Liquid applied linings application

Most liquid applied lining materials are capable of being formulated to meet requirements for specific applications. Corrosion data referring to the suitability of a lining material for a specific corrodent indicates that a formulation is available to meet these conditions. Since all formulations available may not be suitable, the manufacturer must be checked as to the suitability of his formulation. 

Vibrational spectroscopy, in the form of mid-IR, NIR and Raman spectroscopy has been featured extensively in industrial analyses, both quality control (QC), process monitoring applications and held-portable applications [1-6]. The latter has been aided by the need for advanced instrumentation for homeland security and related HazMat applications. Next to chromatography, it is the most widely purchased classihcation of instrumentation for these measurements and analyses. Spectroscopic methods in general are favored because they are relatively straightforward to apply and to implement, are rapid in terms of providing results, and are often more economical in terms of service, support and maintenance. Furthermore, a single spectrometer or spectral analyzer, in a near-line application, may serve many functions, whereas chromatographs (gas and liquid) tend to be dedicated to only a few methods at best. 

After veneers have been unitized from small strips to full sheets of the desired width, usually 4 feet by 8 feet in softwood plywood and various widths and lengths for hardwood custom manufactured plywood, they are ready to be fed through a glue application which coats one or both sides of veneer sheets with liquid adhesive. These applicators control the amount of adhesive transferred to the veneer. The amount of glue mix applied per 100 square feet of surface area (single glue line basis) will approximate 4-5 pounds and the amount of resin solids 1-1.5 pounds. 

A review of chromatographic methods is beyond the scope of this contribution. Both liquid chromatography (LC) and gas chromatography (GC) have been applied in numerous cases to off-line analyses of biotechnological samples but the on-line application has only recently been developed. The scope of chromatographic methods is the separation of the individual constituents of mixtures as they pass through columns filled with suitable stationary phases (Fig. 20). The... 

Multidimensional HPLC offers very high separation power when compared to monodimensional LC analysis. Thus, it can be applied to the analysis of very complex mixtures. Applications of on-line MD-HPLC have been developed, using various techniques such as heart-cut, on-column concentration or trace enrichment applications in which liquid phases on both columns are miscible and compatible are frequently reported, but the on-line coupling of columns with incompatible mobile phases have also been studied.
