Guideline‐Directed Medical Therapy After Hospitalization for Acute Heart Failure: Insights From the CONNECT‐HF

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Significant gap remains in the implementation of guideline‐directed medical therapy (GDMT) in patients with heart failure after a hospitalization. We aimed to evaluate the use and titration of GDMT at discharge and over a 12‐month period after

Dynamic behaviour of ISFET-based sensor-actuator systems [PDF]

open access: yes, 1990
Rapid acid-base titrations can be performed at the surface of a noble-metal electrode with coulometrically generated ions. An ISFET is used as an indicator electrode to detect the equivalence point in the resulting titration curve.

Historical remarks on the Henderson-Hasselbalch equation: its advantages and limitations and a novel approach for exact pH calculation in buffer region

open access: yesReviews in Analytical Chemistry, 2012
The theoretical titration curve of a weak acid with a strong base was considered. The limitation of the Henderson-Hasselbalch equation for the calculation of pH in the buffer region was discussed. One novel simple equation for the exact calculation of pH

The titrating conditions in the potentiometric titration of zinc

open access: yesBUNSEKI KAGAKU, 1964
硫酸酸性におけるフェロシアン化カリウムによる亜鉛の定量を,さまざまな滴定条件のもとに,白金-タングステン双金属電極を用いて電位差滴定を行ない,滴定に及ぼす諸影響を検討した.20℃では硫酸濃度,硫酸アンモニウム濃度によって終点の滴定量が異なるが,滴定溶液の容積100mlあたり硫酸濃度範囲0~0.05N,硫酸アンモニウム20gで一定の滴定速度のもとに行なうと,終点までの滴定量の再現性および電位差滴定曲線がともに良好で,終点における電位差変化が大きい.亜鉛濃度0.0025~0.0125Mの溶液を,滴定誤差約+1.5%で定量することができる.60℃ではすみやかに終点に達し,硫酸濃度,硫酸アンモニウム濃度,滴定時間の影響はより小さくなるが,終点における電位差変化が小さい.滴定誤差は約-1.2%である.
