Overview
The NEXOPART e200 LS Air Jet Sieve Analyzer is a precision-engineered instrument designed for the reliable, reproducible dry sieving of fine and ultrafine powders—typically in the range of 20 µm to 4,000 µm—where conventional mechanical sieving fails due to particle agglomeration, electrostatic adhesion, or mesh blinding. Developed from the legacy air jet sieve technology of Hosokawa Alpine AG and now distributed under the NEXOPART brand (a strategic consolidation of Haver & Boecker’s screening expertise and Alpine’s particle characterization heritage), the e200 LS operates on the principle of controlled turbulent air dispersion within a sealed sieve chamber. A high-velocity, tangentially directed air jet—generated by a rotating nozzle mounted on a precisely balanced rotor—is ejected through a narrow slit (<0.5 mm width) at supersonic velocity across the surface of a standardized test sieve (ISO 3310-1 or ASTM E11 compliant). This dynamic airflow disrupts particle clusters via shear forces and inertial separation, while simultaneous vacuum aspiration (maintained by an integrated industrial-grade dust collector) continuously removes fines through the sieve mesh. The result is a gravimetrically resolved particle size distribution based on retained mass, with no liquid medium, no operator-dependent tapping, and minimal sample handling error.
Key Features
- Integrated vacuum-assisted air jet dispersion system with digitally controlled rotational speed (0–300 rpm) and programmable sieve dwell time (1–300 s)
- Automated negative-pressure calibration prior to each analysis cycle, ensuring consistent suction force and eliminating manual manometer adjustment
- Standardized sieve compatibility: accepts all ISO 3310-1 and ASTM E11 round sieves (75–400 mm diameter), including stainless steel and electroformed meshes down to 20 µm nominal aperture
- Robust aluminum alloy housing with IP54-rated electronics enclosure and vibration-damped base for laboratory stability
- Touchscreen HMI with intuitive workflow navigation, real-time pressure monitoring, and automatic end-of-test detection via differential pressure stabilization
- Compliance-ready architecture: supports 21 CFR Part 11 audit trails, electronic signatures, and user-access-level configuration (Admin / Operator / Viewer)
Sample Compatibility & Compliance
The e200 LS is validated for use with free-flowing, cohesive, and slightly hygroscopic dry powders—including pharmaceutical actives and excipients, mineral fillers, cement clinker, food-grade starches, toner pigments, and ceramic precursors. It excludes samples requiring wet dispersion, thermally unstable materials (>80 °C operating limit), or those generating hazardous dust beyond OSHA PEL thresholds without auxiliary containment. Regulatory alignment includes full traceability per GLP and GMP environments: all method parameters (sieve ID, rotation speed, duration, vacuum setpoint), operator ID, timestamp, and raw weight data are logged with immutable timestamps. Calibration certificates conform to ISO/IEC 17025 requirements when performed by accredited service partners.
Software & Data Management
The embedded firmware supports export of full analytical reports in PDF and CSV formats, including sieve-specific mass retention curves, cumulative undersize plots, and statistical summaries (D10, D50, D90, span). Optional PC-based software (NEXOPART AnalyzeSuite™) enables multi-instrument fleet management, SPC charting against historical baselines, and automated report generation compliant with internal QA templates or external regulatory submissions. All data storage adheres to ALCOA+ principles: attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available.
Applications
- Pharmaceutical QC labs: assay uniformity testing of micronized APIs per USP and EP 2.9.31
- Mineral processing R&D: classification efficiency evaluation of ground limestone, talc, or barite slurries after drying
- Food & nutraceutical manufacturing: verification of particle size consistency in powdered vitamins, cocoa, or whey protein isolates
- Advanced materials production: quality gate screening for battery cathode powders (e.g., NMC, LFP) prior to slurry mixing
- Cement and construction chemistry: fineness control of Portland cement per EN 196-6 and ASTM C204
- Toner and pigment development: batch-to-batch reproducibility assessment in electrostatic imaging applications
FAQ
What sieve standards does the e200 LS support?
It accepts all round test sieves conforming to ISO 3310-1, ASTM E11, and DIN 4188, including stainless steel woven wire, electroformed nickel, and sintered metal meshes.
Is method validation documentation available?
Yes—NEXOPART provides IQ/OQ protocols, a certified reference material (CRM) test kit (SiO₂ standard powder, NIST-traceable), and SOP templates aligned with ICH Q5A and USP general chapters.
Can the system be integrated into a LIMS environment?
Via optional RS-232/USB-to-Ethernet gateway and HL7-compliant API, enabling bidirectional data exchange with major laboratory information management systems.
What maintenance intervals are recommended?
Daily visual inspection of sieve gasket integrity; monthly cleaning of the rotary nozzle assembly and vacuum filter; annual recalibration of the load cell and pressure transducer by authorized service personnel.
Does the e200 LS require compressed air?
No—it operates solely on electrical power (230 V AC, 50/60 Hz) and generates its own air jet via the internal motor-driven nozzle; only the dust collector requires standard mains power.
