Principle and Gas flow diagram
The sample is placed in a graphite crucible and the crucible is maintained between the upper and the lower electrode of the impulse furnace. A high current power passes through the crucible to create a high temperature.
The oxide in the sample reacts with the graphite crucible, and is extracted as carbon monoxide (CO), and carried together with the carrier gas. The extracted gas is directly analysed after the dust filter. According to the oxygen concentration, it is determined by CO or CO2 after pass throw oxidizer (Copper Oxide) with a non-dispersive infrared.
The Hydrogen is determined with a non-dispersive infrared analyser as H2O after H2 passes through the oxidizer (Copper Oxide).
The Nitrogen in the sample is extracted as nitrogen gas (N2) and its concentration is determined by a thermal conductivity detector (TCD).
Features
- Equipped with various navigation functions
蓝鲸体育直播 provides our customers with full support, from analysis and maintenance to recovering from problems, by taking advantage of our know-how developed through long years of experience by their side. Smooth operation of the analyzers contributes to reducing working hours. - Rich lineup of options
In addition to the auto sampler, auto-cleaner, and automation systems for supplying crucibles that were developed to reflect the needs of customers, the fully automated analysis option reduces labor for analysis and realizes stable analysis. We also offer optional units according to various samples including a halogen trap unit.
Fast measurement
蓝鲸体育直播鈥� s proprietary sequence algorithm reduces the analysis cycle time* * Patent applied
Ultratrace, high accuracy, high reproducibility
蓝鲸体育直播鈥� s proprietary detectors
The EMGA Series has NDIR gas detectors developed, designed, and manufactured by 蓝鲸体育直播. Based on detailed design and sophisticated production technology, these detectors are manufactured with close attention to all processes, from the polishing and assembly of components to adjustment and confirmation of stable operation. Our thorough quality control provides stable and highly reliable measurement for an extended period with the EMGA Series. In addition, we have also developed the TCD detector in-house so that these analyzers can demonstrate the best performance.
Reduced maintenance work hours and frequency
Use of a new mechanism for replacing consumables
- Easy replacement of lower electrodes* * Patent applied
With the new design for replacing the chip all you have to do is remove the lower electrode cap to replace the chip. This mechanism reduces the amount of time it takes to approximately 1/10.
- Dust filter* * Patent applied
With the new mechanism for replacing the dust filter you only need to replace the thin filter inside the filter holder. This has also reduced the filter replacement frequency to 1/10 (replacement required after about 500 uses).
- Significantly reduced carrier gas consumption* * Patent applied
The number of measurements that can be performed with one gas cylinder has significantly increased from about 1,400 times to 2,300 times when a 47-liter cylinder is used.
Various navigation functions that fully assist analysis
The EMGA Series' unique software includes 蓝鲸体育直播's analysis know-how, "Analysis Navigation" that assists in proposing optimal measurement conditions and operating procedures according to the measurement sample, and maintenance work that can be done by checking the maintenance procedure in a video. "Maintenance Navigation" and "Troubleshooting Navigation" that navigates from the alarm display to the recovery of the device are installed.
1. Analysis Navigation
2. Maintenance Navigation
The user is led through maintenance work items, procedure, and method. They check the videos which shows of actual maintenance work, ensuring safety and thorough work, and reducing differences in maintenance work performed among individuals, contributing to stable operation of the analyzer.
- Maintenance Navigation Screen
- Maintenance Screen
User can perform operations, including solenoid valve operation and leak checks, that are necessary for maintenance work.
- Maintenance Counter Screen
The current value and threshold for each maintenance item are shown. If the set threshold is reached, you can display an alarm about the need for maintenance.
3. Troubleshooting Navigation
The user is led to the best recovery method from the alarm being displayed screen that explain of recovering with using images and videos. Suggestions on troubleshooting steps that can be applied on site will lead to reduced down time of instrument.
Troubleshooting Navigation Screen
Accelerated labor saving through automated analysis
Rich customization options
The EMGA Series features a number of functions required for the automation of measurement, saving labor for measurement work and ensuring safety.
With a 鈥渃rucible loader鈥� for automatically supplying crucibles, an 鈥渁uto-cleaner鈥� for automatically cleaning electrodes and disposing of crucibles, an 鈥渁uto sampler鈥� for automatic loading of samples, and the 鈥渁utomated analysis system,鈥� the analyzers achieve a clean and safe measurement environment that will not dirty the measurement operator鈥� s hands. In addition, the optimized automation sequence simplifies operation down to just loading the sample and pressing the start button after entering the preset (measurement conditions and sample name).
- Crucible loader unit (Automated crucible supply system)* * Patent number : US8172072, EP2138849, CN105510614, JP05086918, JP05068702
Precise capture and positioning of crucibles by rotary mechanism. Maximum stock: 100 pcs. Compatible with stanadard/long type crucibles.
- Auto-cleaner* * Patent number : JP05198947, JP05155751
Two rotating brushes clean the upper and lower electrodes after each measurement. The vacuum cleaner prevents contamination by removing dust.
- Auto sampler
Samples and fluxes are automatically loaded. Up to 22 samples and fluxes can be set.
- Full automation analysis system * Patent number: JP05043802
This system supports full automation of analysis work. It has a complete safety mechanism and also supports communication with an online host system. The system can be customized according to the measurement conditions and communication specifications of customers. (Example: from weighing to completion of the analysis)
* The specification of the options shown in the photos may be different from those of actual options.
