OHAA-810 Atomic Absorption Spectrophotometer
A single-flame atomic absorption spectrophotometer built for high-throughput, cost-sensitive labs needing reliable trace metal quantification, reflecting a maturing domestic supply chain for core analytical instruments.
The OHAA-810 is a single-beam atomic absorption spectrophotometer optimized for routine flame-based elemental analysis. It targets laboratories where the priority is dependable, repeatable quantification of metals like copper, not the flexibility of a combined flame and graphite furnace system.
Its design is straightforward. An 1800 lines/mm grating monochromator and photomultiplier tube detector cover a 190-900nm wavelength range. The air-acetylene flame, fed by a high-efficiency glass atomizer, delivers a copper detection limit of 0.003 µg/mL and repeatability under 0.6% RSD.
Operationally, the instrument removes friction for routine workloads. It supports simultaneous preheating of up to eight hollow cathode lamps and includes automatic ignition. Safety monitoring—covering gas pressure, flame state, and waste liquid levels—is integrated, reducing the need for constant operator vigilance.
The accompanying software automates signal acquisition, standard curve plotting, and report generation. For a lab processing dozens of samples daily, this automated data pipeline cuts manual calculation errors and turnaround time.
Where this product sits in the supply chain is instructive. It competes with established Japanese and German brands on price, but its component choices—a 10cm titanium burner head, deuterium lamp background correction—point to a domestic ecosystem capable of sourcing or producing high-performance subassemblies.
For procurement managers at environmental testing labs, food safety centers, or mining quality control facilities, the OHAA-810 represents a shift: capable, dedicated flame AAS no longer requires a premium import budget. The optional hydride generator extends its reach to arsenic and selenium analysis.
The OHAA-810 is not a breakthrough invention. It is a refined, purpose-built tool that signals how far China’s analytical instrument manufacturing has come in closing the gap on usability and reliability for the global routine analysis market.
Why it matters:
For labs where the majority of metals testing is flame AAS, this instrument offers a cost-effective path to regulatory compliance without sacrificing repeatability. Its safety automation and data management features reduce total cost of ownership by minimizing operator time per sample.
