上海泉岛公司是经营色谱配件和消耗品为主的专营公司。公司于1999年成立，多年来，凭着优质的产品，良好的信誉，完善的服务，受到了广大色谱工作者的充分肯定与信任。

　　我公司现已是众多优秀品牌的代理：瓦里安色谱消耗品一级代理(CP-SIL系列毛细管柱,VF系列GC/MS柱;Bond Elut系列固相萃取柱等)；日本COSMOSIL系列HPLC柱总代理（NACALAI公司生产）；德国DR.公司和美国CHEMSERVICE化学标准品(农药,兽药,环境,食品安全等)代理。

　　真诚而专业的服务是本公司的宗旨，我们认为，随着色谱使用范围的不断扩大，色谱工作者对服务的要求也越来越高，而这正是本公司的优势（我公司销售员均为相关专业大学毕业，对色谱较为熟悉、专业），并且我们将继续不断的加以提高、完善。
