Our History
ESI (Efficiency Scientific Instrument Co.,Ltd) was founded in 2010 to produce the high voltage x-ray power supply. From 2012, ESI started to develop and manufacture the X-ray tubes and DPP(Digital Pulse Processor). In 2019, ESI was merged with Htek instrument, which is a high technology company and a recognized leader in the design and manufacture of state-of-the-art x-ray fluorescence spectrometer.
Today,With combined technological experience and advantages accumulated in both companies over the past years , ESI is a worldwide market producer of advanced x-ray fluorescence system for complete solutions in elemental analysis with thousands of machines installed and operative all over the world. Every year high percentage of its revenue is invested in R&D with the aim to improve the analysis performance

Product Application
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.
