Introduction

1. Background and significance of the standard

GB/T 34536—2017 "Determination of nitrogen concentration in natural gas - scintillation vial method" is one of the important technical standards in my country's natural gas industry. It mainly stipulates the method of determining the concentration of hydrogen (²²²Rn) in natural gas using the scintillation vial method.

2. Principle and steps of the method

Step name	Operation points	Precautions
Scintillation vial treatment	Connect the scintillation vial to the vacuum pump with a latex tube, and repeatedly evacuate 3-5 times or purge with nitrogen for 3-5 minutes.	Ensure that the inner and outer walls of the scintillation vial are clean and dust-free.
Background measurement	Set the measurement interval to 5 minutes and perform three consecutive counting measurements.	Record the average count for 15 minutes as the background count J₁.
Sampling	According to GB/T13609, use latex tubes to connect the dryer, dust filter, scintillation bottle and rotor flowmeter, and adjust the natural gas flow to 1-4 L/min.	Record the temperature and atmospheric pressure at the sampling point.

Application Case

A natural gas company uses this standard method to detect the hydrogen concentration in the pipeline during gas production. The scintillation bottle method ensures the accurate collection of gas samples and the efficient counting of the radioactivity monitor.
