Pyrolytic Graphite Tube

Advantages of Pyrolytic graphite tube

Its shape is mostly hollow tubular, which has some having a platform structure, and its core advantages are prominent.

Extremely strong heat resistance stability

It is capable of withstanding temperatures ranging from 1800°C to 2500°C, which meets the strict temperature requirements for atomization of various metal elements.

High chemical inertness

It is unlikely to react with the elements to be measured in the sample or reagents during the atomization process. So it can significantly reduce detection interference.

Excellent thermal and electrical conductivity

Graphite tube can quickly and uniformly heat up, which ensures the sample is efficiently converted into free atoms, improving detection sensitivity.

High purity

Its carbon content typically exceeding 99.9% and it has a smooth inner wall, low adsorption capacity. So it can reduce sample residues and ensure the accuracy and repeatability of the detection results.

Good mechanical strength

Its structure is dense, and a single tube can be repeatedly used for tens of sample analyses. These make it extend the service life and reduce detection costs.

Strong adaptability

It can be customized in size according to different types of atomic absorption spectrometers to meet diverse detection needs.

Uses of Pyrolytic graphite tube

Spectral detection field

As the core component of the atomizer in an atomic absorption spectrometer

It can heat the target metals in the sample to the state of atomization, which enables precise detection. You can use it in the screening of heavy metals in food, the supervision of harmful metals in cosmetics, and clinical medical applications. And in the detection of heavy metal residues in pet food, it can also provide data support of safety.

Materials Science Field

In the high-temperature sintering experiments of new alloys

Due to its high-temperature resistance and low reactivity advantages, it assists in observing the optimization of microstructure and component composition.

As a high-temperature carrier

In the ceramic-metal coating bonding experiments, you can use it to help test the adhesion strength.

As an inner liner for the synthesis of nano-metal oxides

It can ensure the purity and uniformity of particle size of the materials, which facilitates material research.

The field of electronics industry

As the heating medium

In the high-temperature reliability testing of micro electronic components, it can simulate the working conditions of the actual components under extreme high-temperature environments. And then testing the performance stability to ensure the normal operation of the electronic components in harsh conditions.

Geology exploration and metallurgy field

For the detection of metal elements in rock and ore samples

It enables quantitative analysis of mineral resources, providing data support for exploration decisions. And It is also possible to analyze the metal recovery rates at each stage in the mineral processing to optimize the process.
