EURPING Acide3200 Automated Acid Counterflow Cleaner

Overview

The EURPING Acide3200 Automated Acid Counterflow Cleaner is an engineered solution for ultra-trace laboratory environments requiring stringent contamination control—particularly in inorganic elemental analysis workflows such as ICP-MS, ICP-OES, and HR-ICP-MS. It operates on the principle of controlled acid vapor phase cleaning combined with unidirectional counterflow rinsing and inert thermal drying. Unlike conventional acid baths or open-vessel steamers, the Acide3200 employs a closed-loop, gradient-sloped chamber architecture where sub-boiling HNO₃ or HCl vapors ascend uniformly across vertically oriented labware, followed by high-flow ultrapure water injection from both top and sidewall nozzles (50 total), ensuring complete removal of volatile acid residues and non-volatile metallic contaminants. The system’s design eliminates manual handling, minimizes operator exposure to corrosive vapors, and maintains internal cleanliness at ppt-level residual metal thresholds—validated via blank testing per ASTM D511 and ISO 17025-compliant verification protocols.

Key Features

• Fully automated end-to-end cycle: sub-boiling acid vapor generation → ultrapure water rinse → forced-air drying — all executed without human intervention.
• Chemically inert construction: entire wetted path—including chamber walls, spray manifolds, and condensate return lines—fabricated from high-purity PTFE, PFA, and TFM fluoropolymers to prevent leaching and adsorption.
• Modular acid management: external acid reservoir isolates storage from processing zone; acid recirculation is strictly unidirectional to eliminate cross-contamination between cycles.
• Real-time process monitoring: integrated pH sensor in waste line, temperature/pressure transducers in chamber, and conductometric feedback for rinse endpoint detection.
• EP-series exhaust neutralization system: electrochemical scrubber with replaceable reagent cartridges achieves >99.5% HNO₃/HCl capture efficiency at flow rates up to 120 m³/h, enabling benchtop deployment without fume hood dependency.
• Micro-negative pressure architecture: active ventilation initiates at power-on, maintaining −15 to −25 Pa differential between chamber interior and ambient lab environment—verified per EN 14175-3.
• Secure operational governance: three-tier password protection (operator / supervisor / administrator), audit trail logging compliant with FDA 21 CFR Part 11 requirements, and encrypted program storage.

Sample Compatibility & Compliance

The Acide3200 accommodates a broad range of analytical consumables and components, including borosilicate glass vials (e.g., SCOTT, Kimble), fused quartz tubes, PFA/TFM digestion vessels (up to 100 mL capacity), quartz torch injectors, Ni and Pt sampler cones, and sapphire lenses. All cleaning protocols are developed and validated against ISO/IEC 17025:2017 clause 7.2.2 (method validation) and align with USP Total Organic Carbon and EPA Method 200.8 trace metal recovery criteria. Residue testing confirms ≤0.1 pg/mL Cr, Fe, Ni, Cu, Zn, and Pb in post-clean blanks—meeting ICH Q5D and GLP traceability standards for method transfer documentation.

Software & Data Management

Control firmware runs on a deterministic real-time OS with dual-core ARM Cortex-A9 processor. The 9-inch capacitive touchscreen interface supports multilingual operation (English, German, Japanese, simplified Chinese) and provides graphical visualization of temperature ramp profiles, rinse conductivity decay curves, and exhaust scrubber saturation status. All cycle logs—including start/stop timestamps, parameter deviations, alarm events, and user authentication IDs—are stored locally on industrial-grade eMMC (16 GB) with optional Ethernet/Wi-Fi export to LIMS or ELN platforms. Data integrity safeguards include SHA-256 hashing of log files and write-once archival mode for regulatory submissions.

Applications

• Preparation of sample introduction hardware for high-sensitivity ICP-MS analysis (e.g., nebulizers, spray chambers, cones).
• Cleaning of calibration standards containers and volumetric flasks used in sub-ng/g quantitation.
• Decontamination of quartz and fluoropolymer components exposed to HF-based digestions.
• Reconditioning of reusable PFA vials in environmental monitoring labs performing EPA 6020B workflows.
• Supporting ISO 15195-accredited reference material producers requiring documented cleaning validation records.

FAQ

What acid types are compatible with the Acide3200?
Concentrated nitric acid (69–70%), hydrochloric acid (37%), and mixtures thereof (e.g., aqua regia) are supported. Hydrofluoric acid is not recommended due to material compatibility constraints.
Can the Acide3200 be integrated into a central ultrapure water system?
Yes—via optional 3/8″ push-fit inlet with pressure regulator (0.2–0.6 MPa); system includes flow sensor and auto-shutoff on low-pressure detection.
Is routine maintenance required for the EP exhaust scrubber?
Cartridge replacement is scheduled every 12 months under typical usage (≤5 cycles/day); saturation indicators appear on screen 72 hours prior to expiry.
Does the instrument support remote diagnostics?
Field-service engineers may initiate secure TLS-encrypted remote sessions via built-in cellular modem (optional) or LAN port, subject to customer-configured firewall rules.
How is compliance with ISO 17025 method validation addressed?
EURPING provides a Validation Support Package including IQ/OQ documentation templates, blank test protocols, and uncertainty budget worksheets aligned with EURACHEM/CITAC Guide CG4.
