Vario PYRO Cube

CNSOH isotope ratio analysis

What is the vario PYRO Cube? 

The vario PYRO cube delivers highest precision and accuracy for OH and CNS isotope ratio analysis. This elemental analyzer for isotope ratio analysis (EA-IRMS) can be operated in OH mode (standard configuration) or CNS mode (optional), offering CNSOH analysis in a single instrument.

It provides reliable results for samples up to 1 g and pairs with high-performance IRMS systems to ensure outstanding ease of operation and durability.

Features of the PYRO Cube 

  • Precise oxygen isotope analysis: complete baseline separation of CO and N2 during δ18O measurements
  • Matrix-independent results: achieved through high-temperature pyrolysis up to 1,500 °C
  • All-in-isotope ratio analysis: perform OH and CNS analysis with a single instrument
  • High precision and accuracy: advanced gas separation and preconcentration ensure reliable results
  • Wide measurement range: suitable for samples from the low microgram range up to grams
  • Low maintenance: designed for extended uptime and minimal service needs

How does it deliver high precision in OH and CNS analysis? 

  • Advanced Purge and Trap (APT) Technology: ensures excellent peak shapes, full peak separation, and advanced gas preconcentration
  • Trace sulfur detection: even samples with very low sulfur content in high-carbon matrices can be accurately analyzed
  • Fast analysis: OH and CNS measurements completed in minutes

Precise oxygen isotope analysis 

  • Patented backflush system: eliminates N₂ interference in nitrogen-containing samples
  • Complete baseline separation: CO and N₂ are fully separated for δ18O analysis
  • Superior CO peak focusing: ensures reliable oxygen isotope measurements every time

How does it guarantee matrix-independent results? 

  • Operates at up to 1,500 °C with an extra-long furnace hot zone
  • Ensures full conversion of sample oxygen to carbon monoxide
  • High temperature guarantee matrix-independent measurements across diverse sample types

Easy operation and maintenance 

  • Autosampler with standard 120-position (optional 240), reloadable at any time for unattended 24/7 operation
  • Separated combustion and reduction tubes to extend tube lifetime and reduce maintenance
  • Big ash finger ensures long-term system uptime
  • User-friendly design: Tool-free clamp connections and slide-out furnace provide easy access and a comfortable working posture

Frequently asked questions

EA-IRMS tells you both the elemental composition and the isotopic signature of a sample.
  • EA (Elemental analysis) quantifies elements such as carbon (C), hydrogen (H), nitrogen (N), and sulfur (S), and oxygen (O) when a dedicated module is used. The sample is combusted or pyrolyzed, and the resulting gases are analyzed to determine the percentage of each element.
  • IRMS (Isotope Ratio Mass Spectrometry) measures the ratios of stable isotopes (e.g., ¹³C/¹²C, ¹⁵N/¹⁴N, ¹⁸O/¹⁶O). These isotopic signatures help determine a sample’s origin, authenticity, or the processes it has undergone.
It provides reliable results for samples up to 1 g and covers a wide measurement range from low micrograms up to grams.
Precise oxygen isotope analysis is achieved through complete baseline separation of CO and N₂ during δ¹⁸O measurements.
It operates at temperatures up to 1,500 °C with an extra‑long hot zone, ensuring full conversion of sample oxygen to carbon monoxide and guaranteeing matrix‑independent measurements.
It is an ideal solution for:
  • Environmental laboratories
  • Academic research groups
  • Quality control laboratories
  • Contract laboratories
It can analyze:
  • Chemicals
  • Soil and sediment
  • Plants
  • Food and beverage
