Chromium Deficiency During Total Parenteral Nutrition

JAMA: The Journal of the American Medical Association, 1979
Chromium is required for maintenance of normal glucose tolerance. After complete bowel resection and five months of total parenteral nutrition, severe glucose intolerance, weight loss, and a metabolic encephalopathylike confusional state developed in a patient. Serum chromium levels were at the lowest normal level. Supplementation of 150 μg of chromium

Excessive chromium intake in children receiving total parenteral nutrition

The Lancet, 1992
Various expert bodies have recommended that the daily parental intake of chromium in children receiving total parenteral nutrition (TPN) should be 0.20 micrograms/kg. To test whether this recommendation is appropriate, we assessed chromium intake, serum chromium concentrations, and renal function in 15 children receiving TPN. The median duration of TPN

Determination of chromium(III), chromium(VI) and total chromium in chromate and trivalent chromium conversion coatings by electrospray ionization mass spectrometry

Talanta, 2012
Developed were the determination methods of Cr(VI) and Cr(III) by electrospray ionization mass spectrometry, where HCrO(4)(-) (m/z 117) and [Cr(III)(cydta)](-) (m/z 394) were measured, respectively. Moreover, total Cr was also determined by measuring [Cr(III)(cydta)](-) after reduction of Cr(VI) with ascorbic acid.

Determination of chromium(III) and total chromium using dual channels on glass chip with chemiluminescence detection

Talanta, 2007
A simple, rapid and sensitive method for the determination of chromium(III) and total chromium using the simple dual T channels on glass chip with negative pressure pumping system and chemiluminescence (CL) detection is presented. The CL reaction was based on luminol oxidation by hydrogen peroxide in basic aqueous solution catalyzed by chromium(III ...

Determination of chromium(III) and total chromium in marine waters

Analytical and Bioanalytical Chemistry, 1996
The development of an analytical technique is described which may be used to determine chromium, chromium(III) and chromium(VI) in estuarine and coastal waters. The method is based on selective micro-solvent extraction with subsequent GFAAS. The technique has been applied in a major North Sea estuary.

Chromium Content of Total Parenteral Nutrition Solutions

Journal of Parenteral and Enteral Nutrition, 1990
Chromium (Cr) present as contaminant was analyzed by flameless atomic absorption spectrometry in a variety of commercially produced solutions and additives commonly used in total parenteral nutrition (TPN) formulas. Total Cr likely to be administered unintentionally per day was estimated both by summing the Cr in appropriate volumes of each solution ...

Quantification of total chromium and hexavalent chromium in UHT milk by ETAAS

The Analyst, 1998
Procedures for the quantification of total chromium and hexavalent chromium in UHT milk samples are presented. Total chromium was determined directly in milk with the addition of a surfactant and a mixture of Pd and Mg as a chemical modifier. For the selective separation of hexavalent chromium, the sample pre-treatment consisted in precipitation of ...
