Summary of Test Method 4. Condensed solvent and water are continuously separated in a trap, the water settling in the graduated section of the trap and the solvent returning to the still.

Percent may be determined by mass or by volume.

The blank shall be determined to the nearest scale division and used to correct the volume of water in the trap in Section The still, trap, and condenser may be connected by any suitable method that produces a leakproof joint. Preferred connections aastm ground joints for glass and O-rings for metal to glass.

Typical awtm are illustrated in Fig. The stills and traps should be chosen to cover the range of materials and water contents expected. On assembly, care shall be taken to prevent the joints from freezing or sticking. Always apply a very thin?

Vessels of, and mL nominal capacity have proved satisfactory. A gas ring burner with ports on the inside circumference shall be used with the metal still. The gas ring burner shall be of such dimensions that it may be moved up and down the vessel when testing materials that are likely to foam or solidify in the still.

To minimize the problem, all apparatus must be cleaned chemically at least daily to remove surface? More frequent cleaning is recommended if the nature of samples being run causes persistent contamination. Only representative samples obtained as speci? Thereafter, each major subdivision that is, 2. Rinse the material adhering to the cylinder with one mL and two mL portions of the solvent-carrier liquid see Section 6 and Table 1.

Drain the cylinder thoroughly after the sample transfer and each rinsing. In cases of material with a low-water content when large samples must be used, a solvent-carrier liquid volume in excess of mL may be necessary.

If a metal still with a removable cover is used, insert a gasket of heavy paper, moistened with solvent, between the still body and the cover. The condenser tube and trap must be chemically clean to ensure free drainage of water into the bottom of the trap. Insert a loose cotton plug in the top of the condenser to prevent condensation of atmospheric moisture inside it. Circulate cold water through the jacket of the condenser. If the metal still is used, start heating with the ring burner about 76 mm 3 in.

Precision and Bias The precision when using the 2-mL trap or a 5—mL trap has not been established. If there is a persistent ring of water in the condenser tube, carefully increase the rate of distillation or cut off the condenser water for a few minutes.

Dislodge any drops of water adhering to the sides of the trap with a glass or polytetra? Read the volume of the water in the trap to the nearest scale division.
