| titleOfInvention | NMHC analytical equipment and method |
| abstract | The present invention relates to a kind of NMHC analytical equipment and method, belong to organic gas detection technique field.This analytical equipment includes: six-way valve, quantitative loop, the first cylinder, the second cylinder, multiple-way valve, molecular sieve filled pipe, the first air source and detector.By the exquisite cooperation of said elements, first six-way valve and multiple-way valve are located at load condition position, gas to be measured is made to remove NMHC therein by molecular sieve, it is filled in the first cylinder and the second cylinder as background gas, subsequently six-way valve and multiple-way valve are all located at sample introduction mode bit, zero level compressed air is made to promote the gas in the second cylinder, quantitative loop, the first cylinder to sequentially enter detector, i.e. using the background gas in the second cylinder and the second cylinder as baseline.Avoid when methane concentration is close to THC concentration, the problem of the error detection value superposition that direct minusing causes, there is testing result accurate, the advantage that method is reliable and stable. |
