1. Ch. 1. INTRODUCTION Geochemical Analysis?
Chemical analysis of the materials in a planetary system (solids + liquids + gases in an Earthlike planet)
Analytical chemistry (principles and methodology of analysis) for those materials  Analytical Geochemistry
Why is it in the curricula of geology?
Complexity of materials
Unique environments of the system

2. Ch. 1. INTRODUCTION Past, Present, & Future
Has been developed parallel to the analytical chemistry
Started w/ data collection (e.g. F.W. Clarke’s ‘The Data of Geochemistry’ in 1922)
Application of data for the interpretation of Earth history and processes
The most advanced technique has been practically utilized in the geochemical analyses
Varieties of instruments of new technology is now being used in this field
What‘s coming for the future?

3. Ch. 1. INTRODUCTION Questions for everyone (will be discussed)
What is the typical analytical method used in your study field? What is the analytical instrument for that method?
When does the instrument appear first time, and has any improvement of it’s performance been made?
Can you think of any possible advance in the instrumentation (of that instrument)? What’s the reasoning?
Is there any emerging (new) methods of analysis on your field, although it hasn’t been fully accepted (or approved) yet?
If you think the new method is interesting, why is it so?
Is there any analytical instrument you’d like to develop? What are the reasons?
