Overview
The FP640 Flame photometer is a professional analytical instrument of JINGQI brand. It adopts Interference filter working mode and is equipped with LED LCD screen display. The instrument has High Accuracy detection capability, the sample absorption and spray volume is less than 6mL/min, the stability is not more than 3% within 15 seconds, not more than 5% within 5 minutes, and the Response Time is less than 8 seconds. The detection limit is potassium ≤ 0.004mmol/L, sodium ≤ 0.008mmol/L, sexual repeability ≤ 3%, linear error potassium ≤ 0.005mmol/L, sodium ≤ 0.03mmol/L. The test range is 0~ 100ug/ml for potassium and 0~ 160ug/ml for sodium.
Features
1. Dual-channel proportional value display
2. The reading can display the decimal point
3. Knob operation
4. Flame size pre-selected
5. With flameout protection device
Principle
The FP640 Flame photometer is based on the Interference filter technology to separate the specific wavelength rays of light for elemental analysis. The absolute value of the peak wavelength error of the potassium filter is ≤ 7nm, the half width is ≤ 15nm, and the background transmittance is ≤ 0.5%; the absolute value of the peak wavelength error of the sodium filter is ≤ 5nm, the half width is ≤ 15nm, and the background transmittance is ≤ 0.5%. The instrument measures the concentration of potassium and sodium elements in the sample to achieve fast and accurate detection.
Applications
Pottery and porcelain, cement, Glass, soil and fertilizer, clinical, refractory, third-party testing, professional colleges
Steps
