Applications of gas chromatography in the paint and allied industries. Part 6: Whole paint analysis
Abstract
The examination and identification of solvents and binder resins in particular has been discussed in detail previously. It is the sole purpose of this section to indicate the means available for obtaining these substances from finished paints in such a way as to facilitate their analysis. For example, the ASTM (15) has published a standard procedure for examining the solvent portion of paints by direct injection on to a GC. In this case, so as to prevent blockage of the column by the resin and pigment components, the sample was injected either via a glass injection port sleeve or on to a glass wool plug positioned in the heated injection port. Hence solvent analysis could be carried out without the need to apply any preliminary separation procedures. If however, both solvent and binder resin are to be examined then a procedure for separating these constituents must be applied.
