Hydra II TELEDYNE LEEMAN LABS A Teledyne Technologies Company

The Hydra II Family of Mercury Analyzers Al Teledyne Leeman Labs, atomic spectroscopy is our business - our only business. We are industry leading innovators wiih a proven track record providing Systems tha delrver outstanding performance, robustness and operational simplicrty. Teledyne Leeman Labs Hydra sries mercury analyzers were Ihe first to offer 'lurnkey' op響ration for the Hg analysis techniques: (1) rduction with cold vapor atomic absorption (CVAA) dtection, (2) r驩duction with cold vapor atomic fluorescence (CVAF) dtection and (3) thermal dcomposition with cold vapor atomic absorption...

ffycfra // Sample Digestion Cold Vapor Atomic Absorption (CVAA) The Hydra IIaa The Hydra llM employs the most widely used mercury atulysis technique: sample digestion followed by cold vapor atomk absorption (CVAA). Thrs technique's popularity is in its ability to deliver both sensitivity and selecbvrty needed to meet or exceed the reqiirements of many US and EiFopean standard melhods. Wrth its ppt dtection capabilrty, exceptional stability and powerful over-range protection system. the most stringent QCs can be satisfied while rfs high capadty autosampler assures a long period of unattended opration....

Analyzing Many Sampies is Easy The HydraIIautosampler rs designed for the ftedblity needed to take advantage of the system's fast analysis speed as well as to accommodate the use of a wide variety of low cost sample cups. It has two large rservoirs for recuring QCs, induding CCVs and CCBs, wrth enough capacity for a complte automated run without operator intervention. A ivkfe variety of commermly avaibUe sample at>s are swported to adeve maximum productivity and to ensure Difficult Sampies Made Simple The novel gas/liqukl separator ensures that sampies prone to foaming such as municipal wastewater...

Hydra // Sample Digestion Cold Vapor Atomic Fluorescence The Hydra IIaf and af Gold With the drive to routinely adiieve sub ppt dtection of mercury, anafysts are increasingly tuming to cold v^por atomic fluorescence (CVAF) vrfikh is inherentty a more sensrtive technique than CVAA. To meet that challenge, Teledyne Leeman Labs developed the Hydra llF and Hydra Uafc*m Systems. The Hydra II& uses cold vapor atomk fluorescence d邩tection for the measurement of mercury to 0.1 ppt or lower. The Hydra IIafc*m adds a pre-concentration stage using gold amalgamation prior to dtection yielding dtection levels...

Exceptional Linearity An attractive characteristic of atomic fluorescence is its linear range. The chart to the right shows a linear response for the Hydra IIAF that extends to 5 orders of magnitude. The benefit to the analyst is that samples with higher concentrations can be measured without additional dilution. Sensitivity for the Most Demanding Methods This chart shows signal enhancement using the Hydra IIAF Gold to pre-concentrate 12mL of sample prior to analysis. If more sample is pre-concentrated the enhancement increases. EPA Method 1631 employs pre-concentration while EPA Method 245.7...

Direct Analysis of Solids and Semi Solids The HydrallC The Hydra llC is a fully automated analyzer that measures mercury in solid and semi-solid sample matrices directly without any acid digestion (sample preparation). It employs the technique of sample combustion (thermal decomposition), mercury concentration via gold amalgamation and detection by cold vapor atomic absorption. The biggest advantage of the Hydra llC is that no sample preparation is required. And, because no sample prep is required, no hazardous waste is generated that would have to be disposed of safely and with high cost. Principle...

Matrix Independent Calibration A key benefit of the thermal decomposition process is its ability to report accurate results regardless of differences in sample matrix, Figure 1. Figure 2 shows the system accuracy for a diverse variety of sample types all obtained from a single aqueous calibration curve. Alternatively, certified reference materials may be used as standards to calibrate the system. Figure 1 Figure 2 Sdiment Ci u S - O Coal < Dogfish y/* t<飩i--- Oyster Taste Concentration SAMPLE NO.

Software - Powerful Yet Easy-to-Use Instrument Control is fully automated and appears on a single screen. The graphical display helps operators to understand how the system functions. System parameters are automatically stored and can be recalled at any time to satisfy audit requirements. On start-up, simply clicking the start button returns all system conditions to the last setting saved with the method. 'On-the-fly' Sample Programming saves valuable time by allowing the operator to start a sample squence even if individual sample entries are not yet complete. Samples can be easily located,...
