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
ESI is a SIP(Suzhou industry park, China) based company specialized in XRF(X-ray fluorescence) instrument for non-destructive material analysis, coating thickness measurement and material testing. Our mission is to provide the rugged user friendly xrf analytical system to meet with the most difficult element analytical needs.
-Alloy/scrap metal analysis. For example, extinguish different type of stainless steel of 304/316/321 by analyzing the metal content in the sample within 3 seconds.
- Jewelry/ precious metal. For example, 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 law
- Mineral and mining. For example, 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.
-Sulfur in oil/lubricant complying with ASTM-D4294, ASTM-D7039, ASTM-D2622
-Coating/Plating thickness measurement
The XRF can also be applied to more industries and fields because of the features:
-Fast. Test results can be obtained from 1-200 seconds.
-Accurate and precise.
-Non-destructive. No sample preparation or very simple procedure is needed.
-72 elements tested in one machine. Elements from Sodium to Uranium in the periodic table can be measured.
