High light throughput Single Beam and True Double Beam. The SP-AA 4000 is a fully automated computer controlled Flame AAS instrument featuring an 8-lamp turret, automatic gas box and automatic burner height setting. The majority of samples will run smoothly with this instrument, if the stored default methods are applied. In case of unique challenges our application experts will take personal responsibility for responding to the customer”s needs.
Czerny-Turner- type with 2 focal lengths at 355.8 and 345.6 mm, automated wavelength selection and slit selection. The system provides a true double beam mode.
185 – 900 nm
Modes of Operation
Atomic Absorption and Atomic Emission
Holographic grating with 1800 lines/mm
Wide range UV sensitive photomultiplier tube
Automated 6 slit selection 0.1; 0.2; 0.5; 0.7; 1.4 and 2.0 nm
Automated 8-lamp turret with independent lamp power supply to each lamp and with two heating circuits for preheating lamp operation
Deuterium (D2) Background Correction and Smith-Hieftje(Self-absorption)Background Correction.
All-titanium 100 mm and 50 mm burners are available for air / acetylene gases and for acetylene / nitrous oxide flame. Adjustable nebulizer with internal Platinum / Iridium capillary, PEEK Nozzle and fixed ceramic impact bead are supplied as standard. SP-AA 4000 features automated setting of burner height for each elements.
The PPS (Polyphenylene Sulfide) spray chamber is used for both aqueous and organic solution
Software controlled gas box allows the automatic setting of gas flows for each element.Acetylene flow is automatically adjusted prior to the oxidant change when switching to or from nitrous oxide-acetylene operation.
Interlocked safety system prevents selection of the nitrous oxide flame if the nitrous oxide burner is not fitted. Sensor controls for protection to use the incorrect burner head and check the siphon system. In case of pressure failure of fuel or oxidant gas, or power failure, safety interlocks will shut down the gases automatically in the right order.
The Hydride system is a continious flow technique for Determine Hg, As, Se, Sb, Te, Sn, Bi
Range concentration analyse at ppb
The Hg will be Determin ed with the cold Vapour technique
The System has the gas flow control including two peristaltic pump for supplay the reagen, acid, and sample
