ZA4800

Rapid sequential flame model

• Sequential measurement of up to 12 elements from a single sample injection
• A new diffraction grating drive mechanism — up to ~30% faster than the conventional flame method (e.g. 6 elements / 20 samples: 48 min instead of 68 min, per the brochure)
• 8 lamps (turret), 4 lit simultaneously (versus 2 on the other three models) — shorter lamp stabilization time
• Dimensions 800 × 650 × 567 mm, weight 104 kg · power supply 115/220/230/240 V, 0,2 kVA (consumption up to 0,1 kW)
• Intended use: laboratories that routinely measure multiple elements per sample and need higher sample throughput

Details

• Applications: environment (wastewater/river/seawater, soil — heavy metals down to ppb levels), food (cereals, dairy products, beverages, additives — Na, K, Ca, Fe, Pb, Cd), agriculture (fertilizers, animal feed — K, Ca, Mg, with an optional hydride method for As/Se), energy (lead in gasoline, major and trace metals in lithium-ion battery materials), plating (major constituents and trace metals in baths, e.g. copper in a nickel bath), materials (impurities and toxic metals in paints, plasticizers, batteries, cellulose, bottle leaching), pharmaceuticals (residual catalyst and toxic metals)
• Elements: over 50 metals/metalloids via single-element hollow cathode lamps (Ag, Al, As, Au, B, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, Ge, Hf, Hg, In, Ir, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni, Pb, Pd, Pt, Rh, Ru, Sb, Sc, Se, Si, Sn, Sr, Ta, Te, Ti, Tl, V, W, Y, Yb, Zn, Zr) plus multi-element lamps (e.g. Ca-Mg, Cd-Pb, Cd-Zn, Cu-Fe-Ni, Fe-Mn-Ni, Cu-Fe-Mn, Cr-Cu-Mn, Cu-Mn-Si, Cr-Cu-Fe-Mn-Ni, Co-Cr-Cu-Fe-Mn-Ni)
• Flame accessories (ZA4000, ZA4300, ZA4800): High-Temperature Burner Head (for Al, B, Be, Ge, La, Nb, Si, Ta, Ti, V, W, Zr with an N₂O-acetylene flame), High Salt Burner Head (high-salt samples, resistant to aqua regia), Glass Atomizer Set, Heated Quartz Cell (with the hydride method), SSC-230 Flame Autosampler (up to 80 samples, up to 12 elements), HFS-4 Hydride Formation System (As, Se, Sb with NaBH₄), PFA Disperser (samples with HF), Micro-Sampling Kit (samples <0,5 mL), Mercury Analyzer (mercury, cold-vapor method)
• Graphite furnace accessories (ZA4000, ZA4700): several cuvette types (Pyro Tube CIIHR/DIIHR/HR, Graphite Tube HR, Cup-type cuvette HR), Dustproof Cover, LED furnace work lighting, Alternate Gas Unit (argon + oxygen for decomposing organic material), GA Autosampler PEEK Nozzle, OMEGA Platform (for large sample volumes), automatic dosing of up to 4 types of chemical modifiers; Independent Atomizer (independent flame/graphite atomizers) available only on the ZA4000 model
• Safety functions (flame models): automatic gas-leak check at ignition, automatic gas-supply shutoff when the flame goes out, flashback prevention (buffer tank method), flame monitoring (flame sensor), fuel and auxiliary gas pressure monitoring, burner high-temperature interlock, drain liquid level and cooling water flow monitoring
• Software: wizard measurement parameters, automatic instrument diagnostics (wavelength precision, baseline stability, sensitivity, repeatability), continuous monitoring (numerical data, working curve, instrument status), batch display of atomization profiles, Excel sample table import (Load Sample Table), QC functions (sample check, STD check, QC sample check, calibration curve check, recovery check)
