The Future

Electrically driven separations on microchips have a number of advantages over conventional CE. The first is the further reduction in reagent consumption, in terms of both sample and buffer solutions. This will reduce the running costs of the system, and also the associated waste disposal costs. Second, as methods to mass-produce the devices become more widespread, the cost will decrease. This will allow totally disposable systems to be used. Finally, perhaps the most important advantage will be the portability of analyser systems, which will be able to be used in remote on-site mode. Without doubt, microtechnol-ogy revolutionized the electronics industry, and it will do the same for much chemical analysis.

There remain two other areas where chips or micro reactors will find important uses, and that is in chemical discovery and manufacturing. Combinatorial chemistry can produce thousands of compounds per day, which places a significant demand on the analysis. The fabrication of multiple analysis channels with high spatial resolution may offer an analytical solution for this problem; however, appropriate detection must also be available. Mass spectrometry interfaced to an electrophoretic separation chip is one possible answer. However, there is no reason why reactions cannot be carried out on such devices. Since it does not require the investment of a large chemical plant, the reactions can be performed where required, thus reducing the need to transport hazardous chemicals across countries. Since many reactors can be constructed on a single chip, and many chips located in the same area, it is evident that this technology will provide hazardous or chemically unstable chemicals where they are required.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
