• ###### Specific Gravity Determination - Impact Analytical

Services Specific Gravity Determination. Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance.

• ###### METHODS FOR THE DETERMINATION OF SPECIFIC GRAVITY

Specific Gravity is formally defined as the ratio of gas density to air density when both are at standard conditions of 0 Degree C and 760 mm Hg. Over the years the definition evolved to become the ratio of gas density to air density at the same temperature and pressure, Relative to each other.
