    Notes: Abstract  The National Analytical Reference Laboratory (NARL) was established by the Commonwealth Government within the Australian Government Analytical Laboratories (AGAL) Public Interest Programme in 1997, to help provide Australian scientists with the chemical standards they need to make reliable measurements. Reliable chemical measurements are vital to many aspects of our social and economic life including public health, environmental control, industrial productivity, trade innovation and government regulation. Mutual recognition of measurement results and the avoidance of costly disputes require the development of a structured and common system of measurement. Working-level measurements should be directly linked to national standards, which are themselves interlinked through international comparisons. Although metrology in chemistry is still in its infancy, increasing numbers of countries are establishing facilities to serve both national needs and to contribute to the international measurement system. The aim at NARL is to lead the development of an Australian chemical measurement system, which is harmonized with similar systems in other countries. This paper was presented at the Co-operation on Traceability in Analytical Chemistry (CITAC) symposium on Analytical Quality Assurance for the Twenty-first Century, held in Sydney on 15–16 October 1998. It describes the rationale for establishing NARL, the process of getting it started, the positioning, aims and strategy of NARL, the development of its work programme and plans for both national and international collaboration.

    Notes: Abstract  The UK Valid Analytical Measurement Programme has pump-primed developments in chemical metrology, through a major project on reference methodology and reference materials. This paper provides an overview of developments during 1994–1997 and covers work on primary methods for trace inorganic and trace organic analysis, including the use of isotope dilution mass spectrometry; studies of sample pre-treatment, including digestion, extraction, and separation aimed at improving this weak link in the traceability chain; prioritisation, production and marketing of both pure substance and matrix reference materials; and international collaboration concerned with interlaboratory comparisons and the development of concepts, terminology and systems to underpin the international chemical measurement system. References are given to a number of papers covering specific parts of the programme.

    Notes: Abstract  The paper (Parts I and II) reports the results of a survey carried out to assess the current situation in the field of metrology in chemistry within Europe and to identify future needs for work at the European level. Responses to a questionnaire covering 17 economic sectors and distributed to 17 countries plus the European Commission Joint Research Centre (EC JRC), together with input from a project group, EURACHEM and EUROMET provided the basis of the study. The questionnaire responses clearly indicated that only a minority of countries had clearly defined responsibilities for policy, funding and technical leadership. Similarly only a small number of countries was able to provide any information about levels of funding. Nonetheless, a variety of work is in progress and in some countries the effort is considerable. In other countries discussion is in progress and /or work is beginning. Part I covers the protocol for the study and reports current activities. Part II reports suggestions for future work, a strategy for metrology in chemistry and recommendations for the EC Fifth Framework Programme.

    Notes: Summary The separation in 6 minutes of the sixteen US Environmental Protection Agency (EPA) polycyclic aromatic hydrocarbons (PAHs) on a single packed column by supercritical fluid chromatography (SFC) is described and compared to that obtained using liquid chromatography with the same column. Several environmental samples containing polycyclic aromatic hydrocarbons obtained from various sources including soil, water, petrochemicals and coal have been analysed by SFC under optimised conditions. Packed column SFC is shown to be an efficient and promising method for the rapid monitoring of environmental polycyclic aromatic hydrocarbons.

    Notes: Summary The kinematic viscosity of the slurry used for the packing of microbore columns for liquid chromatography has been correlated with the packing efficiency. The columns were packed into polyetheretherketone (PEEK) tubing with an internal diameter of 0.5 mm using unbonded and bonded spherical silica gels under constant pressure conditions. Higher efficiencies were obtained using slurries suspended in aqueous solutions of surfactants, such as polyoxyethylene sorbitane monolaurte (Tween-20) and sodium dodecyl sulphate, in comparison with organic solvents usually used for column packing. The concentration dependencies of the relative kinematic viscosities of six slurries were compared using capillary viscometry. The slurries with low relative viscosities possessed rheological properties which enabled high packing densities, typical of a stable dense random packing arrangement, to be obtained at moderate packing pressures. The unusually low relative viscosities are discussed in terms of a “porous hydrodynamic bearing” model. The techniques used should also be generally applicable to the slurry packing of conventional columns.
