Vendor selection problem, application

Application of Available Energy Methodology to Vendor Selection Problem... 

As with any process analytical application, instrument selection is based on the required analytical merits (sensitivity, dynamic range, precision and accuracy, etc.), process and enviromnental conditions, integration complexities (mechanical and controls automation) and operational and maintenance requirements. Because of the wide disparity in analytical performance and functionalities among photometric and spectroscopic LIE process instruments, selection should be carefully weighed on the basis of the technical problem, instrumental cost, implementation complexities, ease of use, conunercial and legacy maturity, level of vendor support and cost of ownership. 

Although, as reviewed in other publications (Section 13.1) and made available by vendors (Section 15.1) in their brochures and newsletters, certain characteristic relationships have been developed for most agglomeration methods and performance factors can be collected in charts for the pre-selection of methods, which are most probably suitable for a particular application (Chapter 9 and [B.48, B.97]), determination of the actual design parameters remains a serious problem. 

There is an extremely large selection of these specialized sample introduction techniques, so it is critical that you talk to the vendors so they can suggest the best solution for your application problem. They may not be required for the majority of your application work, but there is no question they can be very beneficial for analyzing certain types of sample matrices and for elements that might be prone to solvent-based spectral overlaps.
