The ESI XRF spectrometer can be widely used in the application fields:

Alloy/scrap metal analysis. Extinguish different type of stainless steel of 304/316/321 by analyzing the metal content in the sample within 3 seconds.
Sulfur/metals in oil/lubricant complying with ASTM-D4294(EDXRF), ASTM-D7039(WDXRF), ASTM-D2622(WDXRF), ASTM-D5453(UVF), ISO 8754(EDXRF)
Jewelry/ precious metal. Identify the karat of the gold (9k, 14k, 18k, 22k etc.) sample in one second
RoHs compliance (Cr, Cd, Pb, Hg, Br, As, Se, Sb, Bi). Fast screen the 8 heavy metals restricted by XRF spectrometer within 2 minutes per sample.
Mineral and mining. Copper and gold mining exploration by bringing the handheld XRF to test the Cu and Au content in the field.
Soil heavy metal pollution measurement.
Coating/ Plating thickness measurement- Non-destructive XRF analysis of both coating thickness and coating material concentration analysis
At the same time, ESI xrf element analyzer are also popular in the industries cement, clinker and cement materials, chemistry, cosmetics, education and scientific research, environment pollution, food and food ingredient, forensics and conservation, plastic and rubber, process control, car and catalyst, semiconductors and etc.
