Elementar vario EL cube - CHNS - He200014283

The vario EL cube CHNS (He200014283) is an elemental analyzer for simultaneous determination of carbon, hydrogen, nitrogen and sulfur in solids and liquids. It performs CHNS analyses across a wide range of sample sizes and element concentrations, and can be optionally upgraded for oxygen, chlorine and total inorganic carbon (TIC). The instrument is designed for high-precision, low-maintenance operation and unattended 24/7 use in laboratories analyzing pharmaceuticals, fuels, soils and other organic/inorganic matrices.

Key Features:

• Model: vario EL cube CHNS (Manufacturer part code He200014283)
• Weighing/sample size range: micro (<1 mg) up to 1.5 g (inorganic samples) and up to 20 mg organic matter
• Element concentration range: C up to 40 mg absolute; H up to 3 mg; N up to 15 mg; S up to 6 mg (O and Cl optional)
• Combustion unit temperature: complete digestion up to 1,200 °C (1,800 °C at combustion point with tin foil)
• Analysis time: approximately 3–4 minutes per element, self‑optimizing

Advantages:

• High analytical versatility and sensitivity, enabling simultaneous CHNS analysis from microgram-level samples to larger organic and inorganic samples
• Low‑maintenance design and automation optimized for unattended 24/7 operation, supporting high system uptime
• Blank‑free sample introduction and focused oxygen jet injection with high furnace temperature ensure complete combustion and reliable, matrix‑independent results
• Dedicated purge-and-trap chromatography with gas‑selective adsorption columns provides complete baseline separation of gases for precise quantification
