用于 ICP-MS 的安捷倫高級閥系統(tǒng) (AVS MS)
高級閥系統(tǒng) AVS MS
AVS MS 與安捷倫 ICP-MS 系統(tǒng)的 HMI 技術和使用單碰撞池模式（He 模式）的常規(guī)操作相結合，可為高通量實驗室的高基質樣品分析提供更高的效率。

Product Details
- 由安捷倫設計、制造并提供技術支持，能夠與 ICP-MS 主機巧妙地結合，并且具有完全集成的軟件
- AVS MS 樣品環(huán)用蠕動泵填充，而非隔膜真空泵，因此樣品消耗很少（大約 2 mL/min），不存在真空泵及其相關的泵閥磨損及更換問題
- 該系統(tǒng)可完全兼容 Agilent SPS 4 自動進樣器
- AVS MS 能夠顯著提高樣品通量，總運行時間不超過 1.5 分鐘（取決于元素列表和樣品類型），這一耗時僅為常規(guī)（連續(xù)）進樣系統(tǒng)的 1/3-1/2
- 減少接口在樣品基質中的暴露時間，從而減少信號漂移，提高短期和長期精度，同時降低采樣錐的清洗頻率
- AVS MS 可以與安捷倫高基質進樣系統(tǒng)附件技術相結合，以快速分析總溶解態(tài)固體含量在百分級的樣品。與 ICP-OES 相比，其檢出限更低，而且不受干擾影響，這一切都要歸功于不連續(xù)進樣的效率。

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.
