How to calculate the consumption of calibration gas for online analysis instruments in modern coal chemical industry
Thread Content
Which expert can explain how to calculate the amount of standard gas required for online analysis instruments in modern coal chemical industries, and separately, the amount of standard gas needed for analysis experiments? What is an appropriate amount of standard gas for analytical instruments?
Do online analysis instruments for OCU devices require standard liquids? If I use it, how much does a standard bottle of liquid cost approximately?
The specific values are not fixed. It should be related to your specific circumstances and system PID tuning.
The calibration cycle specified for different analytical instruments and products from various manufacturers varies, resulting in different usage amounts； Suppliers are relatively accurate in estimating this figure; it is recommended to consult the system integrator.
There is no fixed value for this; each time calibration is performed, part of the calibration gas is fed into the meter while the rest is released through a bypass. The amount of gas that goes through the bypass is controlled manually. Moreover, the actual conditions vary from one meter to another, as well as from one company to another. Meters that provide stable readings may only need to be calibrated once every month or two, whereas those that give unstable readings or whose measurements are often questioned in terms of accuracy may require calibration many times. Therefore, it’s impossible to determine a fixed value.
You can ask the manufacturer; after all, calibration solutions are very expensive.
Should it be calculated based on the specific consumption of each instrument? It’s possible to keep track of how many analyzers are in use, which ones require standard gas, what type of standard gas is used, how much standard gas is needed for each calibration, and how often calibrations need to be performed. All of this can surely be counted or estimated. Doesn’t your brain have any brains in it? Is your head filled with XX soup?
It depends on the number of calibration times and the amount of bypass venting, I guess
Yes, we generally provide two vials of standard solution per instrument, with a shelf life of one year. The standard solutions for OCU are relatively expensive, with complex components
