The aluminium absorbs the radiation, heats up and transfers the heat to xenon gas contained in the cell. As the temperature of the gas varies the curvature of a flexible mirror of antimony-coated collodion, forming a part of the cell, changes. Reflection of a light beam from this mirror, which is on the outside of the Golay cell, indicates its curvature and therefore the intensity of radiation absorbed by the cell. 

To prepare a gelatinous expl, mix with stirring 4 pts of collodion cotton dissolved in 10 pts of acet, 6 pts of nitrated glue , and 1 pt of castor oil (to increase the flexibility of the product). After evapg the acet, the mass can be cartridged To prepare a granular expl, the above procedure is used, except that the castor oil is replaced by an equal wt of mononitronaphthalene. About 80% of the acet is evapd, and the mass extruded in any desired shape. Or, the acet can be almost completely removed, and the mass rolled into sheets which can be cut to any desired size... 

Collodions These are the fluid preparation intended for external use. The vehicle of collodion are volatile (e.g. ethyl alcohol) in nature and when applied on the skin (with brush or rod) evaporates to the skin and leaving a flexible, protective film. The film producing agent is pyroxylin (nitrocellulose) and for flexibility colour oil is added.

Collodions are preparations of cellulose nitrate (pyroxylin) dissolved in an organic solvent. The solvent evaporates rapidly and the resultant flexible film is used to hold a medicament, e.g. salicylic add, in contact with the skin. They are irritant and inflammable and are used to treat only small areas of skin. 

Paints and liquids contain 11-17% salicylic acid, often in a collodion-based vehicle. Collodions contain pyroxylin, a nitrocellulose derivative, dissolved in a volatile solvent such as ether, acetone or alcohol. On application, the solvent evaporates, leaving on the skin an adherent, flexible, water-repellent film containing the medicament. This has the advantage of maintaining the salicylic acid at the site of application and also assists skin maceration by preventing moisture evaporation. Liquid preparations are usually applied daily for several days until the corn or callus can be easily removed.

Improved membranes have been the key to recent advances in ultrafiltration. The finest niter papers have pore diameters of as small as 1000 nm (1 micron) whereas ultrafilter membranes can be made with pore diameters from 1000 nm to as small as 2-3 nm. For many years cellophane or freshly formed films from collodion (nitrocellulose) were used, but now a number of manufacturers supply strong, flexible, and durable membranes of remarkably uniform pore size yet with high porosity, permitting rapid flow of water. Porous glass membranes have also been developed as well as porous carbon. Po rous ceramic with a microporous coating provides an ultrafilter highly resistant to high temperature and chemical attack. 

Collodion of Salicylic Acid, B.P.C, Contains 12 per cent of salicylic acid dissolved in flexible collodion. The salicylic acid can be determined by direct titration 2 ml is washed out from a pipette with a mixture of three parts of ether and one part of ethanol, previously neutralised to phenol red, and titrated directly with O-IN sodium hydroxide to this indicator. 1 ml = 0 01381 g.
