The vacuum oven was used by most laboratories in the 1920s and 1930s. The vacuum oven method (AOAC 934.01) was made official in 1934 by establishing the temperature to be between 95-100C and the time to be 5 hours (4). The other official LOD method for feeds is AOAC 930.15 which dries materials at 135C for 2 hours.
