Elemental Analysis — Proanalytica

Organic microanalysis

UNICUBE

UNICUBE – an elemental analyser that combines the low operating costs and high sensitivity of a micro elemental analyser with the dynamic measuring range of a macro analyser. UNICUBE is designed for simultaneous C, H, N and S analysis in solid and liquid samples, ranging from 0.1 mg of a chemical substance to 15 mg of liquid fuel to 1 g of inhomogeneous soil. In addition, the analyser offers options for oxygen and chlorine determination. The integrated autosampler, which can be refilled during analysis, is available with 60, 80, 120 or 240 positions for solid and liquid samples in capsules, or with 50 positions for liquid samples.

Organic macroanalysis

Vario MACRO cube

Vario MACRO cube CHNS – a universal analyser designed for macro-sized samples. Applications range from solid substances such as petroleum coke, lignite, bituminous coal or soil, to viscous and liquid samples such as tar or fossil fuels of all kinds. It offers the greatest versatility in macro elemental analysis, with simultaneous CHNS, CHN, CNS or CN determination from a single macro-sized sample. Sample preparation is kept to a minimum thanks to large sample weights of up to 1.5 g. High analysis speed thanks to the integrated autosampler with up to 120 positions, and low instrument maintenance requirements.

TOC analysis

Vario TOC cube

Vario TOC cube is a flexible TOC/TNb analyser for liquid and solid samples, with a measuring range from low ppb concentrations up to percent level. It determines TOC, NPOC, TC, TIC, DOC, POC and optionally TNb, using high-temperature catalytic combustion up to 1,200 °C and IR detection of CO₂. Autosamplers are available for up to 80 liquid samples, as well as for 80 or 120 solid samples, enabling fully automated operation and 24/7 analysis. SALTTRAP technology ensures reliable analysis of samples with high salt content while reducing maintenance requirements. Vario TOC cube offers a wide range of configurations to suit every application.

Nitrogen/protein analysis

Rapid N exceed PLUS

Rapid N exceed PLUS is a compact analyser for fast and reliable nitrogen and protein determination by the Dumas method, with an analysis time of only 3–4 minutes per sample. It handles solid and liquid samples with a weight/volume of up to 1.5 g / 1.5 mL, with a nitrogen measuring range from ppm level up to 100%. The integrated autosampler has 60 positions, with optional 80- or 120-position versions, and can be refilled during analysis. The instrument uses CO₂ as carrier gas, TCD detection and high-temperature combustion up to 1,200 °C, delivering low operating costs, high precision and simple routine operation.

Adsorbable organic halogen analysis

Xplorer

Xplorer is an automated analyser for fast and precise determination of organic halogens (AOX, TOX, EOX and POX) by thermal decomposition and microcoulometric detection in a wide range of liquid and solid samples. Interchangeable modules allow easy adaptation to different types of analysis, while a unique automatic sample introduction and ejection system ensures high throughput and reliable round-the-clock operation. The system complies with numerous international standards, including ISO, DIN, EPA, EN and NEN methods, and the intuitive TEIS software makes analysis control simple. It is suitable for drinking water, surface and ground water, waste and process water, soil, sediment, sludge, waste oils and pulp and paper industry products.

Automated chemical analysis

CFA analysers

Automated chemical analysers deliver faster, more economical and reliable analysis with consistently high-quality results, offering up to five times the capacity of chromatographic methods, lower chemical consumption and minimal waste. By integrating key sample preparation steps such as dilution, mixing, incubation, dialysis, distillation, UV digestion and hydrolysis, they significantly reduce analysis time and manual work. CFA analysers use Macroflow or Microflow segmented-flow technology and can be equipped with autosamplers of 52/104 or up to 240 (300) positions, multichannel dosing pumps and individual method manifolds, with automated system control and data processing via CFM software.

Mercury analyser

DMA-80 evo

DMA-80 evo is a direct mercury analyser for determining Hg in solid, liquid and gaseous samples without prior sample preparation, with an analysis time of approximately 6 minutes. Its advanced optical system delivers high sensitivity and repeatability across a wide measuring range, from ppt to ppm level, while a single long-lasting calibration can be used for different sample types. An automatic blank function reduces memory effects, and simple maintenance with minimal reagent consumption keeps operating costs low. The system complies with standard methods including US EPA 7473, ASTM D6722 and ASTM D7623, and is suited to environmental, food, agricultural, petrochemical, mining and cosmetics applications.
