电感耦合等离子体 (ICP)

电感耦合等离子体或 ICP,亦称为 ICP-AES(原子发射光谱分析)或 ICP-OES(光电发射光谱分析)用于同时分析许多元素。它广泛用于各种市场中,其中包括食品饮料、金属、医药、地质、水及水泥。电感耦合等离子体 (ICP) 使用氩等离子体,然后将雾化的液体样品注入其中。 样品在等离子体中发生离子化,离子以不同的特征波长发光,然后进行测量。氩气需要具有较低的含氧量及含水量,因为这些组分会对某些金属的信号产生屏蔽作用,从而导致错误的偏低读数。 同时还需要具有较低的含烃量,因为烃会造成光谱镜出现碳沉积,从而降低信号强度 氮气在 ICP 中有时也用作冷却气体。

空气产品公司的哪类气体在 ICP 中使用

低含量的总烃(THC)杂质

BIP®氩气和高纯氩气是ICP质谱仪的理想选择。

较低水平的氧和水杂质

BIP®氩气系列,特别适用于 ICP-MS。

BIP®技术具有内置颗粒物过滤器

0.5微米颗粒过滤器消除了气体中含有的金属颗粒干扰。

液态氩气-快易冷®

小储罐解决方案,无需气瓶装卸和更换。 与钢瓶相比,占地面积更小。

CryoEase® Microbulk Solutions

CryoEase® microbulk technology is a modern concept where your gas is supplied by filling on-site vs. the traditional method for smaller volume usage, where gas is supplied by swapping full for empty cylinders and dewars. CryoEase® microbulk supply features specially designed trucks with integrated controls and flexible storage tank options. End usage can be provided as pure gases, cryogenic liquids or gaseous mixtures via a blender installed at your site.
