Designed as the successor of the most successful elemental analyzer, vario EL III, the vario EL cube is again the most versatile instrument in CHNS+O+Cl analysis.
Based on the "cube" platform it represents a thousand-fold proven method using latest manufacturing technology and intelligent engineering in the user interest. The established purge&trap chromatography guarantees baseline separation under all circumstances for all kinds of samples.
Thông số kỹ thuật
Largest weighing range
from micro (<1 mg) to macro (800 mg soil) sample weight, depending on requirenemtns up to 20 mg organic matter
Largest dynamic range of element concentrations and element ratio
up to 40 mg C abs. or 15 mg N abs. (or 100%), from ppm to 100%
Purge&trap Chromatography
Separation of gaseous components on up to three specific columns for perfect separation without overlap and automatic optimization of the analysis time
High temperature combustion unit
quantitative sample digestion at up to 1200 °C – with ten years furnace warranty (1800 °C at the point of combustion when tin foil is used). This is the prerequisite for 100% recovery also with samples difficult to combust. Jet injection of oxygen directly to the sample leads to highest oxygen concentrations at the point of combustion and low gas consumption
Multipoint calibration
stable over months and matrix independent
