Analysis of Milk Phospholipids by Chromatography and Infrared Spectrophotometry

Analysis for carboxyhemoglobin by gas chromatography and multicomponent spectrophotometry compared.

Measurements of carboxyhemoglobin (HbCO) by gas chromatography (GC) were compared with those obtained by multicomponent spectrophotometric analysis (MCA). Correlation was good for HbCO ranges (proportion of total hemoglobin) of 1.5 to less than or equal to 5% (GC = 0.94 MCA + 0.37%, n = 25, r = 0.98); 5.0 to less than or equal to 10.0% (GC = 0.89 MCA + 0.63%, n = 19, r = 0.93); greater than 10%...

Semiautomated spectrophotometry of total phospholipids in plasma.

A one-stage semiautomated method for estimating total phospholipids in plasma is reported. The phospholipids are extracted into aqueous ethanol, combined with a Lewis acid, and the change in pH is monitored colorimetrically. The method, compared with the acid digestion method of Gomori [J. Lab. Clin. Med. 27, 955 (1942)], gives results that are about 0.25 mmol/liter lower, but seems to be a sui...
