System Parameter and Performance Comparison Between Agilent 7697A and Agilent G1888A Headspace Samplers for USP <467>

Version 1

    Application Note



    The Agilent 7697A Headspace Sampler introduced onboard electronic pneumatics control and several instrument control enhancements to improve performance over earlier models of headspace units sold by Agilent, such as the Agilent G1888A Headspace Sampler. With this introduction came the addition of several method parameters that were not in earlier models. This technical overview will explain those differences and show that, with these new parameters, the 7697A Headspace Sampler gives similar or better resolution, precision, and accuracy as the G1888A Headspace Sampler. It will also provide data on comparative studies between the two instruments that show the 7697A Headspace Sampler meets the System Suitability requirements for USP Method <467>
