A NEW MICRO COLORIMETRIC METHOD FOR THE DETERMINATION OF TRYPTOPHANE

A Colorimetric Micro-method for the Determination of Glutathione.

1. A rapid colorimetric and apparently specific micromethod for the determination of total glutathione in small amounts of tissue is described. Generally, less than 30mg. of tissue is sufficient and this is homogenized in ice-cold 3% metaphosphoric acid. The product is filtered through sintered glass and neutralized or diluted before being added to a cuvette containing phosphate buffer, pH7.1, ...

New Enzymatic Colorimetric Method for the Quantitative Determination of Phenylalanine in Dry-Blood Spots

Phenylketonuria (PKU) is an autosomal recessive disorder, which is characterized by severe mental retardation, microcephaly and seizures. The symptoms of this disease can be prevented if detected soon after birth. Therefore, blood Phenylalanine (Phe) measurement is essential for the early diagnosis, treatment and dietary monitoring of PKU patients. The goal of this research was to introduce a r...

A new simple semimicro method for colorimetric determination of urea.

A colorimetric micro-method for the determination of glycogen in tissues.

A New Method for Hybrid Energy Storage Capacity Determination in Isolated Micro Grid

In recent years, hybrid energy storage (HES) to increase lifetime and reliability extremely are used in renewable systems and microgrids. In this paper, a new method for determining battery and supercapacitor capacity in an isolated microgrid is presented. Difference between Generation and load power using discrete fourier transform is transferred to the frequency domain and by determining the ...
