Preferred Label : instantaneous sampling;
Detailed label : instantaneous (spot) sampling in atmospheric chemistry;
IUPAC definition : Obtaining a sample of the atmosphere in a period which is short compared with the
duration of the sampling exercise. Such samples are often called 'grab' samples, a
term not recommended. These are useful for the analysis of hydrocarbons and other
complicated mixtures of trace gases which are relatively stable in a stainless steel
canister or tank and can be transported back to the laboratory for chromatographic
or other analysis which cannot be done satisfactorily in the field.;
