I. Product Introduction

The XRF-Met1 gold purity analyzer is a precision instrument dedicated to the gold recycling industry. Equipped with a new-generation Si-PIN detector, it performs fast, non-destructive and accurate qualitative and quantitative analysis of the purity and composition of gold and its alloys, so that recyclers avoid losses caused by misjudgement and improve both efficiency and profitability. The user-friendly interface simplifies the testing workflow and allows even beginners to operate the instrument quickly, while the high-precision results provide a transparent basis for both buyers and sellers.

II. Product Features

1Calibration-free designthe instrument is precisely calibrated and its core parameters are fixed before delivery, so no repeated calibration with silver-copper alloy reference pieces is required in daily use. It is ready to work out of the box, saving considerable time and effort.
2Multi-layer safety protection with intelligent warninga four-dimensional active safety system covering sound, light, electricity and physical isolation. A yellow warning lamp lights up whenever the high voltage is on; the high-voltage supply is cut within milliseconds if the chamber lid is opened; a fully metal-enclosed cabinet with multi-layer radiation shielding keeps X-ray leakage extremely low; and the software blocks a test start and raises an alarm if the lid is not fully closed.
3Non-destructive testingbased on X-ray fluorescence, the measurement excites characteristic fluorescence from the atoms of the sample and leaves the sample completely unchanged, which is essential for precious jewellery, cultural relics and alloy samples.
4Simultaneous multi-element analysisqualitative and quantitative analysis of up to 72 elements including Au, Ag, Cu, Zn, Ni, In, Co, Pd, Pt, Re, W, Cd, Rh, Fe, Pb, Sn, Mn, Cr, Ru and Os, with more than 21 elements routinely measurable.
5Ultra-high precisionthe instrument clearly resolves the approximately 0.09% purity difference between 99.99% (four-nine) and 99.9% (three-nine) gold, meeting the requirements of precious metal trading and inspection bodies.
6Rhenium and tungsten alarmbuilt-in intelligent recognition catches the characteristic signals of rhenium and tungsten, the most common adulterants in the precious metal market, and flags the offending elements with a pop-up alarm.
7Intelligent curve matchingthe algorithm automatically identifies the Au, Ag, Pt or Pd matrix and loads the corresponding calibration curve, eliminating errors caused by selecting the wrong curve.
8Fast and accuratea stable and reliable result is obtained in only 60 seconds, which greatly shortens the waiting time in trading, recycling and quality inspection.
9High-definition visual monitoringa built-in HD camera and high-brightness LED lighting present a clear live view of the sample on the screen throughout the test, preventing errors caused by improper sample placement.
10Dynamic real-time display and instant valuationthe software updates the elemental percentages and the gold karat value every second; the operator can enter the current gold price and sample weight and the software immediately calculates the actual value of the sample from the measured purity.
11One-key testingafter the sample is placed, a single key press completes the whole test sequence automatically.
12Refined appearancecompact body with flowing lines, suitable for a professional laboratory, a precious metal trading counter or a brand showroom.

IV. Notes

1. For powder samples the target elements must be Au, Ag, Pt or Pd; the powder must be ground, thoroughly mixed and pressed into a dense pellet, and the sample should be sent to the factory for calibration beforehand.

2. For liquid samples the target elements must be Au, Ag, Pt or Pd; the concentration range of the sample must be specified and the sample should be sent to the factory for calibration beforehand.
