aliquot in analytical chemistry
Known amount of a homogeneous material, assumed to be taken with negligible sampling error.
Note 1: The term is usually applied to fluids.
Note 2: The term “aliquot” is usually used when the fractional part is an exact divisor of the whole; the term “aliquant” has been used when the fractional part is not an exact divisor of the whole (e.g., a 15 mL portion is an aliquant of 100 mL).
Note 3: When an aliquot is taken of a laboratory sample or test sample or the sample is otherwise subdivided, the samples have been called split samples.
