Key Features

Elementrac ONH-p

  • Low gas consumption and high sensitivity due to closed gas system
  • Easy application of pins, powders and granules
  • Inexpensive argon as carrier gas possible
  • Short analysis time
  • Powerful impulse furnace with 8.5 kW
  • Optional Autocleaner
  • Reliable ON elemental analysis of inorganic samples like steel, non-ferrous metals, ceramics, slags, ores, etc.

Operation and Analysis Process

Step 1: Logging the sample into the ELEMENTS software

The sample ID is logged into the software and the weight is automatically transferred (see step 2).

Step 2: Weighing and introduction of sample into the port

The ELEMENTRAC OH-p 2 analyzes volumes from a few mg up to 2 grams safely and precisely. Rod-shaped or granular samples can be applied directly. For the elemental analysis of powders, a capsule is recommended which does not have to be sealed.

Step 3: Analysis

The empty graphite crucible is then placed on the lower electrode and the elemental analysis is started via the ELEMENTS software. The software controls all subsequent process steps.

Step 4: Data output and export

120 to 180 seconds after the analysis has started, the measured concentrations are available for export as a report or via LIMS.
