Oxygen / Hydrogen Analyzer ELEMENTRAC OH-p 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 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.
Oxygen / Hydrogen Analyzer ELEMENTRAC OH-p
The ELEMENTRAC OH-p is available as a single-element analyzer for oxygen or hydrogen only, or in a multi-element configuration for measuring OH. Whereas oxygen is determined as CO in up to two infrared cells, hydrogen is detected in its elemental form in a thermal conductivity cell.

Oxygen / Hydrogen Analyzer ELEMENTRAC OH-p Integrated standard solutions
The chemicals and filters required for the operation of the ELEMENTRAC OH-p elemental analyzer are arranged conveniently on the front panel and can be concealed behind a removable door during routine operation. This arrangement significantly reduces the time required for maintenance and increases user-friendliness. In addition, innovative details considerably improve the reproducibility of measurements.
Innovative sample port & pulsed chamber flushing
The new sample port of the OH-p elemental analyzer ensures comfortable operation and reproducible measured values. Differently shaped samples like solid pieces, granules or powder in capsules can be applied up to a weight of 2000 mg, and are quickly freed from the surrounding atmosphere with the help of pulsed carrier gas flushing in the sample port. Then they drop vertically into the preheated graphite crucible for analysis.
- Robust against dust development
- No closing of capsules required
- Direct application of up to 2000 mg granulate
- Low in maintenance and wear
Closed gas management
The ELEMENTRAC ONH elemental analyzer series uses a closed gas system in overpressure. This ensures that always 100% of the released sample gas is fed to the detectors which guarantees low detection limits and good reproducibility.
Oxygen / Hydrogen AnalyzerELEMENTRAC OH-p Options
In addition to the integrated solutions of the ELEMENTRAC OH-p elemental analyzer, further options are available to increase efficiency and extend the application range.
Autocleaner
By melting the sample in a graphite crucible at temperatures of up to 3000 °C deposits are generated at the upper electrode and in the furnace chamber which may affect the reproducibility of ONH measurements in a negative way. The new optional Autocleaner reliably removes these deposits, enabling precise elemental analysis even for high throughputs. Additionally, an efficient gas calibration and cleaning furnace for thorough carrier gas pre-cleaning are available for the elemental analyzer.
ELEMENTS Software
A central window (analysis and results) is the starting point from which all functionalities required for the daily routine are easily accessible. From here it is possible to group and export analyzed samples, or register and analyze new ones. The user may call up various subordinate functionalities like application settings, calibration, diagnosis, or status.
