VGA 77 Vapor Generation Accessory

The Agilent VGA 77 is a continuous-flow vapor generation accessory for atomic absorption (AA) instruments that determines Hg and the hydride-forming elements at parts per billion (ppb) levels. A VGA 77P is also available for use with inductively coupled plasma optical emission spectroscopy (ICP-OES) instruments.The entire plumbing assembly is integrated into a separate module and can be easily exchanged when switching elements. The VGA 77 can be coupled with the ETC 60 (AA instruments only) and the SPS 4 autosampler to enable unattended hydride analyses. This combination can be also used with the Agilent Zeeman graphite furnace AA instruments.
