SRTC evaluated the feasibility of using the H Canyon on-line diode array spectrophotometer to measure uranium concentrations in Tank 16.7. On-line measurements will allow an increase in highly enriched uranium (HEU) production by removing delays associated with off-line measurements. The instrument must be able to measure uranium at concentrations below 1.0 g/L with an uncertainty no greater th...

Background and Objectives: The instructions of the manufacturer showed that metronidazole infusion solution (5mg/mL) is incompatible with few drugs. This study aimed to determine the physical and chemical compatibilities of metronidazole infusion with commonly used intravenously administered physiological solutions. Methods: Metronidazole injection in a commercially available concentration of 5...

A convenient way to estimate the number of viable cells growing in microtitre tray wells is to use a colorimetric assay and an automatic microplate scanning spectrophotometer. One such assay, developed by Mosmann, depends on the reduction by living cells of tetrazolium salt, MTT, to form a blue formazan product. However the original technique has several technical limitations, namely a less tha...
