Objective Analyze and evaluate the measurement uncertainty of phenylethanolamine A residue in beef using liquid chromatography tandem mass spectrometry. Methods By analyzing the detection process and mathematical model, the main sources of uncertainty in the residual amount of phenylethanolamine A are determined: uncertainty caused by detection equipment, uncertainty caused by standard and sample weighing, uncertainty caused by laboratory temperature, uncertainty caused by transfer and constant volume, uncertainty caused by sample pretreatment, and uncertainty caused by experimental repeatability. Results The measurement uncertainty of each component was calculated and the relative standard uncertainty $\left({{u}_{\mathrm{{rel}}}={0.11}}\right)$ was synthesized for the detection of phenylethanolamine A residue in beef by liquid chromatography-tandem mass spectrometry. The expanded uncertainty of the determination results was $\mathrm{U}\left( X\right)={0.11}\mathrm{{gg}}/\mathrm{{kg}}$ . The detection result of measuring phenylethanolamine A in beef by liquid chromatography tandem mass spectrometry was: $X=\left({{0.51}\pm {0.11}}\right)\mathrm{{\mu g}}/\mathrm{{kg}}, k =2$ . Conclusion The detection equipment had the greatest impact on the measurement uncertainty of phenylethanolamine A residue, followed by sample pre-treatment, experimental repeatability, and transfer and constant volume. In daily testing, attention should be paid to the condition of the instruments and equipment, timely verification and calibration should be carried out, the experimental process, transfer and constant volume operation should be standardized, so that to minimize the impact of the above factors on measurement uncertainty as much as possible.

Through advanced technology and practical exploration, establish and improve a low-carbon economic system, expand the scale of related industries, and promote economic structure optimization. The construction plan of the testing laboratory studied in this article has negative emissions after measures such as independent emission reduction, renewable energy, and carbon sequestration during the operation phase, which can be defined as a carbon neutral laboratory. The construction of zero carbon laboratories is one of the important actions for global environmental protection and energy conservation and emission reduction, and is also regarded as the actual implementer of the ecological civilization concept advocating sustainable development. From this, we can gain a deeper understanding and promote the development direction of humanity towards a sustainable and low-carbon future.

ABSTRACT: Against the backdrop of accelerating the modernization process of the military, testing and evaluating the adaptability of equipment environment has become particularly important. However, the current equipment testing and appraisal work cannot meet the needs of equipment testing and evaluation under the new system, and it is urgent to systematically sort and analyze it. China has established a relatively complete experimental system, and has made significant progress in both hardware equipment construction and training of experimental personnel. In the evaluation test of single system weapons and equipment, its management and technology are also relatively mature and complete. However, there are new challenges in equipment testing. Therefore, this article proposes an overall approach for equipment environmental adaptability testing and verification under a new system of digital transformation in equipment testing and identification. It grasps the key links in the entire process of testing and identification, spans various stages, and combines virtual and real to comprehensively evaluate equipment.
