The purpose of the lower detection limit of LIBS is implemented. 成功实现了降低LIBS的检测极限的目的。
In addition, lower detection limit were obtained in the determination of residual benzene homologues with high boiling points. 该法的精密度比顶空法好,对于测定较高沸点的残留苯系物,检出限也更低。
This method has no system error, with accurate result low lower detection limit, and excellent analytical accuracy, It can satisfy the rapid analysis of trace As, Sn, Al and acid soluble Al in steel during melting. 本方法无系统误差,结果准确,检出下限低,分析精密度良好。可满足冶炼过程中对微量砷锡铝和酸溶铝的快速分析。
Compared to sensors based on Ni / Al-LDH and NiO, glucose sensor based on metallic nickel nanoparticles exhibits faster response speed, lower detection limit and higher sensitivity. 与基于镍铝水滑石、氧化镍的葡萄糖传感器相比,基于金属镍纳米材料的葡萄糖传感器显示出了更快的响应速度、更低的探测极限和更高的灵敏度。
The sensitivity of this method was improved more than 9 times compared with ordinary flame atomic adsorption spectrometry, and the lower detection limit can reach to 0.02 μ g / mL. 对铅的测量灵敏度较常规火焰原子吸收法提高了9倍以上,检出限低达002μg/mL。
