Key features
- Exceptional mass dispersion – effective magnetic field radius of up to 60 cm for CO₂ allows for much higher mass resolution than standard.
- Zoom Optics technology – electronically adjustable converging lens that requires no moving parts, allowing simultaneous monitoring of mass ranging from 2–150 with precise peak matching.
- Flexible & highly customizable collector – standard collector for everyday stable isotope applications (C, N, O, S, H). Optional IS (clumped isotope) collector, optimized with a high-resolution narrow slit, mini-electrostatic filter (mini-ESA) for accurate analysis of low-intensity signals.
- Two variants to meet all needs – Perspective for stable isotope analysis C, N, O, S, H with top performance and reliability; Perspective IS (advanced) specialized for clumped isotopes with superior noise filtering and sensitivity.
- High resolution – Upgrade option for clumped isotope applications, maintaining high ion current with only 50% sensitivity loss. Standard Perspective achieves >200.
- Integration of various sample preparation devices – compatible with Nu Carb (carbonate analysis), Nu Sil (silicon analysis), gas chromatography (GC), elemental analyser (EA), dual inlet (DI) and continuous flow (CF).
Detailed description
Technology & principles
Perspective is an IRMS using a Nier ion source (8 kV), higher than conventional systems (5 kV). Ions are separated in a magnetic field and focused using Zoom Optics, overcoming the drawbacks of traditional "multi-purpose collector" design (peak slope, collecting foreign ions, spectral overlap), achieving high accuracy and stability.
Common limitations of IRMS:
- Fixed collector, difficult to adapt to diverse samples (carbonate, silica, gas, organic).
- Clumped isotopes require high resolution to separate noise, but conventional IRMS does not simultaneously meet sensitivity and resolution.
- Need flexibility to switch between Dual Inlet (high accuracy) and Continuous Flow (high throughput).
Advantages of the Perspective system:
- Two variants: Perspective (standard collector) and Perspective IS (narrow slot collector + mini-ESA) for clumped isotopes.
- Automatic isolation valve design on the source housing, easy to connect DI and CF.
Integration & expansion
Nu Sil: analysis of Si on small silica samples (a few µg), accuracy equivalent to MC-ICP-MS.
Nu Carb: automatic analysis of C, O in carbonate (samples <5μg), superior linearity and accuracy.
Compatible with GC, EA, dual inlet, CF.
