适用领域

    高分子材料、精细化工、生物化学、药物化学等有机化合物和部分无机化合物的结构分析

面向学科

    应用于化学、生物、材料及食品学科等不同研究领域

样品要求

    1)薄膜样品:直径小于12 mm,高度小于3 mm,要求样品上下表面平整,高低起伏小于1μm,如尺寸超过范围需收取相应加工费     2) 液体样品:请配好胶体溶液,保证样品均匀分散,要求无沉积,溶液澄清透明。样品如需超声或稀释请事先说明,稀释请提供相应的溶剂(去离子水除外),并说明稀释倍数。液体样品一般涂到新鲜解离的云母片上,如样品在云母片上吸附不好,请客户自行将样品涂到其他底材上(如硅片)进行测样;     3) 固体粉末样品:由于AFM是盲扫,对样品的分散性要求非常高,因此最好是以液体的形式进行测试。固体粉末样品一般只适合溶解性或分散性较好的样品,通常提供不超过30 min的超声预处理,溶剂由客户提供(去离子水除外),并由客户提供详细的制样条件     4)生物样品:蛋白、细胞及DNA等样品,请提供详细的制样过程,由于溶液中含有盐,因此请调好浓度,减少盐对测试结果的影响     5)由于样品分布的不均匀性,请客户提供样品的SEM或TEM图,或者提供参考文献中AFM的效果图,以提高结果的准确性     备注:请客户提供样品的成分信息,如样品具有腐蚀性、传染性等危害,请在寄样前确认能否测量,并提供相应的防护措施

收费标准

    1)形貌 150元/样;     2)形貌+EDS点扫 200元/样;     3)形貌+EDS线扫 200元/样;     4)形貌+mapping 300元/样;     5)单独EDS点扫 150元/样;     6)单独EDS线扫 150元/样;     7)单独EDS面扫 200元/样;
