comprehensive analysis of proteins in human body.
MS is also quite different from any other spectrometry/spectroscopy – they rely on theexcitation by and absorption/emission of electro-magnetic radiation (radio wave,infrared/visible/ultraviolet light, X-ray, and gamma ray) whereas MS directly deals with theatoms and molecules. This makes MS an extremely powerful analytical technique but alsodifficult for the beginners to get into – many of the concepts and terms used are unique to MS
and there is no analogy in other analytical techniques.
This lecture covers basics of MS, including the principle, instrumentation, and the concepts andterms unique to MS. Some popular applications of organic MS are also discussed.
15:00-16:30 Get the most out of your NMR instrument.

Practical Tips

What is shimming? What is lock signal? Why I need tuning? How I can optimize experimental
time? Answer to these questions is not a requirement for operating a NMR instrument. NMR
spectrometers can operate in a highly automated mode reducing input from a user to aminimum. Nevertheless, knowledge of how a spectrometer works gives the user a better
control of the instrument and allows him to operate it in a more efficient and productive way.
In this short lecture, I will explain the preparatory NMR procedures prior to execution of a NMR
experiment and the main acquisition parameters that define a NMR experiment.

You can enter or exit any time during this seminar. Please register in advance.
