Figure 6c shows the effect of etching this specimen with alkaline sodium picrate
, which colors the large cementite brown.

1886 - Jaffe develops alkaline picrate
method for the determination of creatinine; The Pasteur Institute is founded in Paris.
Serum creatinine was measured by use of an alkaline picrate
method (Boehringer) on an automated Hitachi 747 analyzer using reagents on a fasting blood sample at the time of survey, 1994-95.
Creatinine estimation employed the reaction of creatinine and sodium picrate
to form creatinine picrate
, yellow needles from ethanol, melted at 203-204[degrees]C Anal.
The contract is to develop and demonstrate a mobile system capable of producing higher order commercial products from ammonium picrate
Urine creatinine was measured at the laboratory of the National Institute of Diabetes and Digestive and Kidney Diseases Epidemiology and Clinical Research Branch (Phoenix, AZ, USA) by an automated alkaline picrate
methodology run on a rapid flow analyzer (Lee et al.
Before GFR measurement, we collected a 5-mL blood sample for serum creatinine measurement using an alkaline picrate
rate-blanked compensated kinetic assay (Roche Modular analyzer; Roche Diagnostics) with calibration traceable to IDMS.
Creatinine level in serum was estimated by the alkaline picrate
method, using a creatinine kit (Varley and Alan, 1984).
These efforts highlighted limitations of commercially available methods for creatinine measurement as well as the differences in results among methods resulting from a lack of assay standardization and the nonspecificity of the alkaline picrate
method used in the majority of clinical laboratories (3, 7, 8).
Plasma and urine sodium, potassium and lithium concentrations were measured by flame photometry, while creatinine was determined spectrophotometrically using alkaline picrate
