Features

1. High Precision

① Self developed ultra-low drift infrared cell (Patent No. ZL200920318535.8) adopts the high-performance infrared light, electronic components, optical glass as well as infrared light receiving device. The drift of infrared cell is greatly reduced (calibrate every 3 hours or even longer time).

② Self developed ultra low temperature drift TCD and thermostatic diffusion type TCD ensure the stability of TC reference line.

2. High Automation and Test Efficiency

① Autoloader with 34 position, automatic sample introduction and test.

② Analysis time of elemental analyzer for a single sample is less than 5 minutes, new samples can be added or replaced during the analysis process.

③ Combustion crucible can be replaced automatically (Patent No.: ZL200710303473.9), no disassembling, no cooling, no damage to the furnace and combustion tubes. Operator is away from high temperature and danger.

3. Humanization Design and Convenient Operation

① Easy and convenient for gas leakage check, operators only need to click on the software.

② Convenient to replace the Furnace Reagent. With separate design of combustion furnace and reagent furnace, reagent can be easily and safely replaced with the minimal amount of effort.

③ Floor standing design with superior wheels and wheel locking device for all elemental analyzers, it’s convenient to shift the instrument from place to place.

④ Enlarged combustion crucible for elemental analyzer can greatly reduce the frequency of crucible changing.

4. Low Operation Cost

① Helium consumption is only 0.7L/min for each test, which reduces the gas consumption greatly. Nitrogen analysis part can be stopped optionally if necessary.

② Oxygen with purity of 99.5% can meet the test requirement of all elemental analyzers.

5.Intelligent Control

①Easy-to-use Windows-based software for all elemental analyzers, easy data handling, real time data can be transmitted by internal network.

② With CAN bus interface, several elemental analyzers can be controlled by a single PC without mutual influence.

③ It can be connected with balance and network by standard interface RS232.
