Product Introduction
Research institutions and professional quality control laboratories routinely face the challenge of characterising the full alkali and alkaline earth metal profile across diverse sample matrices — from geological digests and ceramic raw materials to pharmaceutical intermediates and environmental monitoring samples. Conventional approaches require either multiple single-element instruments or expensive ICP-OES systems that are disproportionate to the analytical task. The HM-FP5 Flame Photometer bridges this gap by integrating five independent detection channels — potassium, sodium, lithium, calcium, and barium — into a single benchtop platform that delivers the complete element profile from one aspiration event.
Built on decades of flame emission spectroscopy expertise, the HM-FP5 employs dedicated interference filters for each channel, paired with silicon photocell detectors that provide direct concentration readout without mathematical cross-correction. The 7-inch color capacitive touch LCD replaces traditional knob-and-dial controls with an icon-driven interface that displays real-time results, calibration status, and instrument diagnostics simultaneously. This modernised approach reduces operator training time from days to hours while maintaining the analytical rigour expected by accredited laboratories.
The self-developed high-performance nebulizer is engineered for consistent aspiration below 6 mL/min, ensuring stable flame conditions and reproducible results even when processing hundreds of samples in a single session. One-touch ignition with a built-in air pump removes external compressor dependency, keeping the bench footprint compact at 460 mm × 325 mm × 450 mm. For laboratories managing multiple sample types, the calibration system supports up to 10 points per element across 20 stored curves, with segmented, linear, and curve fitting modes enabling rapid method switching between protocols — for example, from dilute environmental water samples to concentrated ceramic digest solutions.
Data integrity is ensured through dual-path documentation: a built-in thermal printer generates instant hard-copy records, while USB drive export enables seamless integration with laboratory information management systems (LIMS) and electronic quality records. Flame-out protection with automatic gas valve shutoff and a moisture separator for environmental stability make the HM-FP5 suitable for unattended batch operation. Compliance with JJG630-2007 and multiple industry standards supports accreditation documentation. Discover the full capabilities of our five-element flame photometer platform for your laboratory's analytical requirements.

FAQ
The HM-FP5 adds a fifth detection channel for barium (Ba) alongside the standard potassium, sodium, lithium, and calcium channels. This fifth channel is critical for laboratories working in ceramic and glass raw material analysis, where barium content directly affects melting temperature and optical properties, as well as environmental monitoring near drilling and mining operations where barium is a regulated contaminant. The complete five-element profile from a single aspiration eliminates the need for a separate barium-specific instrument or an expensive ICP-OES system, providing a cost-effective solution for comprehensive alkali and alkaline earth metal characterisation.
Research laboratories often work with diverse sample types — from dilute environmental water samples to concentrated acid digests of geological and ceramic materials. The HM-FP5 addresses this variety through its flexible calibration system: up to 10 points per element across 20 stored curves, with three calculation modes (segmented, linear, and curve fitting) that accommodate both linear and non-linear calibration behaviour. Operators can maintain separate calibration sets for different matrices and switch between protocols via the touchscreen without re-standardising. The self-developed nebulizer's stable aspiration below 6 mL/min ensures consistent flame conditions regardless of matrix complexity, while single-point recalibration corrects baseline drift between extended analytical sessions.
The HM-FP5 provides dual-path data documentation to support both paper-based and electronic quality management systems. A built-in thermal printer generates instant hard-copy records of every measurement, including element concentrations, calibration parameters, and timestamps. For digital archiving, all historical records can be exported via USB drive to a computer or laboratory information management system (LIMS). The 7-inch touchscreen displays real-time results alongside calibration curve status, allowing operators to verify data quality during acquisition. This combination of physical and digital documentation satisfies the audit trail requirements of ISO/IEC 17025 accredited laboratories and regulatory inspection bodies.
