Simultaneous titrimetric determination of bicarbonate and titratable acid of urine.
An acid-titration method for the determination of bicarljonate and titratable acid in the one sample of urine is described. The method needs only one manipulation of the sample of urine, and was devised to simplify routine laboratory methodology. The accuracy and precision of the urinary bicarbonate method during routine laboratory use is comparable to that obtained by using the Van Slyke manom...
متن کاملDetermination of hydrogen ion concentrations in phosphate and borate mixtures by means of the quinhydrone electrodes.
THE application of the quinhydrone electrode (or the quinoquinhydrone electrode or the hydroquinhydrone electrode) as substitute for the hydrogen electrode for the determination of PH is based on the fact that the values of the potentials between one of these electrodes and the hydrogen electrode vary but very little if the electrolytes of the two electrodes of the chain examined are identical....
متن کاملA hydrogen catheter electrode for the determination of blood flow through organ tissue and coronary blood flow under continuous hypoxia.
In order to develop an applicable H2 Pt electrode for the determination of average blood flow through organs, a catheter tip electrode covered with a Teflon membrane was designed. The properties of the covered electrode were studied polarographically mainly with reference to the effects of the applied voltage on the linearity, reproducibility and response time of the H2 current against PH2. Nex...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولDetermination of Phenylalanine in Blood and Urine.
A modification is described of the method of LaDu and Michael for estimating the concentration of L-phenylalanine and L-tyrosine in the blood by oxidation with L-amino acid oxidase. The proteins of serum or plasma are removed in an ultrafiltration step that greatly reduces the nonspecific absorption, increasing the sensitivity and precision of the method. The ultrafiltrate is added to a composi...
