Introduction

1. Background of standard formulation and technical evolution

GB/T 37101-2018 was drafted in accordance with GB/T1.1-2009 rules and was proposed and managed by the National Technical Committee for Standardization of Key Product Inspection Methods for Quality Supervision. This standard is mainly aimed at the determination of MOCA in polyurethane materials and is applicable to the detection of other polymer materials after verification.

2. Overview of the determination method

The analysis was performed using a dichloromethane ultrasonic extraction method combined with a gas chromatography-mass spectrometer (GCMS). The specific steps include sample preparation, extraction, instrument determination conditions and quantitative analysis.

3. Comparison of standard frameworks

Dimensions of standard frameworks	GB/T 37101—2018	Comparison description
Scope of application	Determination of MOCA in polyurethane materials and other polymer materials	Highly targeted, suitable for testing a variety of materials
Requirements for reagents	Analytical grade dichloromethane, chromatographic grade methanol, etc.	Ensure the accuracy and repeatability of the results
Instruments	GCMS coupling instrument, electronic balance, ultrasonic extractor, etc.	High configuration requirements to ensure data accuracy

4. Technical details and practical application cases

Case analysis: In the detection of a polyurethane sample, the MOCA content was measured to be 15 mg/kg using this standard method. By comparing the standard curve and mass spectrum characteristics, the result was confirmed to be accurate.

5. Implementation suggestions

The laboratory should be equipped with GCMS equipment that meets the requirements and calibrate the instrument regularly. Operators need to undergo professional training to ensure the standardization of sample preparation and analysis. It is recommended to establish a long-term stability monitoring mechanism for standard solutions to improve the reliability of measurement results.
