A Semimicro Modification of the Karr Urea Determination Method Using the Somogyi Serum Filtrate.

B ECAUSE of the pressing need for conserving both the patient’s blood and laboratory time, an attempt has been made to modify the Karr urea method (1) for semimicro amounts of Somogyi filtrate (2). Since this serum filtrate was already being used for glucose in our clinical laboratory, the saving of time and material which such a method would bring-if accurate enough for clinical purposes-was o...

A new colorimetric method for the determination of urea nitrogen in blood with diacetyl monoxime-glucuronolactone-glucosaccharodilactone reagent.

In a previous paper,3) a colorimetric method for the determination of urea nitrogen in blood and urine was presented on the basis of a color reaction of urea with diacetyl monoxime (DAM) in phosphoric acid solution in the presence of D-glucuronolactone (GL), which served to produce a photo-stable color and eliminate the sigmoidal nature of calibration curve observed usually in the DAM method.4)...

An Improved Method for the Simple and Accurate Colorimetric Determination of Urea with Ehrlich's Reagent.

An improved method for the colorimetric determination of urea is described. The method is simple, requiring a deproteinized filtrate obtained after treatment of a small quantity of whole oxalated blood, serum, plasma or urine with 12.5% trichloracetic acid containing 50 g. activated carbon. The addition of Ehrlich's reagent to this filtrate results in the immediate production of a stable yellow...

Colorimetric Determination of Urea by Reginald M. Archibald

The use of a-isonitrosopropiophenone, CS& *CO * CNOH. CH3, as a reagent for the calorimetric determination of urea has been mentioned in a previous communication (1). The present report outlines a simple method for the calorimetric determination of urea in blood filtrates and urine by means of this reagent and compares the values obtained by this method with those given by the urease ((2), (3) ...

Chitosan Capped Silver Nanoparticles as Colorimetric Sensor for the Determination of Iron(III)

A selective, simple and low-cost method for the colorimetric determination of Fe3+ ions based on chitosan capped silver nanoparticles (Chit-AgNPs) was presented. Chitosan is a cationic polyelectrolyte and possesses amino and hydroxy groups which make it widely used as a capping agent for Ag NPs. The synthesized chitosan capped silver nanoparticles with excellent colloidal stability were charact...
