Varian公司开发出微量样本吸取技术

Varian公司(Palo Alto, CA, USA)开发了两种Omix微型吸取方法。一种无需真空SPE即可处理生物液体样本，将其直接输送至液体处理设备的尖端，另外一种是微型容量的96孔板，专门设计用于处理体积很小的样本。Omix 技术具有单块集成电路技术，能够高效吸取很小体积的样本，从而改进了样本分析处理的质量。

Omix微型吸取移液器吸嘴可以用于Tomtec(Hamden, CT, USA)的Quadra设备，免除了真空处理的需要，确保设备能够全自动运行。SPE第一次能够直接用于Quadra兼容的吸嘴，因为Omix单块集成电路介质具有双向、无障碍流体特性。这就意味着清洗工作十分简单，从而增加了工作效率。

Streamlining Sample Preparation
 
Two Omix micro-extraction formats were developed by Varian, Inc. (Palo Alto, CA, USA). One enables vacuum-free SPE processing of biofluid samples directly in the tip of a liquid-handling device, while the other is a micro-volume 96-well plate specifically designed to process small sample volumes. The Omix technology features monolithic sorbent technology that allows for highly efficient extractions performed with low elution volumes, which improves sample throughput and analytic quality.

The Omix micro-extraction pipette tips for the Quadra instruments of Tomtec (Hamden, CT, USA) eliminates the need for vacuum processing and allows the instruments to be used in a fully automated capacity. For the first time, SPE can be performed directly in the Quadra compatible pipette tips, due to the bi-directional, clog-free flow properties of the Omix monolithic media. This means clean-up is simplified and reproducibility is improved.
