Thermo Elemental 10046010 (AS2500) – Automated Liquid Sampling Module | Timberline IIL Platform
Engineering Background: The Thermo Elemental Timberline IIL is a dedicated continuous-flow hydride generation system engineered for ultra-trace determination of hydride-forming elements (As, Se, Sb, Bi, Pb, Sn, Te, Ge) in complex sample matrices. The AS2500 autosampler module (part number 10046010) provides fully automated, unattended liquid sample introduction, eliminating manual pipetting errors and dramatically improving throughput in high-volume analytical laboratories.
Product Positioning: This unit is a verified surplus / refurbished autosampler assembly sourced from decommissioned Thermo Elemental Timberline IIL installations. It is supplied with all referenced sub-assemblies: flow cell FL 18/6, manifold block G34924-M1011, reagent pump head H2-B2, and valve/tubing kit C2054-2113-75SLK. Ideal for laboratories maintaining legacy Timberline IIL systems or integrating into custom hydride generation workflows.

Proven Application Environments
- Environmental Monitoring: Trace arsenic and selenium in drinking water, wastewater, and soil digests per EPA 200.9 / ISO 11969.
- Food & Agriculture: Inorganic arsenic speciation in rice, seafood, and feed materials per EC 1881/2006 limits.
- Clinical & Toxicology: Urinary arsenic and blood selenium in occupational health screening.
- Geological & Mining: Multi-element hydride suite in ore digests and leachates.
- Pharmaceutical QC: Elemental impurity profiling per ICH Q3D guideline.
- Industrial Process: On-line or at-line monitoring of hydride-forming elements in process streams.
Engineering Advantages
- Unattended Batch Analysis: Automated sample/reagent introduction eliminates operator fatigue and pipetting variability across large sample queues.
- Optimized Flow Chemistry: FL 18/6 flow cell and G34924-M1011 manifold maintain precise reagent-to-sample ratios for reproducible hydride generation efficiency.
- Dual-Channel Peristaltic Pump (H2-B2): Independent control of sample and reductant (NaBH₄) flow rates; tubing replacement without system recalibration.
- Low Carryover Design: Rinse-station architecture and 75SLK tubing kit minimize cross-contamination between high- and low-concentration samples.
- Direct OEM Compatibility: Drop-in replacement for existing Timberline IIL installations; no firmware or interface modification required.
- Compact Footprint: Integrates on standard laboratory bench alongside Timberline IIL detector without additional support hardware.
System Architecture & Signal Flow
Sample is aspirated by the AS2500 peristaltic pump (H2-B2) and merged with acidified NaBH₄ reductant in the G34924-M1011 manifold. The resulting hydride gas is swept by an inert carrier (Ar or N₂) through the FL 18/6 flow cell positioned in the Timberline IIL optical path. The detector (AAS or AFS) records the transient absorbance/fluorescence signal, which is integrated by the system software. Waste liquid is directed to a phase separator and then to drain. The C2054-2113-75SLK valve/tubing kit controls sample/standard/blank switching and wash cycles.

Technical FAQ
Q: Is this unit compatible with the original Thermo Elemental Timberline IIL software?
A: Yes. The AS2500 communicates via the standard Timberline IIL interface; no driver modification is required.
Q: Can the FL 18/6 flow cell be replaced with a different path length?
A: The manifold block G34924-M1011 accepts standard Timberline IIL flow cells. Alternative path lengths (e.g., FL 10/6) can be fitted; contact us for compatibility confirmation.
Q: What reductant concentration is recommended?
A: Typically 0.5–2% NaBH₄ in 0.1% NaOH for most hydride-forming elements; optimum conditions depend on target element and matrix.
Q: Is export to my country permitted?
A: This instrument is classified under HS 9027.80.00 (analytical instruments) and is not subject to dual-use export controls. We ship worldwide with full export documentation.
Q: What warranty is provided?
A: 90-day functional warranty covering mechanical and electrical defects under normal laboratory use. Extended warranty available on request.
