Based on over 50 years of experience in the development and application of infrared detection technology and over 30 years of experience in the research and manufacturing of EMIA series infrared carbon and sulfur analyzers, HORIBA has recently launched the high-frequency infrared carbon and sulfur analyzer EMIA Pro.

On the basis of maintaining the superior performance of the previous generation EMIA series infrared carbon sulfur analyzer, EMIA Pro further improves usability, durability, reliability, and adds powerful real-time support and assistance functions.

The newly developed unique and efficient automatic cleaning system enables the equipment to undergo over 200 maintenance free inspections. By optimizing the entire testing process, the analysis time for the entire process has been reduced by 20%, further improving analysis efficiency.

Instrument characteristics

1The detection range (measuring range) is wide, with a carbon detection range of 0.6ppm-6% and a sulfur detection range of 0.6ppm-1% when the sample volume is 1g. Moreover, by reducing the sample volume, the measuring range can be further expanded to 100%;

High frequency induction heating method with program temperature control function. The output power of the high-frequency furnace is 2300W, the frequency is 20MHz, and the heating temperature can reach 2000 ℃. It can fully heat and burn refractory materials, releasing carbon and sulfur completely;

The dust blowing device using HORIBA patented technology greatly improves the dust removal effect, enabling the furnace head to have a maintenance free cycle of over 200 times, greatly reducing maintenance workload.

The newly designed high-efficiency carrier gas refinement device is an optional component to ensure high purity of the carrier gas, thereby ensuring high detection accuracy.

The operating system combines touch screen operation and conventional operation. By analyzing the software program to automatically control the relevant parameters of the infrared detector;

The maintenance window can monitor all parameters of the system environment and automatically detect and diagnose the usage status of various electromagnetic valves and mechanical parts;

The software is easy to operate and has a user-friendly interface,. The dynamic display of the analysis result curve has mathematical and statistical functions, which can calculate the mean, standard deviation, relative standard deviation, range, etc. It also has functions such as graphic data storage, graphic comparison, differential operation of graphics, and release of curve segmentation and integration processing;

8 has data transmission function, and analysis data can be transmitted through the network in a timely manner;

9 has analysis condition setting navigation function, maintenance navigation function, and fault diagnosis navigation function, which can intuitively instruct the operator to set analysis conditions and perform various daily maintenance operations and fault cause analysis in the form of text and video, allowing even people who are not familiar with the instrument and equipment to smoothly complete daily testing and maintenance work;

10 has a log file function, which can record all operations, results, maintenance, etc., in order to understand the operation status of the instrument.

In response to changes in user application requirements, corresponding hardware upgrades can be made to the instrument system on-site to ensure that the instrument has functionality and application scalability.

Instrument principle

The analysis and testing principle of EMIA Pro is to use a high-power high-frequency heating furnace with controllable combustion to heat the sample:

1. The sample is heated and burned in an oxygen atmosphere by a heating furnace

2. Carbon and sulfur are oxidized into CO, CO2, and SO2

3. After dust removal, water removal, and flow adjustment control in the gas path, CO, CO2, and SO2 are sent to non dispersive infrared detectors (NDIR) for detection

Further determine the carbon and sulfur content in the sample.

The main components include a high-power controllable combustion high-frequency heating furnace, a new high-efficiency automatic cleaning system, an ultra wide dynamic response range 4-detector high-precision testing unit, and an operation control system with powerful real-time support and assistance functions.
