9、bined and the solvents evaporated just to dryness.The residueis redissolved in a measured quantity of chloroform and thesample split for gravimetric or other analyses,such as HPLC orIR.For the gravimetric determination,a measured portion ofthe sample is filtered and evaporated and the residue weighe
10、d.For other analyses,the remainder of the sample is evaporatedand may be reconstituted in dimethylacetamide prior to injec-tion(see Test Method F1349 for quantitation of UV-absorbingnonvolatiles by HPLC),or treated appropriately prior toexamination by other chromatographic or spectroscopic meth-ods.
11、5.Significance and Use5.1 This test method was developed to measure non-UV-absorbing nonvolatile extractables that may be present andmigrate from a microwave susceptor material during use.Itmay be a useful procedure to assist in minimizing the amountof non-UV-absorbing nonvolatile extractables eithe
