Reliable products with a long history from MACHEREY-NAGEL.
NUCLEODUR is a newly developed ultra-high purity silica gel that serves as a perfect spherical packing material with excellent mechanical strength and particle size distribution, and it is an ultra-high purity silica gel with an extremely low content of metal impurities. By using a specially modified silica gel with very few metal impurities, the "NUCLEODUR C18 GRAVITY column," which has a high density of ODS bonded, demonstrates high chemical stability and can utilize mobile phases with a pH range of 1-11. This feature is effective for method development, particularly when it is necessary to improve the separation of basic samples using mobile phases with high pH that cannot be used with standard columns. 【Features】 ■ Perfect spherical packing material with excellent mechanical strength and particle size distribution ■ Ultra-high purity silica gel (Al, Fe, Na < 5ppm, Ca < 10ppm, Ti, Zr < 1ppm, As < 0.5ppm, Hg < 0.05ppm.) ■ Uniform packing material surface structure ■ High chemical stability (usable at pH 1-11), etc. *For more details, please refer to the catalog or feel free to contact us.
