HM-FP2 Flame Photometer

Product Introduction

The HM-FP2 flame photometer is a compact, entry-level analytical instrument designed for the quantitative determination of potassium (K) and sodium (Na) concentrations in liquid samples. Based on the well-established atomic emission spectroscopy principle, the HM-FP2 atomizes sample solutions in a controlled flame and measures the characteristic emission intensity at element-specific wavelengths using high-transmittance interference filters and silicon photocells.

Equipped with a 7-inch color capacitive touch LCD, the HM-FP2 provides an intuitive user interface for direct concentration readout, calibration curve management, and data export. The instrument features two independent detection channels for simultaneous K and Na measurement, eliminating the need for sequential testing and significantly improving laboratory throughput. Its built-in air pump and one-touch ignition system remove the dependency on external compressed gas sources, making installation straightforward in any laboratory environment. The integrated thermal printer and USB data export capability ensure complete traceability for quality management systems.

Applications

• Environmental Monitoring: Determination of potassium and sodium in surface water, groundwater, and wastewater samples
• Agricultural Soil Analysis: Measurement of available potassium and exchangeable sodium in soil extracts per NY/T889-2004 and LY/T1246-1999 standards
• Food & Beverage Industry: Sodium content analysis in processed foods, beverages, and dairy products for nutritional labeling
• Chemical Manufacturing: Quality control of raw materials and finished products requiring alkali metal concentration verification
• Clinical & Biomedical Labs: Electrolyte analysis in serum and urine samples for potassium and sodium levels
• Geological Survey: Determination of alkali metal content in rock and mineral leachate samples

Functional Performance

1. 7-inch capacitive touch LCD — compact, stable, and reliable operation with intuitive menu navigation
2. 2-channel direct reading — simultaneous potassium and sodium concentration measurement in a single aspiration
3. High-transmittance interference filters — ultra-low stray light design for higher signal-to-noise ratio and improved accuracy
4. One-touch ignition with built-in air pump — no external gas source needed, reducing installation complexity and operating costs
5. Self-developed high-performance nebulizer — uniform nebulization with smooth, stable aspiration at less than 6 mL/min sample consumption
6. Up to 10-point calibration curves — 20 curves stored for different analytical methods, supporting segmented, linear, and curve fitting
7. Moisture separator — prevents environmental humidity from affecting measurement results
8. Flame-out protection — automatic gas solenoid valve shutoff upon flame extinction for operator safety
9. Single-point calibration — quick correction for baseline drift during extended testing sessions
10. Thermal printing and USB export — historical record printing and USB drive data export for traceable data management
