产品详情

西安思莫徳科技有限公司生产的纳米孔单分子检测仪器(SIMOLDE NanoF1)是国内首台成熟的单分子专用检测设备,具有集成便携、高性能、可定制、噪音低等核心优势。自主研发了独有的专用集成电路,实现了全信号链的重新设计。

集成便携:检测设备体积小(SIMOLDESMDF1Basic型号产品尺寸约26cm*15cm*9cm,整体占地面积为一本16开书本大小)、抗震和电磁屏蔽性能好,可带到现场,从源头进行样品检测。

信号响应速度快:最高带宽100kHz以上,采样速度最高250kHz。

可定制:根据客户需求,以下参数均可定制:量程范围:±2.5nA至±2.5μA;滤波截止频率:256Hz至100kHz;带宽范围:1kHz至100kHz;施加电压范围:±200mV至±2V。

噪音低:采用标准模块(图b)进行实测,在同样带宽和采样速率下,与elements公司的商业化eONEHS型号仪器对比(图a右),本公司产品(SIMOLDESMDF1Basic型号)的噪音更低
