Overview
The YiDian Analytical FP6400A Flame Photometer is a benchtop atomic emission spectrometer designed for quantitative determination of alkali and alkaline earth metals—including sodium (Na), potassium (K), lithium (Li), calcium (Ca), and barium (Ba)—in aqueous samples. It operates on the principle of flame atomic emission spectroscopy (FAES): sample solutions are nebulized into a premixed air-propane or air-butane flame, where thermal energy excites metal atoms to higher electronic states; upon relaxation, characteristic wavelength photons are emitted and measured via interference filters and a photomultiplier tube (PMT) or solid-state detector. The FP6400A delivers high linearity (R² > 0.999 over typical calibration ranges), low detection limits (sub-ppm for Na and K), and excellent inter-day reproducibility (<2% RSD), making it suitable for routine quality control in clinical laboratories, environmental monitoring agencies, fertilizer testing labs, and food & beverage production facilities.
Key Features
- Stable dual-channel optical path design with independent PMT detectors for simultaneous Na/K measurement—eliminating sequential readout delays and minimizing flame fluctuation errors
- Adjustable air-gas flow control system with integrated pressure regulators and flashback arrestors compliant with EN 589 and ISO 8503-2 safety standards
- Pre-calibrated filter set (e.g., 589 nm for Na, 766 nm for K, 670 nm for Li, 422 nm for Ca) with ±0.5 nm bandwidth tolerance and OD > 4 blocking performance
- Integrated microprocessor-controlled ignition sequence with automatic flame-out detection and gas cutoff safety interlock
- Robust stainless-steel burner head with corrosion-resistant nickel-chromium alloy construction, rated for continuous operation up to 8 hours per shift
- RS-232 and USB-B interfaces supporting bidirectional communication with LIMS and third-party data acquisition software
Sample Compatibility & Compliance
The FP6400A accepts liquid samples with total dissolved solids (TDS) ≤ 0.5% w/v and viscosity < 5 cP. Dilute acid digests (e.g., HNO₃/HCl), filtered natural waters, serum/plasma extracts (post-deproteinization), soil leachates, and fertilizer solutions are routinely analyzed. Sample introduction is via precision peristaltic pump (flow rate: 3–5 mL/min) with optional autosampler integration (FP-AS12). Instrument compliance includes adherence to ISO/IEC 17025:2017 method validation requirements, ASTM D1292 (for sodium in water), ASTM D5084 (hydraulic conductivity-related cation analysis), and CLSI EP9-A3 guidelines for comparative method evaluation. All firmware and calibration protocols support audit trails required under GLP and GMP environments.
Software & Data Management
The FP6400A operates with YiDian’s FPMaster v3.2 analytical software (Windows 10/11 compatible), providing full CFR 21 Part 11 compliance through user-level access control, electronic signatures, and immutable audit logs. Key functions include multi-point linear/non-linear calibration (including internal standard correction), real-time background subtraction, drift compensation algorithms, and automatic dilution factor application. Data export supports CSV, XML, and PDF report formats—with configurable templates aligned with ISO 17025 reporting clauses. Raw spectral intensity values, flame temperature logs, and gas pressure timestamps are retained for full traceability.

FAQ
What flame gases are compatible with the FP6400A?
Air-propane and air-butane mixtures are supported; propane is recommended for optimal Na/K sensitivity and flame stability. Hydrogen or acetylene are not supported due to excessive thermal output and safety constraints.
Can the FP6400A be validated for regulated environments?
Yes—the instrument includes IQ/OQ documentation templates, and firmware supports 21 CFR Part 11-compliant user authentication, electronic signatures, and change-controlled audit trails.
Is external calibration verification required before each batch?
Per ISO/IEC 17025, a continuing calibration verification (CCV) standard must be analyzed every 10 samples or at start/end of run; the FP6400A software enforces this via configurable QC alert thresholds.
What maintenance intervals are recommended?
Nebulizer capillary cleaning every 8 hours of operation; burner head inspection and alignment every 200 hours; optical filter transmission verification annually using NIST-traceable reference standards.
Does the FP6400A support multi-element analysis beyond Na and K?
With optional filter modules (e.g., 422 nm for Ca, 535 nm for Ba), the FP6400A supports up to five elements sequentially; however, true simultaneous multi-element capability requires ICP-OES instrumentation.
