PerkinElmer PinAAcle 900Z Atomic Absorption Spectrometer (Refurbished)

Overview

The PerkinElmer PinAAcle 900Z is a dual-mode atomic absorption spectrometer engineered for high-precision elemental quantification across diverse matrices — from environmental water and soil extracts to clinical serum, pharmaceutical excipients, and high-purity industrial chemicals. Unlike conventional AAS systems, the PinAAcle 900Z integrates flame atomization and graphite furnace electrothermal vaporization into a single compact optical platform using a patented stacked architecture. Its core measurement principle relies on Beer-Lambert absorption of resonant hollow cathode lamp (HCL) or electrodeless discharge lamp (EDL) radiation by ground-state free atoms generated in either the flame or graphite tube. The instrument employs longitudinal Zeeman-effect background correction — a physically robust method that eliminates spectral interferences without requiring separate deuterium lamp hardware or time-based correction cycles — ensuring accuracy in complex, high-salt, or organic-rich samples typical of clinical and regulatory laboratories.

Key Features

• Stacked dual-mode design: Flame and graphite furnace modules share a common optical path and detector, minimizing alignment drift and maximizing long-term reproducibility.
• Longitudinal Zeeman background correction: Real-time, wavelength-specific correction with no moving parts; validated per ASTM D1576 for trace metal analysis in fuels and ISO 8288 for nickel in ores.
• 8-position automated lamp turret with pre-warm functionality and usage logging: Ensures stable emission intensity and traceable lamp lifetime management per GLP requirements.
• AS900 graphite furnace autosampler: Integrated XYZ stage with programmable sample dilution, matrix modifier addition, and multi-step temperature ramping (up to 3000 °C).
• Optimized optical train: Fiber-coupled monochromator with 1800 grooves/mm grating and low-noise photomultiplier tube delivers sub-pg detection limits for Cd, Pb, and As in biological matrices.
• WinLab32 software suite: Fully compliant with FDA 21 CFR Part 11 — including electronic signatures, audit trail (user action, timestamp, parameter change), and secure method locking.

Sample Compatibility & Compliance

The PinAAcle 900Z supports aqueous solutions, digested solids (EPA Method 3050B/3052), organic solvents (with appropriate nebulizer and burner head), and viscous biological fluids via programmable furnace platforms. It meets performance criteria outlined in USP for elemental impurities in pharmaceuticals and CLIA-certified clinical assay protocols for Zn, Cu, Fe, and Mn in serum. All refurbished units undergo full factory-equivalent calibration verification against NIST-traceable standards (SRM 1643e, 1640a), and include documented IQ/OQ reports aligned with ISO/IEC 17025 laboratory accreditation expectations.

Software & Data Management

WinLab32 v3.5.2 provides complete instrument control, method development, and data reduction in a single interface. Raw absorbance/time and absorbance/wavelength data are stored in proprietary .WLB format with embedded metadata (lamp ID, slit width, integration time, furnace program). Export options include CSV, PDF analytical reports, and XML for LIMS integration. Audit trails record all user-initiated changes — including calibration curve reprocessing, integration window adjustment, and result flagging — with immutable timestamps and operator IDs. Data integrity is reinforced through role-based access control and encrypted local database storage.

Applications

• Environmental testing: Quantification of As, Se, Cd, and Pb in drinking water per EPA 200.9 and wastewater per ISO 11885.
• Clinical diagnostics: Trace element profiling (Ca, Mg, Zn, Cu) in whole blood and serum using certified reference materials (Seronorm™).
• Pharmaceutical quality control: Elemental impurity screening per ICH Q3D guidelines at ≤10% of PDE thresholds.
• Food safety: Ni, Cr, and Co analysis in infant formula and dietary supplements per AOAC 2013.02.
• Geological and metallurgical R&D: Multi-element analysis of ore leachates and alloy digests with matrix-matched calibration.

FAQ

Is this unit fully refurbished and tested to original OEM specifications?
Yes. Each PinAAcle 900Z undergoes comprehensive functional validation including wavelength accuracy (±0.1 nm), photometric linearity (R² ≥ 0.9999), and furnace temperature calibration (±15 °C across 100–2800 °C range), documented in a Certificate of Performance.
Does the system include compliance documentation for regulated labs?
Yes — delivered with IQ/OQ protocol templates, 21 CFR Part 11 configuration report, and NIST-traceable calibration certificate for lamp intensities and monochromator wavelength accuracy.
Can the AS900 autosampler be upgraded to support hydride generation?
No — the AS900 is optimized for graphite furnace use only. Hydride generation requires the optional FIAS-400 flow injection accessory, which is not included but available separately.
What is the expected lifetime of the graphite tubes under routine clinical use?
With proper pyrolysis and cleaning steps programmed in WinLab32, PerkinElmer Grade HGT tubes typically deliver 250–350 firings for biological matrices when operated within manufacturer-recommended temperature gradients.
Is remote software support available post-installation?
Yes — SpectraLab Scientific provides 12 months of complimentary remote diagnostics and method troubleshooting via TeamViewer-assisted sessions with certified AAS application specialists.
