A handheld metal analyzer is a spectrometer based on XRF (X-Ray Fluorescence) spectral analysis technology, primarily consisting of a detector, CPU, and memory. Its portability and accuracy make it crucial in applications such as alloys, ores, environmental testing, and consumer goods.

Handheld spectrometers require high resolution and signal-to-noise ratio, superior intensity accuracy and wavelength accuracy, robust resistance to external interference, and excellent instrument stability. The software of the instrument should be capable of performing complex mathematical calculations such as derivatives and deconvolution, calculate spectral similarity, pattern recognition analysis, support multivariate calibration analysis, and allow for user-built spectral libraries and searches.
