PF3/5/7 series universal atomic fluorescence spectrophotometer

PF3/5/7 series universal atomic fluorescence spectrophotometerBy adopting gas source sequential flow injection technology, dual beam optical structure, and information-based sample management system, the problem of poor durability of peristaltic pumps has been solved, and the problem of poor stability of super-resolution analysis instruments has been improved. This has achieved the construction mode of atomic fluorescence product technology without peristaltic pump maintenance and dual beam calibration.

Features:

√ Maintenance free
1. A pneumatic flow system without wear parts eliminates the maintenance troubles of peristaltic pumps.
2. The syringe uses pure water medium to solve the problem of damage to measuring instruments caused by acid and alkali solutions.
√ Non adjustable
1. Plug and play element lamp technology, no manual adjustment required for lamp replacement, good lamp position accuracy, and reliable detection results.
2. The height of the quartz furnace atomizer is automatically set to the working area without visual adjustment, which is convenient and fast.
√ More stable
1. The dual beam single detector optical system effectively reduces the drift and fluctuation of the excitation light source, and has good stability in mercury testing.
2. Pneumatic flow path system, constant pressure and constant flow, small sample deviation, and small differences in long-term testing of the same sample.
3. It can achieve online, reverse, and multiple cleaning, with minimal sample residue and the ability to test high concentrations.
4. Vapor liquid separator for cooling, water removal, stirring and mixing to improve sensitivity.
√ More environmentally friendly
1. Adopting the exhaust gas enclosed diversion technology, the exhaust gas is discharged outdoors after adsorption treatment through the diversion channel, ensuring the safety and environmental protection of the analysis work.
2. Sealed storage of waste liquid reduces volatilization, has overflow alarm, and is safer to use.
√ More applicable
1. It can quickly connect morphological analysis units to form an atomic fluorescence morphological analyzer.
2. Can be connected to large injection volume trace element testing accessories to meet the testing needs of users for ultrafine content samples.
3. Can connect micro injection attachments with small injection volumes to meet the needs of users for small injection volumes of samples.

PF3/5/7 series universal atomic fluorescence spectrophotometerprinciple
Ground state atoms absorb energy from the light source and become excited states. Excited state atoms release the absorbed energy in the form of fluorescence during the deactivation process. The strength of this fluorescence signal is linearly related to the content of the analyte in the sample. Therefore, the content of the analyte in the sample can be determined by measuring the fluorescence intensity.
