Optical Emission Spectrometer
Application Field
LR-8681 is a full-spectrum direct-reading inductively coupled plasma emission spectrometer for the determination of trace and trace elements in different substances (dissolved in nitric acid, กรดไฮโดรคลอริก, กรดไฮโดรฟลูออริก, ฯลฯ). It is widely used in environmental protection, ผลิตภัณฑ์ปิโตรเลียม, rare earth, semiconductor, geology, โลหะวิทยา, อุตสาหกรรมเคมี, clinical medicine, อาหาร, biological samples, criminal science, agricultural research and other fields.
ลักษณะการทำงาน
Performance stability
The use of all-solid-state rf power supply, with small size, ประสิทธิภาพสูง, stable output power, with a variety of protection
functions and many other advantages, the load using fully automatic matching technology, matching speed, improve the efficiency of the use of power supply and the stability of the instrument, and make the whole ignition process simple and convenient.
Adopting four-channel automatic design, the rotational speed can be set up according to the test demand to adjust the flow rate, carrier gas, plasma gas, auxiliary gas are all controlled by advanced mass flow controller, at the same time can be equipped with imported high salt nebulizer, imported hydrofluoric nebulizer and so on to meet the customer’s various test needs.
Precision analysis
The middle step grating prism cross dispersion mode is adopted, there is no moving optical element, the ultra low stray light design is combined with the unique optical design, nitrogen distributed blowing, imported optical elements, intelligent and accurate automatic wavelength calibration algorithm.
