Bruker Sequenom MassARRAY Genotyping System (Refurbished)

Overview

The Bruker Sequenom MassARRAY Genotyping System is a benchtop matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometer engineered for high-throughput, quantitative nucleic acid analysis in genomic research laboratories. Unlike continuous ionization techniques, MALDI employs pulsed laser irradiation to generate intact gas-phase ions from solid-phase samples co-crystallized with a UV-absorbing matrix—enabling soft ionization of large biomolecules such as oligonucleotides with minimal fragmentation. The system utilizes orthogonal acceleration TOF geometry combined with a dual-stage reflectron, where electrostatic ion mirrors double the effective flight path, significantly enhancing mass resolution and mass accuracy—critical for discriminating single-nucleotide polymorphisms (SNPs), methylation variants, and short insertion/deletion events. Designed specifically for multiplexed genotyping, the MassARRAY platform couples enzymatic primer extension or cleavage reactions with MALDI-TOF detection, delivering allele-specific mass signatures that are resolved at sub-Da mass accuracy.

Key Features

• Benchtop MALDI-TOF architecture optimized for nucleic acid applications—not general-purpose proteomics or small-molecule screening
• MassARRAY Analyzer 4 instrument with integrated laser optics, vacuum system, and high-sensitivity detector capable of resolving mass differences ≤0.1 Da in the 1,500–8,000 Da range
• Automated handling of up to two SpectroCHIP arrays per run—including both 96-well and 384-well formats—with robotic sample positioning and laser rastering
• Full turnkey configuration: includes dedicated workstation PC preloaded with TyperAnalyzer™ and MassARRAY® RT software, calibration standards, and consumables starter kit
• Refurbished and performance-validated by SpectraLab Scientific: all critical subsystems—including laser energy stability, vacuum integrity, ion optic alignment, and detector response—verified against original factory specifications
• 6-month comprehensive hardware warranty covering source, detector, vacuum pumps, and electronics; excludes consumables and user-induced damage

Sample Compatibility & Compliance

The MassARRAY system supports DNA and RNA samples prepared via proprietary iPLEX® or QC-PCR protocols, enabling robust detection of SNPs, copy number variations (CNVs), methylation status (via bisulfite conversion), and gene expression quantification (using RNase H2-dependent primer extension). Sample input requirements are low (≤10 ng genomic DNA per reaction), and multiplexing capacity reaches 40-plex per well on 384-well chips. All assays comply with CLIA- and CAP-aligned validation frameworks. While not FDA-cleared as an IVD device, the platform meets ISO/IEC 17025 requirements for testing laboratories and supports audit-ready documentation for GLP and GMP environments—including full electronic records, user access controls, and instrument usage logs compatible with 21 CFR Part 11 compliance when deployed with validated IT infrastructure.

Software & Data Management

Data acquisition and analysis are managed through the MassARRAY® RT Suite (v4.x or later), which provides real-time spectral visualization, automated peak detection, genotype calling with confidence scoring, and batch processing across hundreds of samples. TyperAnalyzer™ enables advanced clustering, QC metrics (e.g., signal-to-noise ratio, peak width, reproducibility across replicates), and export to LIMS-compatible CSV, Excel, or VCF formats. Raw spectra (.exp files) and processed results are stored with embedded metadata (operator ID, date/time, chip lot, assay protocol), supporting traceability and reanalysis. Audit trails record all software-initiated actions—including parameter changes, calibration events, and report generation—ensuring regulatory readiness for academic core facilities and contract research organizations.

Applications

• High-volume SNP genotyping in population genetics, pharmacogenomics, and biobank studies
• Targeted methylation profiling for epigenetic biomarker discovery and validation
• Allele-specific expression (ASE) analysis in heterozygous samples
• Low-frequency variant detection in oncology panels (e.g., hotspot mutations in BRAF, KRAS, EGFR)
• Quality control of CRISPR/Cas9 editing outcomes via fragment mass shift analysis
• Microbial strain typing using species-specific amplicon signatures

FAQ

Is this a factory-refurbished unit or dealer-refurbished?
This instrument has been fully refurbished and functionally validated by SpectraLab Scientific, an authorized Bruker service partner, following OEM-recommended procedures—including recalibration, laser energy optimization, and vacuum system leak testing.
What software licenses are included?
The system ships with perpetual, transferable licenses for MassARRAY RT v4.3 and TyperAnalyzer v4.1, including all current minor updates released prior to shipment.
Can the system be upgraded to support newer chip formats or assays?
Yes—the Analyzer 4 platform is compatible with all SpectroCHIP generations (including iPLEX Pro and Ultra), and firmware/software updates can be applied post-installation with technical support from SpectraLab.
Do you provide installation and training?
On-site installation, vacuum commissioning, and operator training (8 hours) are available as optional services; remote setup assistance is included at no additional cost.
Are spare parts and service contracts available after warranty expiration?
Yes—SpectraLab maintains a U.S.-based inventory of critical spares (laser diodes, detector assemblies, ion optics) and offers annual maintenance agreements with response SLAs and priority parts allocation.
