[Determination of serum iron; a comparison of two methods: atomic absorption and bathophenanthroline without deproteinisation (author's transl)].

UNLABELLED: Two methods for the assay of serum iron are compared; determination by atomic absorption after deproteinisation, and spectrophotometric determination after liberation of the iron by a detergent, reduction with dithionite, and chelation with bathophenanthroline disulfonate, without deproteinisation. RESULTS: Regression: y = 0.996 x --0.41 (s: atomic absorption; y: bathophenanthroline method; mumol/1 Fe; r = 0.986. Precision (CV) for a series of identical samples with 14.3 mumol/1: 2.0% for atomic absorption and 1.3% for bathophenanthroline.

Photometric determination of nitrogen. Wet incineration followed by formation of indophenol blue with salicylate/hypochlorite.

Ammonia in wet incineration residues has been analyzed photometrically by a modified Berthelot reaction using a water-free digestion mixture. Phenol is substituted by salicylate in the dye-producing reaction. The method can be adapted for any biological material with a minimum content of 0.04 mug N/sample. Nonprotein nitrogen may be determined in the supernatant of TCA precipitates.
