PF5/PF7Series atomic fluorescence spectrophotometerOn the basis of the existing technology of atomic fluorescence spectrophotometer, a series of technologies such as dual beam, sequential flow injection of gas source, and efficient water removal have been added, forming two series of multi model products with stable performance, comfortable operation, and safety and environmental protection to meet the needs of different users. apply toAs、Se、Pb、Bi、Te、Sn、Sb、Hg、Cd、Zn、GeThe daily trace analysis of eleven elements can be widely applied in fields such as food hygiene, environmental monitoring, cosmetics inspection, medicine and health, agricultural environmental protection, geology and metallurgy. |
PF5/PF7Series atomic fluorescence spectrophotometermain features |
|
√maintenance-free A pneumatic flow system without wear and tear parts, * eliminating the maintenance troubles of peristaltic pumps; The syringe uses pure water medium to solve the problem of damage to measuring instruments caused by acid and alkali solutions. √Debugging free The adjustable element lamp ensures that each element lamp works in the * state, avoiding deviations caused by human factors; The quartz furnace atomizer automatically sets the working area without visual adjustment, making it convenient and accurate. √more stable The dual beam single detector optical system effectively eliminates the drift and fluctuation of the excitation light source, and the long-term stability of mercury testing is less than10%； Pneumatic flow path system, constant pressure and constant flow sample deviation is small, long-term testing, and the accuracy of testing the same sample is better than5%； It can achieve online, reverse, and multiple cleaning, with minimal sample residue and the ability to test the highest concentration compared to existing technologies2Double; Vapor liquid separator, cooling water removal, stirring and mixing, with improved sensitivity compared to existing technologies30%. √GREENER The exhaust gas emission system with fully enclosed furnace barrels and independent outlets can be connected to multi-stage exhaust gas treatment accessories, ensuring safety and environmental protection; Sealed storage of waste liquid reduces volatilization, has overflow alarm, and is safer to use. √More applicable Can quickly connect morphological analysis units to form an atomic fluorescence morphological analyzer; Can be connected to high injection volume trace element testing accessories to meet the testing needs of users for ultrafine content samples; Can connect micro injection attachments with small injection volumes to meet the needs of users for small injection volumes of samples. |
