气相色谱-电子捕获负化学源-低分辨质谱法测定人体血液不同组分中短链及中链氯化石蜡

open access: yesSe pu = Chinese journal of chromatography, 2023
短链及中链氯化石蜡(SCCPs和MCCPs)因其持久性、生物毒性、富集性及长距离迁移等特点受到广泛关注。随着SCCPs和MCCPs在多种环境介质中的广泛检出,人类面临的暴露风险逐渐升高,因此开展人体内SCCPs和MCCPs的暴露评估具有重要意义。了解氯化石蜡(CPs)及其各同族体在血浆和血细胞中的分配行为及分布特征能够更好地掌握其在人体内的积累和循环情况,有助于准确、有效地评估CPs在人体内的暴露水平。本研究建立了Percoll不连续密度梯度离心方法,将人体血液分离为血浆、红细胞、白细胞和血小板4种组分,

快速溶剂萃取-离子色谱-质谱法测定人体血液、尿液中的氟乙酸

open access: yesSe pu = Chinese journal of chromatography, 2023
建立了快速溶剂萃取-离子色谱-质谱法测定人体血液、尿液中氟乙酸的方法。以去离子水为萃取溶剂,使用快速溶剂萃取仪处理血液和尿液样品,取上清液依次经超滤管和0.22 μm水相针式滤膜净化,稀释50倍后进样检测。采用Ion Pac AS20离子色谱柱以15.0 mmol/L的KOH溶液为淋洗液进行等度淋洗,流出液通过抑制器后进入三重四极杆质谱,在负离子、多反应监测模式下检测,外标法定量。结果表明,氟乙酸在0.5~500.0 μg/L范围内线性关系良好(r>0.999),检出限和定量限分别为0.14、0.47 ...

血液与神志关系剖析

open access: yes中医与中药材研究, 2022
中医认为心主神志,西医认为脑主神志。本文专注剖析血液对神志的影响。本文基于古今医学文献以及临床实例论证血液对神志的影响,并进行分析,探讨血液影响神志的临床意义。通过对文献的分析,以及基于对生理和病理的分析,加上对疾病的诊断与治疗,以及中医理法方药的分析与论证,本文认为“血主神志”具有一定的道理。

液液提取-固相萃取-高效液相色谱-串联质谱测定人体血液中16种有机磷酸酯

open access: yesSe pu = Chinese journal of chromatography, 2021
人体体液中有机磷酸酯(OPEs)浓度的测定对于了解人体OPEs的暴露水平以及评估人体健康风险具有重要意义。然而,目前的研究大多数集中于尿液中OPEs代谢物含量的分析测定,将其作为人体OPEs暴露的生物标志物,而对人体血液中OPEs的分析研究较少,仅有的少量研究涉及的OPEs种类有限。该研究在优化前处理过程(固相萃取,SPE)和色谱分离的基础上,建立了人体血液中16种OPEs的超高效液相色谱-串联质谱(UPLC-MS-MS)测定方法。血液样品经过乙腈摇床萃取后,经ENVI-18 SPE小柱净化 ...

高效液相色谱-串联质谱法同时检测血液中3种季铵盐类肌松剂

open access: yesSe pu = Chinese journal of chromatography, 2021
维库溴铵、罗库溴铵和泮库溴铵是一类广泛使用的非去极化肌松剂,使用过程中引起过敏反应甚至死亡的情况时有发生,快速检测血液中该类肌松剂的浓度,可为临床早期诊断提供有价值的信息。该类肌松剂为强极性的季铵盐类化合物,在反相色谱柱上难以保留,主要采用离子对色谱法进行分离。采用离子对色谱法时,加入的离子对试剂有离子抑制作用,可降低质谱灵敏度,还会污染质谱系统。该文建立了高效液相色谱-串联质谱(HPLC-MS/MS)同时检测血液中3种季铵盐类肌松剂的检测方法。血液样品经稀释、高速离心后,上清液过Bond Elut ...
