Introduction

Background of Standard Revision and Technological Evolution

This standard replaces GB/T 14677-93. The main technical upgrades include:

Revision dimensions	1993 edition	2010 edition
Detection components	5 types	8 types (newly added ethylbenzene, isopropylbenzene, etc.)
Standard solution matrix	Carbon disulfide	Methanol
Chromatographic technology	Packing column only	Added capillary column secondary desorption technology

Core method principle

Sampling was performed at room temperature using Tenax adsorption tubes, and the benzene series were desorbed using a thermal desorber (250°C), followed by separation and detection using a gas chromatography-FID system. Critical control points:

Aging of sampling tube: 350℃ nitrogen for 120 minutes
Safe sampling volume: 6.2L benzene/38L toluene (at 20℃)
Storage conditions: 4℃ light-proof and sealed for ≤30 days

Instrument configuration requirements

Typical equipment combination plan

Thermal desorber	Temperature range 40-300℃, with secondary cold trap focusing
Gas chromatograph	FID detector, recommended capillary column: PEG-20M (30m×0.32mm×1.0μm)
Sampling device	Oil-free pump with flow range of 0.01-0.5L/min

Key indicators of quality control

Parameters	Requirements
Parallel sample deviation	＜25%
Recovery rate of the second sampling tube	＜20%
Intermediate concentration calibration	Relative error≤20%
Detection limit (capillary column)	Benzene: 5.0×10^-4 mg/m³

Implementation suggestions

Give priority to the capillary column solution to improve the separation of p-xylene/m-xylene
Regularly verify the adsorption efficiency of the Tenax tube, and replace the adsorbent when the recovery rate of the second sampling tube is >15%
For indoor air monitoring, it is recommended to control the sampling flow rate at 50-100ml/min
