OBJECTIVE
To study the stability of tetramine in blood samples under different environment temperatures.
METHODS
The tetramine samples in 0.5 microg/mL concentration were stored in the environment temperature at 45 degrees C, 25 degrees C and 4 degrees C. The tetramine concentration were measured by GC-MS in 1, 3, 12, 18 and 39 days, respectively. And then the results of measurement were analyzed by SPSS software.
RESULTS
At 45 degrees C and 25 degrees C, the concentration of tetramine changed without distinctly in first 3 days and declined significantly from 4 days to 12 days. Thereafter it declined more slowly. At 4 degrees C, the concentration of tetramine changed without distinctly in 12 days and declined significantly from 13 days to 18 days. Thereafter it declined more slowly.
CONCLUSION
The concentration of tetra mine in blood samples is stable in 3 days. Thereafter it declined gradually. Temperature also influences the concentration of tetra mine.
目的
研究不同环境温度下血液样本中毒鼠强的稳定性。
方法
将浓度为0.5微克/毫升的毒鼠强样本分别储存在45℃、25℃和4℃的环境温度下。分别在第1、3、12、18和39天通过气相色谱-质谱联用仪（GC-MS）测定毒鼠强浓度。然后用SPSS软件分析测量结果。
结果
在45℃和25℃时，毒鼠强浓度在最初3天无明显变化，从第4天到第12天显著下降。此后下降速度较慢。在4℃时，毒鼠强浓度在12天内无明显变化，从第13天到第18天显著下降。此后下降速度较慢。
结论
血液样本中毒鼠强浓度在3天内稳定。此后逐渐下降。温度也会影响毒鼠强的浓度。
