| Optical System |
| High light throughput single beam and true double system. The unit 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 smoothy with this instrument, if the stored default methods are aplplied. In case of unique challenges our application experts will take personal responsibillity for responding to the customer”s needs. |
| Monochromator | Czerny-Turner-type with 2 focal lenghts at 355.8 and 345.6 mm, automated wave lenght selection and slit selection. The system provides a true double beam mode. |
| Wavelenght range | 185-900 nm |
| Mode of operation | Automatic Absorption and atomic Emission |
| Grating | Holograpic grating with 1800 lines/mm |
| Detector | with range UV sensitif photo multiplier tube |
| Slits | Automatic slit selection 0,1;0.2;0.7;1.4 and 2.0 nm |
| Lamp | Automated 8-lamp turred with independent lamp power supply to each lamp and with two heating circuit for preheating lamp operation. |
| Background Correction | Deuterium (D2) Background Correction and Smith-Hieftje (Selt Absorption) Background correction. |
| Flame System |
| Burner-Nebulizer System | All-Titanium 100 nm and 50 nm burners are available for air/acetylene gases and for acetylene/nitrous oxide flame. Adjustable nebulizer with internal platinum/Iridium capillary, PEEK Nozzel and fixed ceramic impact bead are supplied as standart. The unit feature automatic setting of burner height for each elemant. |
| Spray Chamber | The PPS (Pholyphenyllene Sulfid) Spray Chamber is use for both aqueos and organik solution. |
| Gas Controls | Sofware controlled gas box allows the automatic setting of gas flows for each element. Acetylene flow is automaticaally adjusted prior to the oxidant change with switching to or from nitrous oxide-acetylene operation. |
| Savety Function | Interlocked safety system prevent selection of the nitrous oxide flame if the nitrous oxide burner is not fitted. Sensor controls for protection to use in the incorrect burner head and check the siphon system. In case of pressure failure of fuel or oxidant gas, or power failure, safety interlock will shut down the gasses authomatically in the right order. |
