人血浆中维生素C的浓度受储存时间和温度以及所用稳定剂种类的影响。样品在25°、4°、− 20°和− 70°的温度下储存长达21天。本研究中使用的稳定剂包括三氯乙酸（TCA）和偏磷酸（MPA）。血浆维生素C在-70 ° C下储存时在TCA或MPA中表现出最大的稳定性。其他储存条件测试产生不太准确的维生素C值。
Vitamin C concentration in human plasma was shown to be affected by storage time and temperature as well as by the kind of stabilizer used. Samples were stored for periods of time up to 21 days at temperatures of 25°, 4°, − 20°, and − 70°. Stabilizers employed in this study included trichloroacetic acid (TCA) and metaphosphoric acid (MPA). Plasma vitamin C demonstrated maximum stability in TCA or MPA when stored at − 70°. Other storage conditions tested yielded less accurate vitamin C values.
