专利摘要:本发明涉及一种集成FESEM和LDI‑TOF‑MS分析系统,并且提供如下一种集成FESEM和LDI‑TOF‑MS分析系统:其能够对要被分析的单个样品进行FESEM分析和LDI‑TOF‑MS分析,而不将样品暴露于大气。 专利权项:1.一种集成分析系统,包括:第一样品保持器,所述第一样品保持器中形成有第一封闭空间;第二样品...
Kinds of new synthetic bis(diazanaphthenone) compounds were identified bymatrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF MS). 采用基质辅助激光解吸电离飞行时间质谱 (MALDI TOFMS) ,以 2 ,5 二羟基苯甲酸 (DHB)为基体对10种合成的新型双二氮杂萘酮化合物进行了质...
Here, we showed that the LDI-TOF-MS recognized almost all AFP-negative HCC. The sensitivity and specificity were obviously superior to AFP in HCC: only 2 of 137 HCCs (1.46%) were misclassified as healthy controls. In contrast, AFP positive and AFP negative HCCs were not readily ...
利用基质辅助激光解吸电离飞行时间质谱(MALDI-TOF MS)对差异蛋白进行了鉴定,结果发现转酮酶、S-腺苷甲硫氨酸合成酶、二氢硫辛酰胺脱氢酶和脂肪酸合成酶在植物诱导化学防御中具有重要的作用,其中脂肪酸合成酶与茉莉酸代谢通路相关。 3. Its molecular mass was determined by MALDI-TOF MS. 聚乙二醇单甲醚与琥珀酸...
本文采用激光解吸电离飞行时间质谱(LDI-TOF-MS)法快速测定了1H-2,3-二氢-1-吡咯里嗪酮系列衍生物,实验中不需加入基质即可得到每一个化合物准确分子量,而且实测值与理论计算值相吻合,获得了令人满意的结果。实验证明本方法对检测该类化合物的分子量快速、简捷、准确。关键...
its surface, enhance the stability of this hydroxyl-rich Ti3C2(Ti3C2(OH)x), and evaluate the analytical performances of Ti3C2(OH)x-assisted laser desorption/ionization time-of-flight mass spectrometry (LDI-TOF-MS) for small-molecular natural compounds in complex samples. The developed Ti3C2(OH...
