What are the main differences between a benchtop spectrometer and a handheld spectrometer

The penetration of precision excitation is better, and the stainless steel alloy is usually made by hand! Hand-held detection of aluminum is basically not possible, and it is necessary to rely on a desktop computer. With more problems can be a small window for me, spectrometer manufacturers.

Benchtop spectrometers are characterized by inconvenient movement, the need to operate in specific situations, and complex control. As a result, the skill level of manipulating employees is high. The rest of the benchtop spectrometer is the demand destruction analysis of the object being measured.

Commonly used workbench boundaries: forging, steel, metal receiving and smelting, as well as military, aerospace, natural gas, chemical, colleges and universities, commodity inspection, quality inspection and other units.

Handheld spectrometer features: Compared to the intuitive features of the desktop, it is small, lightweight, and easy to carry. In addition, handheld spectrometers can be used for on-site surveys without the need for a specific occupation situation like a desktop, perhaps with rapid and non-destructive effects without damaging the object being measured.

Although the measurements of the handheld spectrometer are relatively lower than those of the benchtop analytical structure.

Handheld General Limitations: Leakage, Petrochemical, Archaeology, Metal Processing, Pressure Vessel, Waste Receiving, Aerospace, Geological Exploration, Mine Surveying and Mapping, Excavation, Ore Sorting, Mining**, Metal Smelting, Situation Monitoring, Soil Monitoring, Toys, Fashion, Shoes and Hats, Electronics, etc.

First, you must first determine the material you need to detect, and locate the detection function of the handheld spectrometer. Landor is highly accurate, close to the level of laboratory-grade analysis, and provides a visual indication of the alloy grade and the percentage content of the elements (some elements can be displayed to three decimal places) and ppm content.

Second, look at the brand of handheld spectrometer, a big name like Landor is good, Landor Technology (Beijing) **** is the general distributor of Thermo Fisher Niton handheld spectrometer in the alloy geology and mining industry in China, and it is also the general distributor of Thermo Fisher ARL full-spectrum direct reading spectrometer in China.

Third, you can look at the configuration of the instrument, from the configuration of the instrument can also see how the performance of a handheld spectrometer, such as the optical tube, voltage, detector and other accessories in the spectrometer are important components of the handheld spectrometer, and the performance of most of the handheld spectrometer also depends on these main accessories. The whole analysis process can be completed in a few seconds, and the identification of alloy grades only takes 1 2 seconds, which is easy to operate, even for non-technical personnel.

Handheld spectrometers and portable spectrometers are not the same type of spectrometer. There are two types of portable spectrometers: handheld spectrometers and mobile spectrometers.

The former belongs to X-ray fluorescence spectrometers, and the latter belongs to optical emission spectrometers. Both can identify the grade of metal materials, and are widely used in pressure vessels, pipeline valve installation and on-site confirmation materials in petroleum, chemical, power plant, natural gas, gas and other industries, and are also used in scrap **, mixture inspection and screening, and raw material grade confirmation, especially suitable for stainless steel material grade confirmation and quantitative measurement of elements. However, the former cannot measure non-metallic elements such as c, s, and p, while the latter can measure non-metallic elements C, S, P, and even N in situ because it belongs to the spark direct reading spectrum and can be equipped with an additional ultraviolet chamber.

Most of the manufacturers of handheld spectrometers in portable spectrometers are monopolized by developed countries, such as Bruker in Germany, SPECTRO in Germany, Thermoelectric in the United States (its brand is Niton in the United States), Oxford in the United Kingdom, etc.

No, but the principle is the same, they are all qualitative by analyzing the spectrum of different elements, and quantitatively by analyzing the brightness, the difference is that one can be quantified through computer analysis; One is to judge through experience, semi-quantitative, that is, to estimate, and the result is directly related to human experience. There is also a big difference between hundreds of thousands and thousands.

It's different, the hand-held form is like a large ordinary digital multimeter, and the portable one is like a desktop oscilloscope.

None of them are right, handheld is portable, and spectrometers are only divided into two types: handheld, portable and desktop!

No, one is convenient and the other is not easy to carry.

Handheld spectrometers resemble pistols in that they can only detect metallic elements.

The mobile spectrometer (portable) looks similar to a small and medium-sized washing machine, and can be pushed on a stand (some have 4 wheels underneath), which is very convenient to go to the workshop, and can detect metal and non-metal elements.

The desktop spectrometer (cabinet type, vertical type) is similar to the medium and large freezer, fixed in the office, has strict requirements for temperature, humidity, etc., and the most comprehensive and accurate measurement.

Handheld spectrometer.

It is a spectral analysis instrument based on XRF (X-ray fluorescence, X-ray fluorescence) spectral analysis technology, mainly composed of X-ray tube, detector, CPU and memory, which is characterized by high resolution and signal-to-noise ratio, small shape, can quickly detect and analyze product attributes, and display it in numbers or trend charts, which is a very convenient instrumentation tool.

The application fields of handheld spectrometer mainly include: electric power, petrochemical, archaeology, metal processing, pressure vessels, waste materials, aerospace, geological exploration, mine surveying and mapping, mining, ore sorting, minerals, metal smelting, environmental monitoring, soil monitoring, toys, clothing, shoes and hats, electronic products and many other fields.

- On-site testing, fast and non-destructive, no need to send to the laboratory, greatly improving the efficient burial rate of the beam liquid.

The analysis is much faster than benchtop spectrometers, and the results can be displayed in just a few seconds.

Small size, light weight, easy to carry.

Handheld spectrometer is a spectral analysis instrument based on XRF (X ray fluorescence) spectral analysis technology, mainly composed of X-ray tube, detector, CPU and memory, because of its portability with high efficiency, portability, accuracy and other characteristics, so that it has important applications in alloys, ores, environment, consumer goods and other fields.

Handheld spectrometers require high resolution and signal-to-noise ratio, better intensity accuracy and wavelength accuracy, as well as strong anti-external interference and excellent instrument stability.
