HM-FP3B Flame Photometer

Product Introduction

The HM-FP3B Flame Photometer is a high-performance three-channel analytical instrument engineered for simultaneous determination of potassium, sodium, and lithium concentrations. Utilizing atomic emission spectroscopy with interference filter spectral separation and silicon photocell detection, it delivers direct concentration reading with exceptional stability and repeatability. The 7-inch color capacitive touch LCD provides an intuitive interface for operation, calibration management, and data review. A self-developed high-performance nebulizer ensures consistent sample atomization, while the one-touch ignition system with built-in air pump simplifies daily operation. The instrument supports up to 10-point calibration curves with 20 stored curves, offering flexible quantitative analysis for geological survey, lithium battery material research, and clinical electrolyte profiling. Safety features include flame-out protection with automatic gas valve shutoff and a moisture separator for environmental stability. Historical records can be printed via the built-in thermal printer or exported through USB drive. Compliant with JJG630-2007 and soil/plant analysis standards, the HM-FP3B provides reliable alkali metal determination with faster turnaround than AAS for routine screening workflows.

Expert Review

The HM-FP3B stands out as a versatile mid-range flame photometer that bridges the gap between basic sodium/potassium analyzers and full-featured laboratory instruments. Its addition of lithium detection in a 3-channel configuration makes it particularly valuable for geological survey teams and battery material researchers who require routine alkali metal screening without the complexity and cost of AAS or ICP-OES systems. The self-developed nebulizer and interference filter system deliver reliable precision (repeatability ≤2%, stability ≤3% in 15 seconds), while the 7-inch touch LCD and one-touch ignition streamline daily operation. With compliance to JJG630-2007 and multiple soil/plant analysis standards, the HM-FP3B offers a cost-effective solution for laboratories seeking simultaneous K, Na, and Li determination. For environmental water quality monitoring with barium detection, consider the HM-FP3C model.
