Overview
FSP series multi-element Flame photometer (model FSP6641) is an instrument that adopts a concave Holographic grating multi-channel management structure to realize multi-element simultaneous measurement. Compared with the filter system, its wavelength is accurate, the passband is narrow, and the Sensitivity is high. Zero-level light can be selected to collect flame energy changes as an internal standard, making the measurement data more stable and reliable. The instrument is equipped with a 5.6-inch true color high-resolution wide viewing angle display and touch screen, which is user-friendly to operate.
Features
1. Concave Holographic grating design.
2. The five elements can be combined in any way and directly read the measurement at the same time, and the software selection is flexible and convenient.
3. Imported Photocells, photovoltaic cells receive element signals, stable and reliable performance.
4. With an internal standard channel, it is corrected with a signal that does not contain measurement elements, and the measurement is synchronized with the elements.
5. The internal standard correction is designed to be optional and can be freely selected according to the situation.
Adopting a 5.6-inch color 640 × 480 display screen and a matching touch screen, man-machine integration is harmonious.
7. With automatic ignition, including flame monitoring, with flameout protection and alarm to ensure safety.
8. Switching power supply, light weight, small size, low heat generation, small impact of external power supply, energy saving and environmental protection.
Principle
The instrument is based on the flame Spectrophotometric method, spec-trophotometry principle. The sample solution enters the flame after atomization, and the elements to be measured are excited in the flame to emit characteristic spectral lines of specific wavelengths. The instrument uses concave Holographic grating for spectroscopy to separate the characteristic light of different elements, and is received and converted into electrical signals by imported photocells and photovoltaic cells for measurement. You can choose to use zero-level light to collect flame energy changes as internal standards to synchronously correct the measurement signal to improve the Stability and Reliability of the data.
Applications
Chemical industry, environmental protection, food, medicine, agriculture, geology, metallurgy, scientific research and education
Steps
1. Turn it on and warm up, check the gas circuit connection.
2. Start the instrument software, select the combination of elements to be tested and whether to enable internal standard correction.
3. Perform automatic ignition, and the instrument enters the flame monitoring state.
4. Linear dispersion calibration using standard solution (Linear dispersion fitting method).
5. Introduce the sample solution to be tested for measurement, the instrument reads directly and displays the results.
6. After the measurement is completed, you can connect the printer to output data or communicate with the computer through the USB port as needed.
Notice
• Please ensure that the air source is connected correctly and free of leakage before use.
The working environment temperature of the instrument should be kept at 0~ 35 ℃.
• During the ignition and measurement process, do not touch high temperature parts such as combustion heads.
• The instrument has the function of extinguishing the flame. If the flame is accidentally extinguished, it will alarm. Please find out the reason before operating.
• Regularly maintain Nebulizer, combustion head and other components to ensure instrument performance.
• Please calibrate with a standard solution that meets the requirements.
