珀金·埃尔默公司开发出320型激光取样器,能对几乎任何固体材料直接取样,以测定它的元素含量,从而避免了制样麻烦。高功率脉冲激光使固体材料的一部分汽化(即烧蚀),然后,通过氩气流把汽化样品直
PerkinElmer has developed the Model 320 laser sampler to sample virtually any solid material to determine its elemental content, thereby eliminating sample preparation troubles. High power pulsed laser vaporized (ie, ablated) a portion of the solid material and then vaporized the sample straight
