建立了高效液相色谱-示差折光检测器(HPLC-RID)法同时测定玻璃化冷冻液中4种保护剂和2种营养物质的含量。以0.01 mol/L硫酸溶液为流动相进行洗脱,采用BIO-RAD Aminex HPX-87H(300 mm×7.8 mm,9 μm)色谱柱分离,示差折光检测器(RID)检测,外标法定量。结果表明,在优化的色谱条件下,6种待测组分能有效分离,且在各自考察的质量浓度范围内线性关系良好,相关系数(
r
)均不小于0.999 9,检出限(LOD)和定量下限(LOQ)分别为0.009~0.025 mg/mL和0.030~0.085 mg/mL。阴性样品在低、中、高3个浓度水平下的平均加标回收率为99.8%~103%,相对标准偏差(RSD,
n
=3)为0.20%~1.8%。该方法简便、专属性强、准确度高,适用于玻璃化冷冻液中保护剂和营养物质的含量测定。
A method for determination of four cryoprotectants and two nutrients in vitrification solution was developed by
high performance liquid chromatography with refractive index detector(HPLC-RID). The samples were eluted by using 0.01 mol/L sulfuric acid as mobile phase,and the chromatographic separation was carried out on the BIO-RAD Aminex HPX-87H column(300 mm × 7.8 mm,9 μm). Refractive index detector(RID) was used for detection and the external standard method was applied for quantitative determination. Under this specific condition,the samples were well separated and showed good linear relationships with the correlation coefficients(
r
) not less than 0.999 9. The limits of detection(LODs) and the limits of quantification(LOQs) were 0.009-0.025 mg/mL and 0.030-0.085 mg/mL,respectively. The average spiked recoveries of the negative samples at three concentration levels were from 99.8% to 103%,and relative standard deviations(RSDs,
n
=3) were between 0.20% and 1.8%. The method is simple,specific,accurate and suitable for the determination of cryoprotectants and nutrients in vitrification solution.
