Abstract

The radiant flux (F) transmitted by bandpass interference filters of similar type is approximately proportional to the product of peak transmittance (tp) and half-height bandwidth (Wh). A study of 297 filters of varied design (1-, 2-, 3-cavity), the collections of six vision laboratories, showed that this relation was not accurate across all filters. However, a simple function, incorporating Wh and another bandwidth Wi at a lower transmittance t, predicts F with a precision that is ample (+/- 5%) for most psychophysical research. This function provides a rapid means of calibration. Bandwidth errors caused by 2- and 3-cavity filters are discussed as well as their luminous 'blocking' efficacy.

Simultaneous determination of phthalate di- and monoesters in poly(vinylchloride) products and human saliva by gas chromatography-mass spectrometry.

A gas chromatographic-mass spectrometric (GC-MS) method using selected ion monitoring (SIM) is described for the simultaneous determination of phthalate di- and monoesters in poly(vinylchloride) (PVC) products. The method consists of the following four procedures; (1). liquid-liquid extraction with ethyl acetate from the acidified aqueous homogenates of the PVC products, (2). esterification with trimethylsilyldiazomethane (TMSD) and methanol, (3). clean-up using Florisil column chromatography and (4). quantitative determination of methylated phthalate monoesters by GC-MS using SIM. The methylated monoesters show a characteristic mass fragment pattern at m/z 163, 149 and 91. The calibration curves for the monoesters were linear from 0.05 to 10 ng (injection volume 1 micro l). Overall recoveries ranged from 86.6 to 94.3%. The limits of detections for these methylated derivatives were in the range of 2.0-5.0 ng/g (S/N=3). This method was applied to phthalate monoesters in PVC toy products. Mono-n-butyl phthalate and mono-2-ethylhexyl phthalate were found at levels of 6.42-11.62 micro g/g and 30.50-41.81 micro g/g, respectively. No monoethyl phthalate, mono-n-hexyl phthalate and monobenzyl phthalate were found in the toy products. The method was also applied to these compounds in human saliva.

Liquid chromatography/electrospray ionisation-mass spectrometry method for the quantification of sphingosine and sphinganine in cell cultures exposed to fumonisins.

Fumonisins, mycotoxins produced by Fusarium verticillioides, are potent inhibitors of the de novo sphingolipid biosynthesis via inhibition of the key enzyme ceramide synthase. The cellular response to a fumonisin exposure is obvious as an alteration of the ratio of the sphingoid bases sphingosine (SO) and sphinganine (SA). We developed a new column liquid chromatography/electrospray ionisation-mass spectrometry (LC-ESI-MS) method for the rapid, simultaneous and quantitative determination of these bases in cell cultures of immortalised human kidney epithelial cells (IHKE cells). For sample preparation, cell lysates were only diluted, centrifuged and directly used for LC-MS measurements. Quantification was carried out using phytosphingosine (PSO) as an internal standard. Detecting the protonated molecule [M+H](+) signals of SO (m/z 300) and SA (m/z 302) in the selected ion monitoring (SIM) mode, detection limits of 10 pg for SO (signal-to-noise ratio S/N=3:1) and 25 pg for SA (S/N=3:1) were established. The average recovery for SO and SA was higher than 90% for control IHKE-cells, respectively. The developed LC-ESI-MS method allows the sensitive, selective and rapid monitoring of sphingosine and sphinganine in cell matrices with a drastically reduced time for sample preparation.

Improved sample preparation for the quantitative analysis of paroxetine in human plasma by stable isotope dilution negative ion chemical ionisation gas chromatography-mass spectrometry.

An improved sample work-up and derivatisation procedure for the quantitative determination of paroxetine in human plasma by gas chromatography-negative ion chemical ionisation mass spectrometry is presented. Solvent extraction from plasma samples at alkaline pH was combined with derivatisation to the pentafluorobenzyl carbamate derivative in one step and subsequently analysed without any further purification. Thus, lengthy and time-consuming solvent evaporation steps are avoided to assure high-throughput analysis. Complete validation data are presented. The method is rugged, rapid and robust and has been applied to the batch analysis of paroxetine during pharmacokinetic profiling of the drug.
