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.
