Fast intelligent calibration method

Quick intelligent sulfur analyzer operation method:

1, before the formal test, first do 1 ~ 2 waste samples, add solution sulfur content, to the end of the electrolysis potential can do positive sample. When doing a positive sample, weigh 0.05g of air-dried sample with a particle size of less than 0.2mm (weighed to 0.0002g) on ​​a porcelain boat, cover a thin layer of tungsten dioxide with the waste sample, and place the porcelain boat into quartz. On the tray.

2. Open the computer and double-click on the “Sulfur Detection Program” icon. A program interface appears on the screen. The contents are: “Enter necessary data”, “Open existing report”, “Don’t do sample”, “Do it right”, “ "Print current report" and "Exit system", the user can select one of them as needed.

(1)、"Enter necessary data": Click this item to input data such as "send sample time", "sample delivery unit", "room temperature", etc., click "OK" (you can also temporarily not input relevant data, direct single Click "OK" because the program prompts you again for the necessary data when doing something positive.)

(2) Open Existing Report: Click this item to select and open the report folder, select the report to open, and click Open. To print the report, click the printer icon.

(3) "Defective sample": Click this item and the system prompts "put coal sample" (click "OK" to start the test; click "Cancel" to cancel the operation.) Click "OK", the sampler starts working, the waste sample test starts, and the screen shows the test condition. After the waste sample test is completed, the system prompts "You can do trial now", click "OK", and then you can do positive sample.

(4)、"Do the right thing": click this item, the system prompts "Whether input necessary data", if you want to input, click "Yes", after input, click "OK", save it; if you do not input, Click "No", the system prompts "put coal sample" (click "OK", the test begins; click "Cancel" to cancel the operation). After adding the coal sample, click “OK”. A table appears on the screen. The first column of the table is the number of trials, the second column is the weight of the coal sample, and the third column is the sulfur content. Click the "Start" button at the bottom of the screen, press the prompt to enter the weight of the coal sample, click "OK", a small display box appears on the screen, the sample feeder starts to work, and the computer-driven sample stick pushes the porcelain boat at 700 °C respectively. Stay 45 seconds, 1150 °C stay 4 minutes 45 seconds, after the sample burns, Coulomb titration automatically. When the electrolytic indicator light is displayed in the display box there are numbers, the test is in progress at the table. Wait until the quartz tray and porcelain boat return In situ, the sulfur content is listed in the table. The screen prompts “The sample is completed, please click OK to exit”. After clicking “OK”, put the second coal sample and click the “Start” button at the bottom of the screen. According to the above method to do the next coal sample. Such a cycle, you can do more than coal samples. When you have finished 3 or more coal samples and exit, click "Exit". The system will prompt "Save or not" and click "Save".

(5), "Print current report": Click this item, select the report you want to print, click "Print current report" to print.

(6) "Exit system": Click this item to exit the sulfur measurement program.

3. After the experiment is finished, turn off the air pump and stirrer. Turn the power conditioner on the furnace to the minimum, turn off the power switch, discharge the electrolyte, and clean the electrolytic cell and the electrode with distilled water. The electrolyte can be reused. The length of time is based on repeated use. The number of samples and the sulfur content of the sample may vary. If the pH of the electrolyte is less than or equal to 1, the electrolyte should be discarded.

The test is preferably performed continuously. If the intermediate interval is long, add a sample before doing positive samples. Enter the moisture value of the sample into the computer. Otherwise, the result is the analysis of the base sulfur content.
