From an acquisition standpoint, Vector/2 and EnviroLink are nearly identical. Instrument tuning, calibration and data acquisition are essentially the same. A few instrument control parameters are hidden in the EnviroLink system aiding good laboratory practices for testing laboratories. Vector/2 has its own native processing, library and quantitation packages. EnviroLink, as a derivative of Vector/2, was introduced to take advantage of the HP ChemStation quantitation package. EnviroLink was introduced to target the environmental testing market. Currently, EnviroLink and Vector/2 normally ship with copies of HP (Agilent) ChemStation unless the purchaser specifies otherwise.
