We have found that disposable sterile plastic syringes can leach free radicals into the fluids they hold. The free radical we observe appears to be a nitroxide (aminoxyl radical) because in aqueous solution it produces a 1:1:1 three line spectrum with a hyperfine splitting constant of 16.9 G.
我们发现一次性无菌塑料注射器会将自由基释放到其所盛装的液体中。我们观察到的自由基似乎是一种氮氧化物(氨基氧自由基),因为在水溶液中它会产生一个三线谱,其超精细分裂常数为16.9高斯,强度比为1:1:1 。
