The development of ion-selective microelectrodes for monitoring lithium ions in blood or serum is very important in the field of clinical chemistry. For this interest, all-solid-state microsensors based on impedance measurement for the detection of Li+ has been developed. The selective PVC membrane composition used was obtained by dissolving 1.2 % (w/w) Lithium ionophore III, 66 % (w/w) o-nitro...

BACKGROUND Cefazolin is a semisynthetic penicillin derivative with a narrow spectrum of activity covering some gram-positive organisms and a few gram-negative aerobic bacteria. OBJECTIVE To determine the physical and chemical stability of cefazolin sodium reconstituted with sterile water for injection and stored in polypropylene syringes or diluted with either 5% dextrose in water (D5W) or 0....

In this work, the critical diameter for detonation was measured for Nitromethane (NM) sensitized with two different amines: Diethylenetriamine (DETA) and Triethylamine (TEA). The critical diameter in glass and polyvinylchloride tubes is found to decrease rapidly as the amount of sensitizer is increased, then increase past a critical amount of sensitizer. Thus the critical diameter reaches a min...

The goal of the current study is to investigate the compatibility of compounded medication with SyrSpend ® SF in nasogastric tubes compared to Nexium® granules and omeprazole Sandoz ® . As a worst case scenario, high doses of paracetamol (acetaminophen) and (es)omeprazole were examined in the smallest available nasogastric tubes. During the study, the three most commonly used materials in nasog...

Soybean oils were packaged in polyvinylchloride, acrylonitrile, clear glass and amber glass bottles and their flavor stabilities were evaluated by a trained sensory panel. Hydrogenated and unhyrdogenated oils showed similar patterns of flavor deterioration regardless of container or type of aging. In accelerated light-exposure tests with air in the headspace, oils in plastic bottles showed flav...
