摘要：【中文】本发明属于生物材料检测领域，具体涉及一种基于GC‑MS与酶化学法检测生物样品中尿素含量的方法。该方法包括如下步骤：（1）检测条件；（2）样品处理；（3）图谱分析；（4）标准工作曲线样品溶液的制备；（5）含量计算。本方法通过柱前衍生化气相色谱‑质谱联用法，能够有针对性的检测出生物样品中的尿素含量，该方法利用尿素酶能专一地分解尿素地特性，将尿素转化为氨，再利用七氟丁酰氯与之较为迅速、完全地反应，使不能被GC‑MS检测地尿素得以被检测与定量。该方法灵敏度较光谱法更高，线性关系较好。 【EN】The invention belongs to the field of biological material detection, and particularly relates to a method for detecting urea content in a biological sample based on GC-MS and an enzyme chemistry method. The method comprises the following steps: (1) detecting conditions; (2) processing a sample; (3) analyzing a map; (4) preparing a standard working curve sample solution; (5) and (4) calculating the content. The method can specifically detect the urea content in the biological sample by a pre-column derivatization gas chromatography-mass spectrometry combined method, converts urea into ammonia by utilizing the characteristic that urease can specifically decompose urea, and then utilizes heptafluorobutyryl chloride to react with the ammonia rapidly and completely, so that the urea which cannot be detected by GC-MS can be detected and quantified. The method has higher sensitivity and better linear relation than a spectroscopic method.
