Welcome to the next generation of ICP-MS. Engineered to deliver a level of stability, flexibility and performance never before seen in an ICP-MS instrument, PerkinElmer's NexION® 300 is the first truly significant and revolutionary industry advancement in recent years. The NexION 300 offers 3 modes of operation (Standard, Collision and Reaction) and can be quickly switched from 1 mode to another. So, every analysis can be performed on the same instrument. It's the only ICP-MS that lets you maximize productivity without compromising sensitivity or performance. And, for the first time ever, a single ICP-MS instrument offers both the simplicity and convenience of a collision cell and the exceptional detection limits of a true reaction cell.
