QUANTITATIVE ANALYSIS 



developed applications of the ammonia procedures. VVinnick (42) 

 applied the diffusion apparatus to the determination of: alcohol, 

 with chromic acid in the inner chamber; lactic acid, which was oxi- 

 dized in the outer chamber to acetaldehyde, the latter diffusing to a 

 bisulfite solution in the inner chamber; acetone, which diffused to 

 bisulfite; threonine, which was oxidized by periodate to acetaldehyde 

 in the outer chamber, with diffusion of the aldehyde to bisulfite.
