Overview
The CETAC ASX-112FR-NEPTUNE Plus Autosampler Accessory Kit is a precision-engineered sample introduction system designed exclusively for integration with Thermo Fisher Scientific’s NEPTUNE Plus multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS). This accessory kit comprises PFA or FEP vials and capillary tubing optimized to maintain ultra-trace elemental integrity, minimize memory effects, and ensure compatibility with high-sensitivity isotopic ratio measurements. Unlike generic autosampler consumables, the ASX-112FR configuration adheres to the mechanical and fluidic interface specifications of the CETAC ASX-112FR platform—ensuring repeatable syringe-driven aspiration, precise dwell-time control, and seamless synchronization with the NEPTUNE Plus acquisition cycle. The system operates on low-flow, high-efficiency nebulization principles, supporting both aqueous and diluted acid matrix applications typical in geochronology, nuclear forensics, and stable isotope geochemistry laboratories.
Key Features
- PFA or FEP construction—chemically inert, ultra-low blank, and resistant to HF, HNO₃, and HCl at elevated concentrations (up to 12 M)
- Vial volume options: standardized 10 mL and 35 mL configurations; custom volumes available upon engineering review for specialized throughput or dilution protocols
- Dimensionally compliant with CETAC ASX-112FR robotic arm kinematics and tray indexing—no firmware modification required
- Integrated O-ring–sealed caps with PTFE-faced septa to prevent evaporation and atmospheric contamination during extended sequence runs
- Trace-metal-clean manufacturing environment (Class 100 cleanroom), certified per ISO 14644-1, with batch-specific certificate of analysis (CoA) including ICP-MS blank data for Be, Mg, Ca, Fe, U, and Pb
Sample Compatibility & Compliance
This accessory kit supports sample matrices commonly used in high-precision isotope ratio analysis, including nitric acid–digested rock leachates, ion-exchange purified element fractions, and synthetic standard solutions (e.g., NIST SRM 981, 982, 984 series). All components comply with ASTM D5673–22 (Standard Practice for Determination of Trace Elements in Water by MC-ICP-MS) and are compatible with ISO/IEC 17025-accredited laboratory workflows. The PFA/FEP materials meet USP Class VI biocompatibility requirements and are suitable for GLP-compliant method validation. No leachable fluorides or organics are detected above detection limits (<0.1 ng/g) when analyzed per EPA Method 200.8 revision 5.1.
Software & Data Management
The ASX-112FR-NEPTUNE Plus accessory does not require standalone software but fully interoperates with Thermo Fisher’s Neptune Plus Instrument Control Software (v3.4+) and IsoplotR-compatible acquisition templates. Sample metadata—including vial position, rinse time, uptake rate, and wash cycle count—is embedded directly into the .raw file header and exportable via Thermo’s Qtegra ISDS API. Audit trails for vial lot usage, calibration bracketing intervals, and carryover monitoring are retained within the instrument’s native database and support 21 CFR Part 11–compliant electronic signatures when deployed with validated LIMS integration (e.g., LabWare LIMS or STARLIMS).
Applications
- High-precision U–Pb, Lu–Hf, and Sm–Nd geochronology requiring sub-permil external reproducibility
- Nuclear safeguards analysis of uranium and plutonium isotopic signatures (e.g., ²³⁴U/²³⁸U, ²⁴⁰Pu/²³⁹Pu)
- Bioinorganic trace metal speciation studies involving Zn, Cu, Fe isotopes in serum or cell lysate digests
- Environmental tracer investigations using Sr, Nd, and Hf isotopes in seawater, riverine sediments, and volcanic glass
- Reference material certification projects aligned with IRMM, NIST, or JNIRS interlaboratory comparison protocols
FAQ
Is this accessory compatible with older NEPTUNE models (e.g., NEPTUNE Classic)?
No—mechanical and communication protocols differ significantly between NEPTUNE Classic and NEPTUNE Plus. Only ASX-112FR-NEPTUNE Plus–certified parts guarantee full robotic arm recognition and timed valve actuation.
Can I use non-PFA vials (e.g., borosilicate glass) with this system?
Not recommended. Glass introduces measurable Si, B, and Na blanks and exhibits poor acid resistance under hot HNO₃/HF conditions required for silicate dissolution. PFA/FEP is mandatory for sub-pg/g detection limits.
Does the kit include installation documentation or protocol SOPs?
Yes—each shipment includes a bilingual (English/Chinese) Technical Integration Guide covering mechanical alignment, leak testing, baseline stability verification, and troubleshooting common pressure fluctuation scenarios.
Are replacement vials supplied with lot-specific blank certificates?
Yes—every production lot undergoes ICP-MS blank screening across 28 elements; CoAs are digitally signed and accessible via QR code on the packaging label.
What is the maximum recommended operating temperature for the PFA tubing during heated spray chamber operation?
PFA maintains structural integrity up to 260 °C; however, for optimal aerosol transport efficiency and minimal thermal degradation, continuous operation above 120 °C is not advised without prior flow-rate recalibration and memory-effect validation.
