Overview
The Aode Aode-200F Negative Pressure Air Jet Sieve Analyzer is an engineered solution for dry-powder particle size distribution analysis based on the standardized air jet sieving principle. It operates by generating a controlled, high-velocity negative-pressure airflow within a sealed sieving chamber, where a rotating slotted nozzle directs tangential air jets across the sieve surface. This induces both fluidization and dispersion of agglomerated particles through aerodynamic shear and impact against a transparent polycarbonate lid — effectively deagglomerating cohesive, electrostatic, or adhesive powders without mechanical vibration or rotor contact. The system complies with pharmacopeial requirements for air jet sieving methods, including Chinese Pharmacopoeia (ChP) 2020 Edition, Volume IV, General Chapter 0982 “Determination of Particle Size and Particle Size Distribution”. Its design prioritizes reproducibility, operator safety, and environmental containment — delivering ISO 13320-aligned dry-sieving performance for quality control laboratories in pharmaceuticals, chemicals, food, and advanced materials R&D.
Key Features
- Rotating 360° slotted nozzle with optimized air channel geometry to maximize particle dispersion efficiency and ensure uniform airflow distribution across the full sieve area
- Integrated pressure transducer with real-time vacuum monitoring and closed-loop pressure stabilization, maintaining consistent sieving dynamics throughout the test cycle
- 7-inch color TFT-LCD touchscreen interface supporting intuitive parameter setup: sieving time (0–999 s), vacuum setpoint (–2 to –8 kPa), and automatic result calculation
- Automatic calculation module providing immediate reporting of % retained (oversize), % passed (undersize), and cumulative mass distribution per sieve cut point
- Patented OPEN MESH function (optional) enables effective separation of near-mesh-size particles by dynamically modulating airflow pulsation and residence time
- High-efficiency sample recovery system achieving ≥99.9% collection rate via integrated cyclonic collector and static-dissipative polymer components
- Modular RS232 port for optional integration with analytical balances or LIMS; optional thermal printer for GLP-compliant hard-copy report generation
- Acoustically insulated housing with noise emission <65 dB(A) during operation, suitable for shared laboratory environments
Sample Compatibility & Compliance
The Aode-200F is validated for use with free-flowing and moderately cohesive dry powders, including microcrystalline cellulose (MCC), lactose monohydrate, APIs, catalysts, metal powders, and ceramic precursors. It meets the functional requirements of ChP 0982, ASTM E11-22 (Standard Specification for Woven Wire Test Sieve Cloth and Test Sieves), and ISO 2591-1:1988 (Methods of test for metallic powders — Part 1: Determination of particle size distribution by dry sieving). When paired with optional ultrasonic assistance, the effective lower detection limit extends to 5 µm — enabling extended-range characterization while retaining compliance with regulatory documentation standards such as FDA 21 CFR Part 11 (when used with validated software and audit trail configuration).
Software & Data Management
The embedded firmware supports traceable data handling with timestamped test records stored internally (up to 1,000 cycles). All parameters — including actual vacuum level, elapsed time, sample mass, and calculated distribution metrics — are logged with immutable metadata. Optional PC-based software provides CSV export, statistical trend analysis (e.g., X̄/R charts), and PDF report generation compliant with GLP/GMP documentation practices. Audit trail functionality, electronic signatures, and user-access levels can be implemented via third-party LIMS integration using standard RS232 protocols.
Applications
- Pharmaceutical QC: Granule and excipient particle sizing per USP , EP 2.9.31, and ChP 0982
- Materials science: Metal additive manufacturing powder qualification (e.g., Ti-6Al-4V, Inconel 718)
- Food industry: Starch, flour, and spice particle distribution verification
- Research labs: Method development for agglomerate-sensitive systems requiring non-destructive, low-energy dispersion
- Regulatory submissions: Generation of repeatable, instrument-qualified data packages for ANDA, NDA, or CMC sections
FAQ
What is the minimum particle size this instrument can resolve under standard operation?
The standard operating range begins at 20 µm. With the optional ultrasonic assist module, resolution down to 5 µm is achievable under validated conditions.
Does the instrument support multi-level sieving stacks?
No — the Aode-200F is configured for single-sieve-layer analysis per test cycle, consistent with air jet sieving methodology per ChP 0982 and ISO 2591-1.
How is calibration verified?
Calibration is performed using certified reference materials (e.g., NIST-traceable microcrystalline cellulose standards), with verification documented per internal SOPs aligned with ISO/IEC 17025 requirements.
Is the system compatible with GMP environments?
Yes — when equipped with optional audit trail software, electronic signatures, and validated printer output, it supports 21 CFR Part 11 compliance in regulated settings.
What maintenance is required for long-term accuracy?
Routine maintenance includes weekly cleaning of the nozzle assembly and sieve holder, quarterly verification of vacuum sensor linearity, and annual recalibration of the pressure transducer by authorized service personnel.
