| General Features: | |
| 1) The instrument is capable of measuring three elements at the same time among five elements including Na, K, Li, Ca and Ba; | |
| 2) The series of product is comprehensive and the end user can use it directly with preparing gas source of propane, butane and petroleum gas only; | |
| 3) Application areas: beverage, chemical manufacturing, clinical detection, agriculture, food detection, mineral extraction, oil industry, petroleum, chemical industry and soil analysis. | |
| Structural Characteristics: | |
| 1) Five filters (Na, K, Li, Ca, and Ba) are equipped with five-channel detection function. Three elements can be detected at the same time and the content of three elements can be displayed as well. | |
| 2) The touch panel has number keys. | |
| 3) Single point calibration. The calibrated curve can be saved in the device. | |
| 4) RS232 interface. The device is able to connect extension equipment, such as, computer and printer. | |
| 5) A mist separator is provided. | |
| Technical Characteristics: | |
| 1) Linear processing: each of the five elements can be processed with the application software; and single point calibration is prepared. | |
| 2) Sample injection rate: 4-6ml/min | |
| 3) The best measurement range: | |
| Na: 0 - 100ppm; | |
| K: 0 - 100ppm; | |
| Li: 0 - 100ppm; | |
| Ca: 0-1000ppm; | |
| Ba: 0 - 3000ppm; | |
| 4) Repeatability: when the equipment is stable for about 30mins, the deviation factor is not higher than 3% (the concentration of sample is 100ppm or even less); | |
| 5) Detection limit: | |
| Na: 0.01ppm; | |
| K: 0.01ppm; | |
| Li: 0.025ppm; | |
| Ca: 0.1ppm; | |
| Ba: 10ppm; | |
| 6) Time stability: less than 15s (after the sample is burnt in the flame); | |
| 7) Drifting: ≤3% (when the equipment is stable for about 30mins); | |
| 8) Linear: better than the median value of optimal result by 2% (single point calibration); | |
| 9) Two linear calibration methods: subsection method, and quadric fitting method; | |
