高温正相色谱/反相色谱(HTNPLC/RPLC)二维联用系统的构建与应用

为解决含水正相色谱与反相色谱联用过程中的谱带展宽问题,以高温正相色谱(HTNPLC)为第一维,室温反相色谱(RPLC)为第二维,分别建立了切割模式的二维液相色谱(HTNPLC-μRPLC)和全二维液相色谱(HTNPLC×RPLC)系统.样品首先在第一维(CN色谱柱)进行正相分离,第一维洗脱产物选择性地或者交替存储在十通阀上的定量环中,然后切换十通阀将定量环内存储的样品组分转移到第二维(C18色谱柱)进行反相分离.该系统降低了第一维切割组分在第二维柱头的扩散,提高了分离度以及分离效率.采用多环芳烃混合物和天然植物甘草提取液对该二维液相色谱系统进行了评价.

A new method for the analysis of arsenic species in urine by using HPLC-ICP-MS

Gas chromatographic (GC) and liquid chromatographic methods for the investigation of phenylarsenic compounds are presented. With gas chromatography using an electron capture detector (ECD), the chemical warfare agents PFIFFIKUS, CLARK I and CLARK II can be detected. After derivatization with mercaptans and dimercaptans the sum of diphenylarsenic compounds resp. phenylarsenic and phenylarsonic compounds can be detected as the mercapto resp. dimercapto derivatives. High performance liquid chromatography (HPLC) analysis may be used for the detection of triphenylarsenic compounds and ADAMSITE. Received: 17 July 1997 / Accepted: 9 October 1997     

Determination of trimethylsilanol in the environment by LT-GC/ICP-OES and GC-MS

The combination of element-specific investigation by low temperature gas chromatography coupled on-line with inductively coupled plasma optical emission spectroscopy (LT-GC/ICP-OES) and gas chromatography using mass spectrometry detection (GC-MS), as an additional analytical technique for molecular identification, was employed for the determination of volatile organosilicon species. Gaseous and liquid samples from waste deposit sites, waste composting tanks and sewage-disposal plants were investigated. It was frequently possible to identify the labile silanol compound trimethylsilanol as a dominant silicon species in waste disposal and waste composting gases. The results presented give rise to the assumption that trimethylsilanol is a volatile product of the degradation of organosilicon materials under special environmental conditions.

Enantioseparation of four-membered rings by gas chromatography; an overview

The separation of enantiomers by gas chromatography on a chiral stationary phase is stored and conveniently retrieved in the molecular database Chirbase/GC. According to the present information content (version 3/96), a great variety of analytes has been published in several hundred journals. A selected review is given on 364 enantiomer separations of 102 different molecules containing at least one four-membered saturated carbocyclic ring. Factors determining the degree of enantioseparation are outlined and analyzed. Received: 16 November 1996 / Revised: 17 April 1997 / Accepted: 30 April 1997

Recent developments in adsorption liquid chromatography (NP-HPLC) A review

The development of normal phase chromatography mainly in the past ten years is summarized. At first, the difference between normal-phase and reversed-phase chromatography is briefly discussed. According to Snyders theory of retention, some theoretical considerations are added. Most of the stationary phases synthesized in the past years and their field of use in NP-LC are given. They are sorted by linkage to silica and by their polar substituents. The effects resulting from variation of phases and eluents are discussed. Examples for group separation and other applications of NP-LC are given. Received: 10 December 1997 / Revised: 24 February 1998 / Accepted: 26 February 1998

The effects of pH, ionic strength and buffer concentration of mobile phase onR F of acidic compounds in ion-pair TLC

Summary The effects of some factors important in ion-pair, high-performance liquid chromatography were studied in ion-pair, thin-layer chromatography. Tetramethyl and cetyltrimethylammonium salts were used as ion-pairing reagents. As stationary phases, silica gel and chemically bonded reversed-layers (C₁₈) were used. Layers were impregnated with ion-pairing reagent prior to chromatography. In some cases the stationary phase was treated with buffer at different concentrations. The mobile phase contained methanol and water, in one set of experiments buffer, salt for adjustment of ionic strength and ion-pairing reagent were added. The migration behaviour of different benzoic acids was studied. Several problems of ion-pair thin-layer chromatography are discussed. Passed away on 13^th of April, 1998 Presented at: Balaton Symposium on High-Performance Separation Methods, Siófok, Hungary, September 3–5, 1997.     

Determination of small quantities of nitrogen oxides in air by ion chromatography using a chromatomembrane cell for preconcentration

Chromatomembrane (CM) cells operate in computer-aided FIA systems as unique manifolds for extraction and preconcentration procedures. By coupling with ion chromatography an instrumentation was obtained allowing sample preparation and detection of nitrogen oxides in air in a quick and automated way. The aim of this paper is to study the absorption of acid components from air inside the new devices. Received: 11 September 1997 / Revised: 12 November 1997 / Accepted: 16 November 1997
