Spray particle size analyzer

Introduction

A spray particle size analyzer is a specialized instrument used to measure the size distribution of droplets in sprays, aerosols, and atomized liquids, and it is used for characterizing spray nozzles, for quality control in spray applications, and for research in industries such as agriculture, pharmaceuticals, combustion, and manufacturing. The instrument measures the droplet sizes using laser-based techniques, most commonly laser diffraction, in which a laser beam passes through the spray and the light scattered by the droplets is detected and analyzed to determine the droplet size distribution over a wide range, and phase Doppler anemometry, which measures both the size and velocity of individual droplets by analyzing the interference pattern of scattered light; the instruments provide real-time, non-intrusive measurements of the spray without disturbing the flow. Spray particle size analyzers are used for characterizing and optimizing spray nozzles for agricultural spraying, for which the droplet size affects spray coverage, drift, and efficacy; for characterizing fuel injectors and combustion sprays; for pharmaceutical inhalation products, such as nasal sprays and inhalers, for which the droplet size affects drug delivery; for spray drying processes; for coating and painting sprays; for fire suppression; and for many other applications, and they are available as laboratory instruments and portable systems for field use, with features such as real-time measurement, wide size ranges, and data analysis software. With their ability to measure spray droplets, spray particle size analyzers are essential instruments for spray characterization and quality control.

FAQ

Q1: What testing scenarios is this analyzer mainly applied to?

A: The spray particle size analyzer is used in pharmaceutical development (inhalers, nasal sprays), agricultural spraying, automotive coating, cosmetic aerosol, industrial spraying and research to measure the droplet size distribution of sprays and aerosols for product development, quality control and performance optimization. It supports pharmaceutical inhaler and nasal spray droplet size testing per regulatory requirements, agricultural spray nozzle characterization for pesticide application, automotive paint and coating spray analysis, cosmetic aerosol product development, industrial spray nozzle performance testing, and research on spray dynamics. The spray particle size is a critical parameter affecting spray coverage, penetration, deposition and product performance. It is essential for pharmaceutical, agricultural, automotive, cosmetic and industrial applications requiring spray droplet size measurement for product development, quality control, performance optimization and regulatory compliance, where spray droplet size distribution is a critical parameter affecting spray coverage, penetration, deposition, efficacy and product performance in pharmaceutical inhalers, agricultural spraying, automotive coatings, cosmetic aerosols and industrial spray applications requiring precise, reproducible spray characterization using laser diffraction or imaging techniques.

Q2: What standards does the analyzer comply with?

A: The spray particle size analyzer follows ISO 13320 for laser diffraction particle size analysis, ASTM standards for spray characterization, and relevant GB/T standards. Pharmaceutical inhaler testing follows USP, EP and FDA guidelines for nasal and oral spray characterization (e.g., USP <1601>, FDA guidance). The hardware complies with IEC 61010 laboratory safety standards. Calibration should use certified particle size standards traceable to international standards.

Q3: What is the warranty period for the whole machine and key components?

A: The whole spray particle size analyzer is covered by a 12-month warranty. The laser/optical system, detector, spray chamber, controller and software are covered, while calibration standards, nozzles and fuses are consumables or accessories. Damage from improper use, contamination or unauthorized repair is excluded. Extended service contracts are available for this specialized instrument.

Q4: Is this device difficult to operate? Is professional training required?

A: Operation requires trained personnel familiar with spray characterization, particle size measurement and instrument operation. We provide comprehensive training, operation manuals and application support. Proper spray setup, measurement technique, calibration, data interpretation and safety procedures (particularly for pharmaceutical and chemical sprays) are important for accurate spray particle size analysis.

Q5: What is the typical lead-time for order delivery?

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 particle size standards recommended every 6-12 months. Laser alignment and optical system verification periodically. Spray chamber and optics cleaned per manufacturer schedule. Software updates installed as available. Full system performance verification annually. Routine verification with a standard spray for quality control use.

Q7: Are supporting consumables universal?

A: Calibration standards, nozzles, tubing and filters are available from specialized suppliers, though instrument-specific parts should be verified. Long-term consumable cost is moderate depending on usage and spray type.

Q8: Can I customize parameters or supporting accessories?

A: Customization includes measurement technique (laser diffraction, imaging), particle size range, spray chamber design, nozzle compatibility, software features and automation. Additional accessories and calibration standards can be ordered separately. Custom orders extend delivery lead-time.

Q9: Does the purchase include on-site installation and commissioning service?

A: Yes, spray particle size analyzers include on-site installation, commissioning, calibration and operator training by certified application specialists. Site preparation guidance is provided before delivery to ensure ventilation, environmental and space requirements are met.

Q10: What types of sprays are compatible with this equipment?

A: The spray particle size analyzer measures droplet size distribution of sprays and aerosols from nozzles, inhalers, spray bottles and other spray devices within the particle size range, spray rate and chamber specification. Different spray types (liquid, aerosol, pressurized) may require specific setup and accessories. Highly volatile or hazardous sprays require proper ventilation and safety measures. Users should select appropriate measurement technique for the spray type, calibrate with certified standards, follow proper spray setup and measurement technique per the standard method, ensure proper ventilation for hazardous or volatile sprays, report results as Dv10, Dv50, Dv90 and span with the test method specified, and for pharmaceutical use, follow applicable regulatory guidelines for inhaler and spray characterization. The spray chamber should be cleaned regularly to prevent residue buildup that can affect measurements. For pressurized aerosols, proper safety precautions including pressure relief and ventilation should be followed.
