OI Analytical 4551A Purge-and-Trap Water Autosampler
The M4551A Purge-and-Trap Water Autosampler achieves results by automating VOC analysis of up to 51 samples. Vertical docking of the autosampler to the Eclipse 4660 Sample Concentrator means no extra benchspace is used. The removable, lightweight sample carousel makes sample loading and unloading easy, while its spiral design optimizes septum-piercing accuracy. With its proven, reliable sample handling system, the Model 4551A gets the job done, sample after sample.
