X-Ray Fluorescence Spectrometer CIT-3000SYB for RoHS & Halogen Compliance Testing

Overview

The CIT-3000SYB Energy Dispersive X-Ray Fluorescence (ED-XRF) Spectrometer is an industrial-grade benchtop analyzer engineered for regulatory compliance screening of restricted substances in electronic and electrical equipment. It operates on the fundamental principle of energy-dispersive X-ray fluorescence: a high-energy X-ray beam excites atoms in the sample, causing emission of characteristic secondary X-rays whose energies are uniquely tied to elemental identity, while intensities correlate quantitatively with concentration. Designed explicitly to meet the analytical requirements of Directive 2011/65/EU (RoHS 2), Directive 2002/96/EC (WEEE), and IEC 61249-2-21 (halogen-free material specifications), the CIT-3000SYB delivers trace-level detection of Pb, Hg, Cd, Cr(VI), Br, Cl, and other regulated elements across solid, powdered, and liquid matrices — without destructive digestion or chemical reagents.

Key Features

• Digital pulse processing architecture with 2048-channel multi-channel analyzer (MCA), enabling high-count-rate throughput without spectral pile-up or dead-time loss.
• Cryogenically cooled Si(PIN) semiconductor detector with energy resolution <150 eV at Mn Kα (5.9 keV), ensuring robust peak separation for overlapping L-lines (e.g., Pb Mα vs. As Kα) and accurate deconvolution in complex spectra.
• 40 kV microfocus tungsten-target X-ray tube with continuously adjustable voltage (0–40 kV) and current (0–100 µA), optimized for excitation efficiency across light (Na–Cl) and heavy (Pb–U) elements.
• Vacuum-compatible sample chamber (Ø140 mm × 50 mm height) facilitating low-Z element analysis (down to sodium) by minimizing air absorption of soft X-rays.
• Integrated hardware stabilization: precision high-voltage generator, temperature-compensated detector bias circuitry, and active thermal management ensure long-term signal reproducibility (RSD <2% over 8 h).
• Pre-configured RoHS calibration using NIST-traceable certified reference materials compliant with EN 62321-5:2013 and IEC 62321-7-2:2017 protocols.

Sample Compatibility & Compliance

The CIT-3000SYB accommodates heterogeneous industrial samples — including printed circuit boards (PCBs), plastic housings, metal alloys, solder pastes, and polymer pellets — in their native solid, pressed-powder, or liquid forms. Minimal sample preparation is required: flat-surface solids are measured directly; powders are homogenized and pelletized using the included hydraulic press and die set; liquids are sealed in X-ray transparent films. All measurement routines adhere to internationally recognized test standards: EN 62321-3-1 (screening of Pb, Hg, Cd, Cr, Br), EN 62321-3-2 (Cl and Br in polymers), and ASTM E1621 (standard guide for ED-XRF analysis). The system supports full audit trails and user-access logs required under GLP and ISO/IEC 17025:2017 laboratory accreditation frameworks.

Software & Data Management

The proprietary analytical software provides quantitative analysis via fundamental parameter (FP) and empirical calibration methods. It includes spectral deconvolution algorithms with background subtraction, peak fitting (Gaussian + tail modeling), and matrix correction for inter-element effects (e.g., Zr enhancement of Pb signal). Data export complies with ASTM E1341 and ISO 12849 formats. All instrument parameters, calibration files, measurement reports, and raw spectra are timestamped and stored in encrypted local databases. Software supports 21 CFR Part 11-compliant electronic signatures, role-based access control (admin/operator/auditor), and automated report generation in PDF/CSV/XLSX formats — suitable for internal QA documentation and third-party certification submissions.

Applications

• Routine screening of incoming components against RoHS Annex II substance limits prior to PCB assembly.
• Verification of halogen-free status (Cl + Br <900 ppm total, Cl <900 ppm, Br <900 ppm) in flame-retardant plastics per JIG-TPS-001 and IPC-4101D.
• Quantitative verification of plating thickness and composition in connector terminals and lead frames.
• Failure analysis of non-conforming lots through comparative spectral mapping and elemental distribution profiling.
• Support for supplier qualification programs requiring documented conformance to IECQ QC 080000 and IPC-1752A material declarations.

FAQ

Does the CIT-3000SYB require helium purging or vacuum for chlorine detection?
No — the integrated vacuum chamber eliminates atmospheric absorption of Cl Kα (2.62 keV), enabling reliable sub-20 ppm detection without external gas supply.
Can the system quantify chromium(VI) specifically?
ED-XRF measures total Cr content only. Speciation of Cr(VI) requires complementary techniques such as ion chromatography coupled with ICP-MS per EN 62321-7-1.
Is method validation support provided for ISO/IEC 17025 accreditation?
Yes — the manufacturer supplies documented uncertainty budgets, linearity studies, limit-of-detection verification reports, and standard operating procedures aligned with ISO/IEC 17025 Clause 7.2.
What maintenance intervals are recommended for the X-ray tube and detector?
The tungsten-target tube has a rated lifetime of ≥10,000 hours; the Si(PIN) detector requires no periodic replacement but benefits from annual performance verification using check sources.
Is remote diagnostics and software update capability available?
Yes — optional secure VPN-enabled remote support allows firmware updates, spectral library upgrades, and real-time troubleshooting by certified application engineers.
