INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES( separating components of materials in general B01D, B01J, B03, B07; apparatus fully provided for in a single other subclass, see the relevant subclass e.g. B01L; measuring or testing processes other than immunoassay, involving enzymes or micro-organisms C12M, C12Q; investigation of foundation soil in situ E02D 1/00 ; sensing humidity changes for compensating measurements of other variables or for compensating readings of instruments for variations in humidity, see G01D or the relevant subclass for the variable measured; testing or determining the properties of structures G01M; measuring or investigating electric or magnetic properties of materials G01R; systems or methods in general, using reception or emission of radiowaves or other waves and based on propagation effects, e.g. Doppler effect, propagation time, direction of propagation, G01S; determining sensivity, graininess, or density of photographic materials G03C 5/02 ; testing component parts of nuclear reactors G21C 17/00 ;
{
controlling or regulating non-electric variables G05D; measuring degree of ionisation of ionised gases, i.e. plasma H05H 1/0006 ; testing electrographic developer properties G03G 15/0848
}
)
NOTE
-
In this subclass, the following terms are used with the meanings indicated :
- "investigating" means testing or determining;
- "materials" includes solid, liquid or gaseous media, e.g. the atmosphere.

Attention is drawn to the Notes following the title of class G01.

Inventions relating to investigating the properties of materials, specially adapted for use in processes covered by subclass B23K, are classified in group B23K 31/12 .
