含硫化合物的气相色谱检测响应特性研究

利用气相色谱（配炎焰光度检测器）对二硫化碳（ＣＳ２）、甲硫醇（ＣＨ３ＣＨ）、甲硫醚（ＤＭＳ）和二甲二硫醚（ＤＭＤＳ）４种含硫物质进行了分析检测，着重讨论了气相色谱仪的各项参数对几种含硫物质响应和分离效果的影响。结果表明：该分析对含硫气体的最小检测浓度达到ｐｐｂ级。在各项参数中，色谱柱温度在Ｎ２压力对各含硫物质响应和分离度影响最大，汽化室和检测器温度及空气压力对它们的影响相对较小。     

Immediate prenatal diagnosis of Zellweger syndrome by direct measurement of very long chain fatty acids in chorionic villus cells

We report a gas chromatographic-mass spectrometric method which allows the very long chain fatty acids content of trophoblastic tissue to be directly measured in samples collected by biopsy between 8 and 11 weeks of gestation. This method has been successfully applied to the detection of fetal Zellweger syndrome in two pregnant women who had previously delivered affected infants. In one of them, increased concentrations of C26:0 (0.254 versus 0.108±0.035 μ/mg proteins) and C24:0 (1.32 versus 0.815±0.325 μ/mg proteins) in trophoblast indicated that the fetus had Zellweger syndrome, a diagnosis confirmed by pathological findings after abortion. In the second case, the pregnancy was allowed to proceed, on the basis of normal concentrations of very long chain fatty acids in trophoblastic tissue, and its outcome was actually a healthy newborn.

Direct hydride derivatization of methyl- and ethylmercury chlorides in aqueous solution with KBH4

A convenient hydride derivatization procedure of methyl-and ethylmercury chlorides to volatile hydrides was reported. In sealed vials methylmercury and ethylmercury compounds in acidic aqueous solutions were converted into their volatile forms by the reaction with potassium tetrahydroborate(KBH4) and elvolved to the headspace of the vials. The gaseous analytes in the headspace were extracted and concentrated by solid phase microextraction(SPME) and injected into gas chromatography (GC) for separation and identified by mass selective detector(MS).
