7650罐式自动进样器

7650 Canister Autosampler

The 7650 brings the automated analysis of MiniCans, Bottle-Vacs, and even large volume sampling canisters to a whole new level! Drawing upon the benefits of its predecessors, the
7650 is the first canister autosampler to facilitate the analysis of up to twenty, 1–1.4L canisters while maintaining samples in a completely closed and isolated state until required for analysis. This level of isolation greatly reduces the potential for carryover, making the 7650 an ideal choice for today’s soil gas laboratories. All samples, standards, and blanks flow through the same direct flow path, eliminating any problematic background level variations – a well-known challenge with rotary valve based autosamplers.

The 7650 features a reliable and precise pneumatic z-axis control along with minimal transfer line sample contact. The brief sample transfer process is immediately followed with a nitrogen flush to greatly reduce any sample contamination risk due to high sample concentrartions. The 7650 heated transfer line directly inserts into a MiniCan or Bottle-Vac canister via an ultra-compact MicroValve™ fitting, for absolutely zero unswept dead-volume.

当与7200预浓缩器配合使用时，7650成为当今现代化实验室的理想自动进样器解决方案，必须定期分析高浓度和低浓度样品。 了解有关7200的更多信息 使用新的MillionAir进行PPM到亚PPB水平分析的7650-M。

特征

● 高或低水平的分析

7650自动进样器具有独立的循环分析功能，或配对7200预浓缩器进行痕量分析。

● 分析多达20个1L MiniCans / Bottle-Vacs
7650在两个10位托盘中装有1 - 1.4L罐，样品间隔离远远超过旋转阀自动进样器。

● TrueSeal阀门兼容性

现在，在分析之前，通过简单地将MicroValve 连接到采样阀顶部，为您的罐使用流行的TrueSeal和Nupro阀门添加MiniCan自动采样。

● Silonite-D涂层入口管线

7650 1/16“加热进口管线直接插入罐的MicroValve，零死体积，安全的样品连接。 在转移到预浓缩器或GCMS期间最小化样品接触后，立即用UHP氦气或氮气冲洗入口管线。 残留量通常不到前一个样本浓度的百万分之一！

● 扩展的自动采样容量

使用7650自动进样器侧面的扩展端口分析多达18个额外的6L罐或Tedlar袋。 现在，您可以使用经过验证的“直接入口”可靠性来分析库存中的任何罐。
