give them important clues about the current chemical environment of the moon (from surface samples) and about the presence of a lunar sea or ocean in the distant past (from core samples). Present-day commercial NMR spectrometers are capable of accomplishing, unaided, the work assigned to the JPL team with a creditable degree of success. But when you're analyzing samples that cost about a millio...
متن کاملReview of analytical instruments for EEG analysis
Since it was first used in 1926, EEG has been one of the most useful instruments of neuroscience. In order to start using EEG data we need not only EEG apparatus, but also some analytical tools and skills to understand what our data mean. This article describes several classical analytical tools and also new one which appeared only several years ago. We hope it will be useful for those research...
متن کاملSmall-Scale, Low-Cost Analytical Instruments: Extended Opportunities for Learning Analytical Chemistry
This contribution challenges the often misleading perception that there is only one way of doing analytical chemistry, i.e., with complicated and costly professional instrumentation. And if a school or university does not possess such instrumentation, or has no access to it, there is no other way to proceed. Here we describe a low-cost spectrometer with a microreaction chamber and a tri-colour ...

available, and many other factors. The list in Table 3 is by no means exhaustive and has been designed to facilitate the decision as to whether a given instrument is practicable under the conditions prevailing in the laboratory concerned. These criteria cannot be assessed as objectively as those given previously. Conclusions Consideration of the above criteria should make it possible to arrive ...
متن کاملIntegrating laboratory robots with analytical instruments--must it really be so difficult?
Creating a reliable system from discrete laboratory instruments is often a task fraught with difficulties. While many modern analytical instruments are marvels of detection and data handling, attempts to create automated analytical systems incorporating such instruments are often frustrated by their human-oriented control structures and their egocentricity. The laboratory robot, while fully sus...
