The standard substances are very precious materials and are used often to calibrate analytical instruments as those used in high performance liquid chromatography (HPLC by its acronym in English) or gas chromatography (GC its acronym in English). Reducing the amount used of these materials will help directly to reduce costs significantly. But at the same time, the sample size must exceed the minimum weight limit set (this is a typical challenge the R & D and quality control).

The XP56 microbalance by METTLER-TOLEDO solves this challenge with its specification without precedent. 52 g capacity and 1 g resolution. With revolutionary innovations and unique "ErgoClip Flask" and "MinWeigh Door," now can be dosed directly samples tare containers larger, for example, volumetric flasks.

Nanotechnology has created unimaginable impact on the field for the macroscopic world. One of the most striking is the quantum confinement: elementary particles such as electrons, are trapped in closed nano-structures, a phenomenon that generates the art optical and electronic properties with no equivalent in nature and potential technological applications. Until now, scientists had observed confinement isolated objects or irregular systems.

An investigation published in the latest issue of Science and with the participation of researchers of the Higher Council for Scientific Research (CSIC) Jorge Lobo Checa, has detected for the first time the formation of a regular series of electronic confinement (also called quantum dots ) on a copper surface. The finding could be useful in future applications for sensors and computer.

Locate the manufacture of such sensors in Leganés is a natural evolution in the development of Wagner Solar in Spain. After nearly five years of life, which have been ranked among the leading suppliers of thermal and photovoltaic systems, now is the time to participate in the production chain.

The factory will produce large-format sensors LBM to meet European demand

Madrid, November 18, 2008 .- Wagner Solar, technological benchmark in the renewable energy sector, has opened its new factory this morning, large format collector LBM in Leganés. This action is part of the company's corporate strategy to provide the best service to all customers.
