Анализатор водорода ELEMENTRAC H-r

The ELEMENTRAC H-r uses the hot extraction method for the reliable and precise determination of hydrogen in small dimensioned metals based samples like steel or iron. For this purpose the ELEMENTRAC H-r utilizes a resistance heated quartz tube furnace which can be set up to maximum temperature of 1100 °C in combination with a powerful wide range TCD.

The ELEMENTRAC H-r is easy to use, requires only rudimental maintenance and is operated by the user-friendly ELTRA ELEMENTS software.

Преимущества оборудования

Resistance furnace with 13 mm inner diameter for analysis of medium and small sized samples
Suitable for analyzing steel samples for diffusible, residual, or total hydrogen
Maximum temperature of 1100 °C
Robust design allows use in both production control and laboratory environments
Easy calibration with standard materials or integrated gas dosing
Precise measurements even in the lower ppm concentration range

Примеры применения

сплавы, медь, сталь

Принцип работы

Operation of the ELEMENTRAC H-r is fast, safe and easy. After weighing of the sample on a connected balance the weight is transferred to the user friendly ELEMENTS software. Of course a manual application of the sample weight is also possible.

After the logging in, the sample can be placed in the cold zone of the furnace. After starting the analysis, the furnace is rotated upwards for the sample to fall into the hot zone where the sample releases its embedded hydrogen which is subsequently measured with the wide range thermal conductivity cell. Due to the application of selected temperatures also the measurement of different fractions (e.g. diffusible hydrogen) may be possible.

Depending on the applied sample mass and applied settings in the application the measurement requires 1 up to 15 minutes. After finishing of the analysis the released hydrogen amount is calculated by the software und the result could be exported as pdf, csv, txt file or via LIMS.

Calibration of the ELEMENTRAC H-r can be done via gas calibration, certified reference materials or primary substances like TiH₂.
