The feature-packed Integra XL is a compact sequential ICP which delivers more features, more power and flexibility and greater performance than higher priced competitive systems. The radially-viewed instrument provides detection limits which closely match and for many elements, out-perform those of axially viewed systems in real samples, with all the benefits of a radially viewed system, offering higher sensitivity, greater freedom from chemical and background interferences, minimal ionisation effects and greater dynamic range.
The Integra XL is suitable for a broad range of applications. However, there are a number of application areas which require the minimization of ionisation effects, freedom from chemical and background interferences, wide dynamic range and high sensitivity where the Integra will excel. These include the following application areas:
Agriculture. In particular soil and plant samples, where there can be a significant ionisation effects due to major constituents of the sample, e.g., Ca, and high sensitivity is required for trace element analysis.
Organics and Petrochemical. Organic samples generally have high background levels and as such are unsuitable for axial viewing. A majority of the analyses require high sensitivity and can include applications such as P in edible oils, quality control of lube oils and Pb in unleaded gasoline.
Biological. Blood, serum, urine and tissue samples where there can be significant matrix effects which restrict the capability of an axial system, but high sensitivity is required for essential trace elements or toxic trace elements.
Geological. Generally involves the analysis of samples with high total dissolved solids, which are more suited to a radially viewed system. This can include analyses such as trace elements in silicate and phosphate rocks or the analysis of rare earth elements which requires not only high sensitivity but also high spectral resolution.
Food and Beverages. This includes sample types such as milk and dairy products where high sensitivity is required for trace analysis and the high Ca levels will cause strong ionisation effects.
The Integra XL also provides outstanding instrument performance in key areas such as:
Automated instrument optimisation. Traditionally a difficulty with ICP because of the interdependence of critical instrument parameters, Integra XL provides a powerful auto-optimisation routine which means that even inexperienced operators can obtain fast and accurate results. Complete computer control of all instrument parameters also allows for accurate diagnostic routines which can alert the user to potential difficulties before they cause problems.
Analysis of difficult matrices (slurries/high salt samples/milk powders/solvents) without time-consuming sample preparation. Fast and easy switching from aqueous to organic matrices.
Linked Multiple Applications in conjunction with an autosampler allows unattended operation. The instrument will automatically set parameters for different methods as required.
Highly stable plasma and fully reproducible methods with mass flow gas controls on all three gas flows, and thermostatted optics to provide ultimate stability, even in non-air-conditioned laboratories.
Powerful Windows® based software, providing a multi-tasking environment with point and click simplicity.
