Carbon Rods

Grade 1 Spec-Pure Carbon Rods

Spectroscopically pure graphite structure carbon rods with an impurity level of 2ppm or less with 1ppm as maximum level for each element. The rods are all 12" long with three nominal diameters （1/8", 3/16" and 1/4"） to comply with the carbon source used in different high vacuum carbon evaporators. Highly recommended for TEM, FESEM, FIB, WDS, EBSD, Microprobe and more critical SEM/EDS applications.

光谱纯石墨结构碳棒，杂质含量等于或小于2ppm，每种元素的含量为1ppm。 这些棒全长12英寸长，具有三种公称直径（1/8“，3/16”和1/4“），以符合不同高真空碳蒸发器中使用的碳源。 推荐用于TEM，FESEM，FIB，WDS，EBSD，微探针和更关键的SEM / EDS应用。

Grade 2 Carbon Rods, Technical Grade

Technical grade graphite structure carbon rods contain impurities typically equal to or less than 50ppm. However, as an exception some batches can contain impurities up to 200 ppm. The impurities typically consist of: （ppm max.）: Ca 20, Fe 20, Cr 10, Si 2-5, Ti 8-10, V 4-4 and traces of other elements. Use this grade for non-critical SEM and SEM/EDS applications.

工业级石墨结构碳棒含有通常等于或小于50ppm的杂质。 但是，有些批次可能含有高达200 ppm的杂质。 杂质典型地由以下物质组成：（ppm大值）：Ca 20，Fe 20，Cr 10，Si 2-5，Ti 8-10，V 4-4和痕量的其它元素。 用于非关键的SEM和SEM / EDS应用。
