Application Brief

Rapid LC Analysis of Cephalosporins Using Quasar Biphenyl Column

The aerobic mold which yielded cephalosporin C was found in the sea near a sewage outfall nearby Cagliari harbour, Sardinia, by the Italian pharmacologist Giuseppe Brotzu in July 1945. Since their discovery and subsequent commercialization in 1964, the cephalosporins today are broad-spectrum ß-lactam antibiotics used for the treatment of a number of bacterial conditions including septicaemia, pneumonia and meningitis. The pharmacology of cephalosporins is similar to that of the penicillin class of compounds. This application brief describes use of a Quasar biphenyl column in the analysis of several cephalosporins, a mixture of first and second generation ß-lactam antibiotics.

Rapid and Robust HPLC Analysis of Indoxyl Sulfate Using Quasar C18 Column

Indoxyl sulfate is one of the most extensively studied solutes that accumulates in the plasma when the kidneys fail. Originally called "indican", it was first isolated by Obermayer and Popper in 1911. High concentrations of indoxyl sulfate in blood plasma are known to be associated with the development and progression of a number of pathological conditions including chronic kidney disease and vascular disease. The scientific literature documents the use of older generation C18 columns, using type A silicas. This application brief will illustrate the application of a new generation C18 column, based on type B silica, for the analysis of indoxyl sulfate, Figure 1, as part of a research study to measure the total levels in a simulated blood serum environment.

Application Note

HPLC Analysis of Metformin Using a Quasar C18 Column with USP

Metformin belongs to a class of drugs known as biguanides and contains the active ingredient metformin hydrochloride. Metformin oral tablets are used, in combination with diet and exercise, to treat high blood glucose levels in patients with type 2 diabetes mellitus. Tablets are often used as monotherapy, or in combination with other anti-diabetic agents or insulin.

This application brief describes the use of a Quasar C18 column for the analysis of metformin hydrochloride RS in accordance with Dissolution Test 3 in the United States Pharmacopoeia (USP) monograph for metformin hydrochloride tablets.
