Instrument	Hydra II_AA	Hydra AF	Hydra AF_{Gold Plus}	Hydra-C
Usage	Primarily for liquid samples Determine Hg from low ppt to ppm levels	Primarily for liquid samples Determine Hg from sub ppt to high ppb levels	Primarily for liquid samples Determine Hg from 0.05 ppt to ppb levels	Primarily for solid samples Determine Hg in various matrices without sample preparation
Detection Limit	1 ppt	0.2 ppt	Less than 0.05 ppt	0.005ng
Dynamic Range	1 ppt - 1 ppm	0.0002 - 250 ppb	0.00005 - 250 ppb	0.005 - 1000 ng
Scientific Method	Chemical Reduction followed by Atomic Absorption	Chemical Reduction followed by Atomic Fluorescence		Thermal decomposition followed by amalgamation and atomic absorption
Gas/Liquid Separation	Leeman-designed gas-liquid separator provides exceptional sensitivity and recoveries, even for samples that foam during the reduction step			N.A.
Software Interface	Hydra’s software provides ease-of-use and compatibility with other MS-Windows® applications including Word, Excel, and Access. It also permits custom report generation and data manipulation, as well as connectivity to most LIMS systems
Features	Dual beam detection system 30cm optical cell provides exceptional sensitivity and stability, 1 cm optical cell provides access to high concentration Hg measurements High sample throughput for improved productivity and low cost of analysis Easy access sample introduction system Continuous flow-through rinse minimizes sample carryover, even at ultra-low levels High concentration protection system High capacity auto sampler Upgradable to direct sold anaysis (Hydra-C)	Proprietary fluorescence optical cell High sample throughput for improved productivity and low cost of analysis Counter-flow Nafion® membrane dryer minimizes water vapor-based scatter in the fluorescence cell Continuous flow-through rinse minimizes sample carryover, even at ultra-low levels High concentration protection system	Proprietary fluorescence optical cell High sample throughput for improved productivity and low cost of analysis Counter-flow Nafion® membrane dryer minimizes water vapor-based scatter in the fluorescence cell Continuous flow-through rinse minimizes sample carryover, even at ultra-low levels High concentration protection system Dual fluorescence detectors provide unparalleled working range from sub ppt to high ppb Ultra trace analysis mode with dual gold amalgamation traps for improved performance at sub-part-per-trillion levels	Analysis in 5 minutes Easy access maintenance Green chemistry/ no chemicals needed & no hazardous waste produced Applicable to both solid & liquid samples
