Description :

LB-AFS680 atomic fluorescence spectrophotometer

Product Introduction

　　The LB-AFS680 adopts a semi transparent and corrosion-resistant ABS magnetic structure for the instrument front door, which avoids the interference of external air circulation and allows for online observation of the chemical reaction during the testing process. By using a split signal control module on the circuit, even if there is a significant difference in the concentration of the two elements measured in the sample, there can still be no inter channel interference when measuring simultaneously in two channels. Especially suitable for testing departments with large sample sizes and simultaneous dual channel measurements. Widely used in teaching research, health and epidemic prevention, medical clinical testing, drug inspection, food hygiene inspection, urban water supply and drainage inspection, agricultural product inspection, beverage inspection, environmental monitoring, cosmetics inspection, metallurgical sample inspection, geological survey and testing industries.

　　Comprehensive injection control functions such as continuous flow injection and intermittent injection.

　　Real time observation of the testing process and online adjustment of the three-dimensional parameters of the atomizer.

　　The pressure self balancing waste liquid removal function does not require additional pumps for waste discharge.

　　Small background deduction function.

　　Friendly software interface, recommended instrument testing conditions, graphical display and playback of test data, statistics and queries, various functions such as saving, outputting, backing up and printing of graphics and data pages. Suspended measurement window, increasing the amount of information that can be displayed (fluorescence intensity, blank values, etc.).

　　Instrument self check and gas cut-off warning protection function.

　　It can seamlessly integrate with liquid phase and online digestion units to achieve morphological analysis of elements such as arsenic, mercury, and selenium.

　　Dual channel two elements can be measured simultaneously, suitable for trace analysis of twelve elements including arsenic, mercury, selenium, tin, lead, bismuth, antimony, tellurium, germanium, cadmium, zinc, gold, etc. in samples

　　The hollow cathode lamp adopts a new pulse modulation/constant current drive power supply method

Technical Specifications

　　Sample atomization
