Definitions and units Clause Samples
The 'Definitions and units' clause establishes the precise meanings of key terms and specifies the measurement units used throughout the contract. It typically lists important words or phrases and assigns them clear definitions, while also standardizing units such as meters, kilograms, or currency to avoid ambiguity. By doing so, this clause ensures that all parties interpret the contract language consistently, reducing the risk of misunderstandings or disputes over terminology or measurements.
Definitions and units. (i) The ‘‘cation exchange capacity’’ (CEC) is the sum total of exchangeable cations that a sediment or soil can adsorb. The CEC is expressed in milliequivalents of negative charge per 100 grams (meq/ 100g) or milliequivalents of negative charge per gram (meq/g) of soil or sedi- ment.
Definitions and units. (i) ‘‘Hydrol- ysis’’ is defined as the reaction of an organic chemical with water, such that one or more bonds are broken and the reaction products of the trans- formation incorporate the elements of water (H2O).
Definitions and units. The UV-VIS absorption spectrum of a solution is a function of the concentration, c1, ex- pressed in mol/L, of all absorbing spe- cies present; the path length, d, of the spectrophotometer cell, expressed in cm; and the molar absorption (extinc- tion) coefficient,ei, of each species. The absorbance (optical density) A of the solution is then given by: A = d∑εici i For a resolvable absorbance peak, the band width λ is the wavelength range, expressed in nm=10¥9 m, of the peak at half the absorbance maximum.
Definitions and units. (i) ‘‘Desorption efficiency’’ of a particular compound applied to a sorbent and sub- sequently extracted with a solvent is the weight of the compound which can be recovered from the sorbent divided by the weight of the compound origi- ▇▇▇▇▇ sorbed.

Definitions and units. (i) ‘‘Desorp- tion efficiency’’ of a particular com- pound applied to a sorbent and subse- quently extracted with a solvent is the weight of the compound which can be recovered from the sorbent divided by the weight of the compound originally sorbed.
