Quantitative determination of Ibuprofen by chemiluminescent method

Electrogenerated chemiluminescent determination of oxalate.

Determination of okadaic acid in shellfish by using a novel chemiluminescent enzyme-linked immunosorbent assay method.

A direct competitive chemiluminescent enzyme-linked immunosorbent assay (CL-ELISA) was developed to determine okadaic acid (OA). Concentrations of the capture monoclonal anti-OA antibodies, conjugate of OA-HRP and a composition of blocking buffers were varied to optimize the assay condition. The values of IC10, IC50 and working range (IC20-IC80) for CL-ELISA were 0.01, 0.07, and 0.03-0.2 ng/mL,...

multiwavelength pectrophotometric determination of stability constants of 4-(2– thiazolylazo) resorcinol (tar) with la3+, y3+ and th4+ in organic-water mixed solvents by chemometrics method & simultaneous spectrophotometric determination of lead, copper and nickel using xylenol orange by partial least squares calibration method

تشکیل کمپلکس های tarبا یون های لانتانیم, ایتریم و توریم در دمای 25 درجه، قدرت یونی ثابت 0.1 مولار و در ph ثابت در مخلوط حلال های اتانول – آب و استونیتریل – آب با استفاده از روش های اسپکتروفوتومتری مورد بحث و بررسی قرار گرفت. داده های اسپکتروفوتومتری با استفاده از نرم افزار squad پردازش شدند تا ثابت های تشکیل کمپلکس اندیکاتور – فلز را محاسبه کند. نتایج نشان می دهد که درصد حلال آلی در مخلوط حلال ...

Determination of serum estradiol levels by radiometric and chemiluminescent techniques.

The ability to precisely measure circulating levels of hormones is a foundation of modern endocrinology. For assisted reproductive technologies such as in vitro fertilization (IVF), accurate determination of circulating levels of estradiol are crucial for patient management, retrieval of fertilizable oocytes, and successful pregnancy outcome. For many years, circulating levels of estradiol were...

Determination of Solubility Parameters of Ibuprofen and Ibuprofen Lysinate.

In recent years there has been a growing interest in formulating solid dispersions, which purposes mainly include solubility enhancement, sustained drug release and taste masking. The most notable problem by these dispersions is drug-carrier (in)solubility. Here we focus on solubility parameters as a tool for predicting the solubility of a drug in certain carriers. Solubility parameters were de...
