Mobile Spectrometers

Mobile spectrometers have its seeds in Belec history as the company founder was significantly involved in scientific processes and the invention of such instruments.

While the instruments „only“ served as detectors of material mix-up at the beginning, they are highly precise and fast analytical devices, today. Due to constant improvement and further development, there is nearly no difference compared to the stationary devices.

The Belec probe connector system allows a fast and easy handling of the especially at Belec developed probe types. There are three main probe types for different applications:

The air sparking probe was designed for quick mix-up checking of large material quantities. A sample preparation is not necessary in the most cases. Chemical compositions (except C-, P- and S-concentration) and the corresponding quality and/or material number are determined within less than three seconds. Here, the length of the optical fiber can be up to 10 m.

For working with the argon standard probe, an optical fiber length of 3m is recommended. A careful sample preparation grants an outstanding analysis accuracy inclusive C-concentration (without P and S). The measuring process takes about 15 seconds. As the sparking process takes place under argon atmosphere, there is a mounting device for a 10l-argon bottle at the transport trolley of the instrument.

To analyse also the elements phosphor and sulfur with the mobile spectrometer, the so-called argon special probe is required. As the measuring wavelengths of these elements are very low (P: 178,3 nm and S: 180,7 nm) they can’t be transferred with an UV optical fiber. Therefore, Belec developed a very small spectrometer, which is integrated in the sparking probe and optimized for low wavelengths. All other elements are measured over the optical fiber – as with the argon standard probe.
