    Data correlation in on-line solid-phase extraction-gas chromatography-atomic emission/mass spectrometric detection of unknown microcontaminants (1998)
    Springer
    Chromatographia 48 (1998), S. 273-283

    Notes: Summary A procedure is described for the (non-target) screening of hetero-atom-containing compounds in tap and waste water by correlating data obtained by gas chromatography (GC) using atomic emission (AED) and mass selective (MS) detection. Solid-phase extraction (SPE) was coupled on-line to both GC systems to enable the determination of microcontaminants at the 0.02–1 μg L−1 level in 7–50 mL of aqueous sample. The screening was limited to compounds present in at least one heteroatom-selective GC-AED trace above a predetermined concentration level. These compounds were identified by their partial formulae (AED) and the corresponding mass spectra, which were obtained from the GC-MS chromatogram via the retention index concept. The potential of the approach was demonstrated by the identification of target compounds as well as all unknowns present in tap and waste water above the predetermined threshold of 0.05 μg L−1 (tap water) or 0.5 μg L−1 (waste water).

    On-line coupling of solid-phase extraction and gas chromatography with atomic emission detection for analysis of trace pollutants in aqueous samples (1995)
    Springer
    Chromatographia 40 (1995), S. 119-124 
    Details
    ISSN: 1612-1112
    Keywords: Gas chromatography ; Atomic emission detection ; Aqueous samples ; Solid-phase extraction ; Organophosphorus pesticides

    Topics: Chemistry and Pharmacology
    Notes: Summary An on-line, solid-phase extraction gas chromatography atomic-emission detection (SPE-GC-AED) system has been set up using an on-column interface to transfer 100 μl of desorbing solvent to the GC part of the system. Analytical characteristics such as recovery, precision and linearity of calibration plots were comparable with those of the off-line combination of SPE-GC-AED using organophosphorus pesticides as test compounds. The fully on-line set-up causes a marked improvement in detection because of the quantitative transfer of the analytes from the SPE module to the GC: detection limits are as low as 5–20 ng l−1 for the analysis of 10 ml raw and spiked surface water samples using the phosphorus channel. Detection levels can be further enhanced by processing up to 100 ml samples. The integrated analytical system is robust. The potential of the on-line set up has been demonstrated for the analysis of surface water and waste water.

    APOM-project: a survey of pharmacy organization and management (1998)
    Springer
    Pharmacy world & science 20 (1998), S. 248-252

    ISSN: 1573-739X
    Keywords: Community pharmacy ; Management ; Organization structure ; Pharmacy organization ; Strategy ; Working organization

    Notes: Abstract In 1994, a Ph.D-study started regarding pharmacy, organization and management (APOM) in the Netherlands. The APOM-project deals with the structuring and steering of pharmacy organization. This article describes the summary of the empirical results of a survey in a relatively large sample (n = 169). Generalization to the population of pharmacies in the Netherlands was made. Thought results comprised a total number of seven clusters of priorities of pharmacy mixes. Most pharmacy managers were observed with product and customer activities in the first position; pharmaceutical and customer activities were perceived as the most important. Action results comprised a total number of five clusters of activities of pharmacy mixes. Most pharmacy managers were observed with product and process activities in the first position; pharmaceutical and process activities were performed most frequently. The results showed that the traditional conception of the work in the community pharmacy is still vividly present.

    APOM‐project: managing change to the customer in community pharmacy practice (1999)

    Notes: Abstract In 1994, a Ph.D.‐study started regarding pharmacy, organization and management (APOM) in the Netherlands. This article describes the final phase of the study in community pharmacy practice: managerial problems in change to the customer and the difference between supported pharmacy managers and independent ones. It appeared that pharmacy managers experienced problems with the formulation and use of aims, norms, and measurements. Although many organizations operating in the pharmaceutical sector are a good source for new ideas, they lack to have the proper support for these problems. The difference between supported and independent pharmacy managers was minimal in the change to the customer. Pharmacy managers are in need of micro‐instrumentalization: aims, norms, and monitor instruments for customer activities applicable at their own pharmacy. Moreover, pharmacy managers will have to learn how to deal with the tension between money and care in order to improve the 'grip' on their organization.

    On-line solid-phase extraction-gas chromatography-ion trap tandem mass spectrometric detection for the nanogram per liter analysis of trace pollutants in aqueous samples (1997)
    Springer

    Notes: Summary On-line solid-phase extraction-gas chromatographyion-trap tandem mass spectrometry (SPE-GC-MS/MS) has been used for the trace-level determination of polar and apolar pesticides. The SPE-GC interface, an Autoloop 2000, was operated at an injection temperature of 90°C which permitted the determination of thermolabile pesticides such as carbofuran and carbaryl. Rectilinear calibration curves were obtained for the analytes tested over a range of 0.1–500 ng L−1, using a sample volume of 10–100 mL for enrichment on an SPE cartridge packed with styrene-divinylbenzene copolymer. The detection limits for the pesticides were in the 0.01–4 ng L−1 range. For a number of pesticides acceptable tandem mass spectra were obtained at levels as low as 0.1 ng L−1 level in real-life water samples. As a demonstration of the applicability of this technique for inorganic anions, bromide and nitrite were converted into 4-bromoacetanilide and 2-phenylphenol, respectively. The reaction products were pooled and subjected to simultaneous analysis by the present method using full-scan mass spectrometric detection. The detection limits were 0.3 and 2 ng L−1, respectively.
