Introduction

Standard Technical Interpretation

QX/T 214-2013 is a professional technical specification formulated by my country's meteorological industry for the pre-treatment and post-treatment of stainless steel sampling cylinders in halogenated greenhouse gas monitoring. The standard specifies the control requirements for core parameters such as temperature, vacuum, and gas replacement during the sampling container processing process.

Comparison of system composition

Component type	Single-port sampling cylinder system	Dual-port sampling cylinder system
Temperature control	100℃ constant temperature	100℃ constant temperature
Vacuum requirement	≤4Pa	≤4Pa
Processing flow	3 vacuum pumping-inflating cycles	4 vacuum pumping-inflating cycles
Special treatment	12 hours balance	12 hours of gas flushing

Key technical points

Core steps of pretreatment

System status detection: ensure that the vacuum degree is less than 4Pa and the filling gas pressure is greater than 1×10⁵Pa
Heat treatment stage: 3-4 vacuum/gas cycles at 100℃
The single-port cylinder requires 12 hours of pressure balance, and the double-port cylinder requires 12 hours of flushing at a flow rate of 40mL/min

Post-treatment differences

The outlet valve must be kept closed during double-port cylinder treatment
The final filling pressure is uniformly required to be 1×10⁵Pa
After the treatment, key parameters such as vacuum degree, temperature, and holding time must be recorded

Implementation recommendations

Operational specifications

It is recommended to establish an electronic file of the sampling cylinder to record the following for each treatment:

Treatment type (pre-treatment/post-treatment)
System temperature curve
Vacuum degree reaching standard time
Filling gas batch number

Quality control

Regularly:

Calibrating the accuracy of the temperature control unit (±1℃)
Testing the ultimate vacuum degree of the vacuum pump
Analyzing the filling gas background concentration

Background of standard evolution

This standard is based on the definition of terms in QX/T 125-2011 and is aimed at Special requirements for stainless steel sampling cylinders in halogenated greenhouse gas monitoring. Compared with earlier methods, the main improvements include:

Clearly distinguish between single/double-mouth container processing procedures

Added recommended solutions for low-temperature cold trap water removal
