基本信息
| General description【一般描述】 | HPLC cartridge Purospher® STAR NH2 HPLC columns are amino-bonded high-purity silica columns primarily for carbohydrate analysis. The particular benefits of these columns are the very high separation efficiency and the absence of metallic impurities, giving consistent symmetrical peaks. The connection to the HPLC system is being accomplished by use of the manu-CART NT cartrige holder (1.51486). |
