在诸如AAS、NIR、ICP以及XRF等等的化学和物理分析方法中，分析样品不仅必须要预先经粉碎达到一定的满足分析要求细度，同时还必须达到尽可能高的均化度。 可靠而且准确的样品分析必须有可重复性的样品前处理进行保障。RETSCH在这一领域为您提供一整套完整的解决 方案，包括各种最现代化的研磨仪和粉碎仪，能够提供满足各种样品特性要求的粗粉碎、细粉碎和超细度粉碎处理。丰富的研磨件（切割头）和配件供应保证了我们 的仪器能够在各种前提下实现满足分析要求的样品前处理，消除粉碎过程中产生样品污染的可能性，同时满足对样品本身进行温和维护的要求。
Genetic engineering opens up new possibilities in areas such as medical research, development of alternative fuels or global food supply. It is used to modify the characteristics of plants in order to increase the crop yield, improve defense against predators, pesticides or draught, but also increase concentrations of essential vitamins. However, with regards to food the use of genetic engineering is a fairly controversial issue.
