Introduction
A flame photometer, also known as a flame emission spectrometer, is an analytical instrument used to measure the concentration of certain elements, particularly alkali and alkaline earth metals, such as sodium, potassium, calcium, and lithium, in solutions, by measuring the light emitted when the sample is introduced into a flame, and it is used in clinical, agricultural, environmental, and food laboratories. In operation, the sample solution is aspirated and nebulized into a flame, typically an air-propane or air-acetylene flame, and the heat of the flame excites the atoms of the elements in the sample, which emit light at characteristic wavelengths; the emitted light is passed through a filter or monochromator that selects the wavelength for the element of interest, and the intensity of the light, measured by a photodetector, is proportional to the concentration of the element, and the concentration is determined by comparison with calibration standards, and the instrument is simple, rapid, and economical, and it is used with internal standards for higher accuracy. Flame photometers are used in clinical laboratories for measuring sodium and potassium in serum and urine, in agriculture for measuring potassium, calcium, and sodium in soil and plant samples, in the food industry for measuring sodium and potassium in foods, in water analysis, in the pharmaceutical industry, in cement and glass analysis, and for many other applications, and they are available as benchtop instruments with features such as multiple channels for different elements, digital displays, and automated dilution. With their simple and rapid measurement of alkali metals, flame photometers are essential instruments for elemental analysis.

FAQ
Q1: What testing scenarios is this photometer mainly applied to?
A: The flame photometer is used in clinical diagnostics, environmental monitoring, food and beverage, agriculture, industrial processing, petroleum and research to measure the concentration of alkali and alkaline earth metals (sodium, potassium, lithium, calcium, barium) in liquid samples by flame emission spectroscopy for clinical diagnosis, environmental monitoring and quality control. It supports clinical electrolyte measurement (serum/urine sodium, potassium, lithium), environmental water quality monitoring (sodium, potassium, calcium), food and beverage mineral analysis, agricultural soil and plant analysis, industrial process water monitoring, petroleum product analysis, and cement and glass analysis. Flame photometry provides a simple, cost-effective method for measuring select metals, widely used in clinical and industrial laboratories for routine analysis.
Q2: What standards does the photometer comply with?
A: The flame photometer follows relevant ISO, ASTM and GB/T standards for flame photometry, including ISO 9964 for sodium and potassium, ASTM D4192 for potassium, ASTM D4191 for sodium, and relevant clinical standards. The hardware complies with IEC 61010 laboratory safety standards. Calibration should use certified reference standards traceable to international standards. Clinical use follows applicable medical device regulations and laboratory accreditation requirements. Fuel gas (compressed air, propane/butane/natural gas) safety follows applicable regulations.
Q3: What is the warranty period for the whole machine and key components?
A: The whole flame photometer is covered by a 12-month warranty. The burner, nebulizer, optical system, detector, controller and housing are covered, while filters, burner parts, tubing and fuses are consumables or accessories. Damage from improper use, burner damage or unauthorized repair is excluded. Extended service contracts may be available.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with flame photometry, sample preparation and gas safety. We provide operation manuals, training and application support. Proper sample preparation, calibration, burner operation, gas safety, maintenance and result interpretation are important for accurate results and safe operation.

A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration with certified standards recommended before each analytical batch for clinical use. Burner and nebulizer cleaning per schedule. Optical filter condition checked. Gas flow and pressure verified. Full system performance verification annually. Routine maintenance of burner and nebulizer recommended.
Q7: Are supporting consumables universal?
A: Calibration standards, filters, burner parts, tubing and gas are available from laboratory suppliers, though instrument-specific parts should be verified. Long-term consumable cost depends on sample volume and gas usage.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes number of elements (single, dual, multi), detector type, filter configuration, sample capacity, automation level, data output and accessories. Additional filters, standards and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the flame photometer and accessories with an operation manual. On-site installation, calibration and training are not included for standard orders but can be arranged at additional cost. Remote guidance is provided. Proper gas supply and ventilation are required.
Q10: What types of samples are compatible with this equipment?
A: The flame photometer measures sodium, potassium, lithium, calcium and barium in aqueous solutions including clinical samples (serum, urine, diluted), environmental water, food digests, soil extracts, industrial water and other liquid samples within the concentration range and specification. Samples should be clear and free of particulates (filter if necessary). Different elements require specific optical filters and may have different concentration ranges. Users should follow the specific test method for sample preparation and dilution, calibrate with certified standards covering the sample concentration range, use proper gas supply (compressed air + fuel gas), maintain proper burner operation (stable flame), allow proper warm-up time, include quality control samples, report results in appropriate units (mmol/L for clinical, mg/L for environmental) with method specified, and for clinical use, follow applicable medical device and laboratory accreditation requirements. The burner should be cleaned regularly to prevent clogging. The nebulizer should be maintained per manufacturer schedule. Fuel gas cylinders should be properly secured and ventilated. The instrument should be operated in a well-ventilated area due to combustion products. For samples with high dissolved solids, proper dilution is required to prevent burner clogging. The flame should be inspected regularly for proper color and stability. Waste should be disposed of per applicable regulations. The instrument should be shut down properly (fuel gas first, then air) to prevent safety hazards.
