COSMOSIL烷基柱 04599-41 COSMOSIL烷基柱还包括C22 （二十二烷基），C8（辛烷基），C4（丁基）和TMS（三甲基）等烷基键合固定相的烷基柱。根据各种填料的疏水性大小不同，保留时间依次为C22=C18C8C4TMS。这些柱子的疏水性比C18柱或C22更低，能将高疏水性化合物和疏水性差别很大的化合物有效分离。C22的疏水性与C18大致相同。但是，C22的立体选择性高于C18柱，所以C22有更好的分离效果。The COSMOSIL苯乙基色谱柱和 and the COSMOSIL 氰基色谱柱提供另一种基于π-π 相互作用分离的选择。建议使用这些色谱柱当烷基固定相色谱柱不能很好分离类似化合物的时候. 订货信息：● 分析/ 制备色谱柱 (粒径: 5 μm)COSMOSIL 5C22-AR-II 色谱柱色谱柱尺寸 内径 x 长度 (mm)货号4.6× 5005848-414.6×10005849-314.6×15004598-514.6×25004599-416.0×15005850-916.0×25005851-8110×25004969-9120×25005183-41COSMOSIL 5C22-AR-II 保护柱 色谱柱尺寸 内径 x 长度 (mm)货号4.6×1004881-2110×2005554-81COSMOSIL 5C8-MS 色谱柱色谱柱尺寸 内径 x 长度 (mm)货号4.6× 5038153-114.6×10038154-014.6×15038155-914.6×25038156-816.0×15038157-716.0×25038158-6110×25038159-5120×25038160-11COSMOSIL 5C8-MS 保护柱色谱柱尺寸 内径 x 长度 (mm)货号4.6×1038151-3110×2038152-21COSMOSIL 5C4-MS 色谱柱色谱柱尺寸 内径 x 长度 (mm)货号4.6× 5038163-814.6×10038164-714.6×15038165-614.6×25038166-516.0×15038167-416.0×25038168-3110×25038169-2120×25038170-81COSMOSIL 5C4-MS 保护柱色谱柱尺寸 内径 x 长度 (mm)货号4.6×1038161-0110×2038162-91COSMOSIL 5TMS-MS 色谱柱色谱柱尺寸 内径 x 长度 (mm)货号4.6× 5038173-514.6×10038174-414.6×15038175-314.6×25038176-216.0×15038177-116.0×25038178-0110×25038179-9120×25038180-51COSMOSIL 5TMS-MS 保护柱色谱柱尺寸 内径 x 长度 (mm)货号4.6×1038171-7110×2038172-61COSMOSIL 5PE-MS 色谱柱色谱柱尺寸 内径 x 长度 (mm)货号4.6× 5038183-214.6×10038184-114.6×15038185-014.6×25038186-916.0×15038187-816.0×25038188-7110×25038189-6120×25038190-21COSMOSIL 5PE-MS 保护柱色谱柱尺寸 内径 x 长度 (mm)货号4.6×1038181-4110×2038182-31

优质进口LuAG:Ce晶体或Ce:LuAG晶体或铝酸镥石榴石为闪烁体，可根据用户要求做成薄片的荧光屏，典型的直径范围为2mm到50mm,厚度范围为0.1mm到5mm.当然我们也可以提供其他各种形状和大小的探测器，包括：棱镜型/球形或薄片型，并提供当面抛光，双面抛光和多面抛光。并提供铝、鋯或氧化铟锡的窗口等多种选择。LuAG:Ce, Lutetium Aluminum Garnet activated by cerium (chemical formula Lu3Al5O12), is a relatively dense and fast scintillation material. Its density of 6.73 g/cm3 is about 94% of the density of BGO (7.13 g/cm3). Its decay time is much faster (70 ns) than that of BGO (300 ns). This is of advantage in time dependent and coincidence measurements. The wavelength of scintillation emission is about 535 nm, which is ideal for photodiode and avalanche diode readout. The material can also be used for imaging screens, similarly to YAG:Ce. A particular advantage of LuAG:Ce is its higher density resulting in thinner screens with higher spatial resolution. The material is mechanically and chemically stable, and can be machined into a variety of shapes and sizes including prisms, spheres and very thin plates.LuAG:Ce晶体或Ce:LuAG晶体或铝酸镥石榴石可用于电子、X射线、伽玛射线、UV和EUV的探测，具有如下典型应用：荧光屏或成像屏 我们提供的闪烁屏或成像屏是由YAG:Ce, LuAG:Ce和YAP:Ce晶体材料构成。目前提供如下三种选择： *标准的成像屏：直径可达50mm,厚度0.5-0.1mm.用于：X射线、电子、UV和EUV的成像。 *带衬底超薄屏：超薄LuAG:Ce晶体或Ce:LuAG晶体或铝酸镥石榴石厚度可小到为0.005mm，耦合到光纤光学、玻璃、石英等衬底上使用。可用的规格是：厚度为0.010mm直径最大为40mm, 厚度为0.005mm直径最大为25mm. *独立薄成像屏: 这种超薄LuAG:Ce晶体或Ce:LuAG晶体成像屏是独立使用的闪烁屏，不需要耦合到衬底上。目前可用的规格如下： LuAG:Ce晶体或Ce:LuAG晶体或铝酸镥石榴石成像屏：厚度0.050mm的屏直径最大是50mm,厚度为0.025mm的闪烁屏的最大资金是10mm LuAG:Ce晶体或Ce:LuAG晶体或铝酸镥石榴石成像屏：厚度0.1mm的屏直径最大是50mm, 厚度为0.050mm的屏的最大直径是10mm. 这种独立使用的闪烁屏非常脆，极易损坏，为此，我们为您提供了一种刚玉外壳用于保护成像屏，或者可提供陶瓷或钢铁外壳保护。 导光元件 我们为各种探测器提供不同的导光元件，根据不同的闪烁材料和应用，我们提供如下多种材料的导光元件： 有机玻璃（PMMA),近紫外的特殊有机玻璃，光学玻璃BK7, 石英玻璃，有机玻璃或石英玻璃光纤，蓝宝石，YAG 电镜探测器 我们提供独具特色的电镜探测器采用YAG:Ce,YAP:Ce,CRY18材料制成，特别适合电子探测和成像，并配备多样的导光元件，非常方便测量。 闪烁探测器：提供多种类型的探测器用于电镜，这些探测器具有工作寿命长，荧光效率好等特点，提供的标准产品有： 标准探测器：SE, BSE,TEM,Dark Field (ADF) 特殊探测器：带镜头的探测器，阵列探测器，阴极荧光探测器（CL)
