用于 ICP-MS 的安捷伦高级阀系统 (AVS MS)
高级阀系统 AVS MS
AVS MS 与安捷伦 ICP-MS 系统的 HMI 技术和使用单碰撞池模式（He 模式）的常规操作相结合，可为高通量实验室的高基质样品分析提供更高的效率。

Product Details
- 由安捷伦设计、制造并提供技术支持，能够与 ICP-MS 主机巧妙地结合，并且具有完全集成的软件
- AVS MS 样品环用蠕动泵填充，而非隔膜真空泵，因此样品消耗很少（大约 2 mL/min），不存在真空泵及其相关的泵阀磨损及更换问题
- 该系统可完全兼容 Agilent SPS 4 自动进样器
- AVS MS 能够显著提高样品通量，总运行时间不超过 1.5 分钟（取决于元素列表和样品类型），这一耗时仅为常规（连续）进样系统的 1/3-1/2
- 减少接口在样品基质中的暴露时间，从而减少信号漂移，提高短期和长期精度，同时降低采样锥的清洗频率
- AVS MS 可以与安捷伦高基质进样系统附件技术相结合，以快速分析总溶解态固体含量在百分级的样品。与 ICP-OES 相比，其检出限更低，而且不受干扰影响，这一切都要归功于不连续进样的效率。

High Throughput Analysis of Rock Digests using the 7700x with HMI and ISIS-DS
Geological exploration and mining generate tens of thousands of samples per week worldwide which must be analyzed quickly and accurately for a wide range of metals. By combining the High Matrix Introduction (HMI), which is standard on the Agilent 7700x ICP-MS, with Agilent’s Integrated Sample Introduction System for Discrete Sampling (ISIS-DS), previously unachievable throughput and stability can become routine. Sample throughput can be increased 4-fold while reducing the matrix load on the plasma and interface by more than 90% compared to conventional ICP-MS.
