Typical cells different moisture

All of the sanples were treated by one of three different standard procedures for vacuum/pressure inpregnation Full Cell Method, Enpty Cell Method (Lowry) or modified Full Cell Method (15). The treatments were applied in a modified pressurized paint tank set up to simulate the procedures used commercially in typical pressure treating cylinders. It was connected to a letboratory vacuum pump in order to pull a vacuum of up to 29 in. Hg (98 kPa), and a conpressed air cylinder in order to provide up to 120 psi (827 kPa) air pressure. After treatment, the surface of specimens was wiped free of excess solutions, the sanples were air dried overnight, then placed in the circulating air oven and dried to constant weight to remove solvent and moisture before calculating retentions.
