trace sensitivity

The studied immunosensor exhibited high sensitivity and could be used to screen detection of trace HCG in the saliva. 2.

该免疫传感器灵敏度高，可用于唾液中痕量HCG的快速筛测。

But it cannot determine directly trace element in the cleaning water for not enough sensitivity.

但因其灵敏度不够无法直接测定清洁水中痕量元素.

This method is suitable for determining trace acrylamide in fried rice product with rapidity, sensitivity and accuracy.

该法快速、灵敏、准确，适合油炸米制品中痕量丙烯酰胺的测定。

The ionization interference and coexisting element interference have been eliminated by the potassium sodium mix ionization suppressor and the lanthanum diluent. The sensitivity of this method is higher. It can be direct determined that the trace strontium in mineral water.

使用钾、钠混合消电离剂和镧释放剂，消除电离干扰和共存元素干扰，本法灵敏度高，可直接测定矿泉水中微量锶。
